Biographical Sketch of NHLBI Director Claude Lenfant, M.D.

Dr. Lenfant was appointed NHLBI director on July 6, 1982. He received his B.S. degree in 1948 from the University of Rennes, France, and his M.D. in 1956 from the University of Paris.

Upon completing his medical studies, he assumed the position of director of the Laboratory of Experimental Surgery, Centre Marie Lannelongue, in Paris. While there he directed research into extracorporeal oxygenation of blood and use of deep hypothermia in cardiac surgery.

In 1957 Dr. Lenfant was appointed postdoctoral fellow at the University of Buffalo, and the following year continued that appointment at Columbia University in New York. His postdoctoral interests were directed to respiratory and circulatory physiology.

Returning to France, he assumed a teaching position as assistant professor of physiology at the University of Lille. He soon returned to the United States, however, where he was appointed to a joint position in the departments of medicine and of physiology and biophysics at the University of Washington, Seattle. He rose to the rank of professor in both departments. He published extensively on dynamics of blood-gas exchange in humans and various other species under normal conditions and under conditions of altitude and pressure. Respiratory adaptation to hypoxia, anemia, alkalosis and acidosis also were investigated.

In 1970 Dr. Lenfant was appointed the first associate director for lung programs of the then NHLI, and also assumed the position of acting associate director for collaborative research and development programs. This program evolved into the Division of Lung Diseases, formed in 1972, with Dr. Lenfant as its director. For his accomplishments he was awarded the HEW Superior Service Honor Award in 1974. The Division of Lung Diseases continued to grow and to coordinate a strong and diverse program of research into the prevention, diagnosis and treatment of lung diseases.

He became NIH associate director for international research and director of the Fogarty International Center in 1981, positions he held until his appointment as director of NHLBI. In 1983 he was elected member of the Institute of Medicine, NAS. He was named Distinguished Executive of the Senior Executive Service in 1991 and Federal Executive of the Year for 1992 by the Institute Alumni Association.

NHLBI Programs

The NHLBI's research programs are implemented through five extramural units: the Division of Heart and Vascular Diseases (DHVD), the Division of Epidemiology and Clinical Applications (DECA), the Division of Lung Diseases (DLD), the Division of Blood Diseases and Resources (DBDR), and the National Center on Sleep Disorders Research (NCSDR), and one intramural unit, the Division of Intramural Research (DIR). The NHLBI also has primary responsibility for the Women's Health Initiative. Research grants, program project grants, specialized center grants, cooperative agreements, research contracts, research career development awards, and institutional and individual national research service awards are used to support research and research training. Specific programs foster career development for minority students and scientists. Included are minority institutional research training awards, minority school faculty development award, research development award for minority faculty, and short-term training for minority students program. A more detailed description of NHLBI activities is in the NHLBI Factbook.

Extramural Research

Division of Heart and Vascular Diseases

The DHVD plans and directs a coordinated research program on the causes of heart and vascular diseases and on their prevention, diagnosis, and treatment. Multidisciplinary programs are supported to advance basic knowledge of disease and to generate the most effective methods of clinical management and prevention. Clinical trials are an important part of the research program; they provide an opportunity to test and apply promising preventive or therapeutic measures.

The Division has three major programs:

  • The Heart Research Program
  • The Vascular Biology Research Program
  • The Clinical and Molecular Medicine Program
It also has a Research Training and Special Programs Group.

The Heart Research Program supports clinical and fundamental studies in cardiac diseases, from embryonic life through adulthood. Specific areas include heart arrhythmias and electrical abnormalities, cardiomyopathies, cardiac development, pediatric heart disease, heart failure and cardiogenic shock, ischemic heart disease, inflammation and infectious disorders of the heart, exercise physiology, heart transplantation, and myocardial preservation. Other areas focus on normal and abnormal cardiac development, diabetic cardiomyopathy, gene-nutrient interactions in the pathogenesis of congenital heart defects, pathogenesis of heart failure, electrical remodeling, and various aspects of HIV infection as it relates to the heart. Specialized Centers of Research support studies on heart disease in blacks; ischemic heart disease, sudden cardiac death, and heart failure; and pediatric heart disease.

The Vascular Biology Research Program supports investigations in atherosclerosis, hypertension, vascular biology, and gene therapy for prevention and treatment of vascular diseases. Other areas are the etiology, pathogenesis, and treatment of cardiovascular disease (CVD) in diabetes mellitus and cardiovascular complications of HIV/AIDS. Specific programs include Specialized Centers of Research on molecular medicine and atherosclerosis, molecular genetics of hypertension, and basic and clinical gene therapy.

The Clinical and Molecular Medicine Program supports clinical, basic, and engineering research on CVD and health. Its scope includes genetic, genomic, and proteomic research; bioengineering; informatics and simulation; and clinical trials in disease mechanisms, management, and treatment. Although the primary focus is on studies involving patients with CVD, rather than the general population, other areas, such as the role of lipid interventions, nutrition, and exercise also are pursued. Bioengineering projects include innovative ventricular assist systems, implantable total artificial hearts, genetically enhanced cardiovascular implants, magnetic resonance angiography, mathematical models and simulation, imaging, biomaterials, tissue engineering, and other therapeutic devices. Genomic applications include the development of research tools such as genetically altered animals, support of human and model organism genomic resources, and development of bioinformatics to understand heart, lung, and blood diseases.

The Research Training and Special Programs Group is responsible for planning, conducting, analyzing, and directing a program for developing highly specialized human resources related to research and career development in cardiovascular diseases. Research training and career development programs are available for all stages in the professional development of the investigator, from pre- and postdoctoral levels to the senior investigator level.

Division of Epidemiology and Clinical Applications

The DECA plans, directs, and evaluates research on the causes, prevention, diagnosis, and treatment of cardiovascular, lung, and blood disease. It supports epidemiologic studies, clinical trials, demonstration and education research, disease prevention and health promotion research, and basic and applied research in behavioral medicine. In addition, it provides training and career development in cardiovascular, lung, and blood diseases and sleep disorder research for individuals at all stages of their professional training.

The Division is organized into two programs, the Clinical Applications and Prevention Program and the Epidemiology and Biometry Program, and the Office of Biostatistics Research.

The Clinical Applications and Prevention Program oversees research in prevention of heart and vascular, pulmonary, and blood diseases through activities such as clinical trials, health promotion and disease prevention, community interventions, health education research, nutrition research, and behavioral medicine. It supports large-scale, multicenter studies in hypertension, heart failure, hyperlipidemia, and platelet aggregation. The prevention and education programs support research to test effectiveness and demonstrate capability of preventive interventions that are designed to reduce cardiovascular risk factors. Ongoing programs include studies of prevention and treatment of hyperlipidemia, obesity, and other risk factors in children and adolescents; interventions to improve delivery of care using evidence-based guidelines; and community-wide prevention programs. The behavioral medicine programs encourage basic and clinical collaborations between biomedical and behavior scientists.

The Epidemiology and Biometry Program supports and conducts epidemiological studies of heart and vascular, lung, and blood diseases using field studies and clinical epidemiology, genetic epidemiology, and analytical resources. It focuses on development and progression of CVD risk factors in children and young adults; development and progression of atherosclerosis measured non-invasively in middle-aged or older adults; and development and progression of overt cardiovascular and pulmonary disease in older adults. Also emphasized are genetic and environmental influences on CVD and its risk factors; trends in incidence, prevalence, and mortality from CVD, stroke, peripheral vascular disease, congestive heart failure and cardiomyopathy; and relationships between insulin, insulin resistance, and overt diabetes and CVD and its risk factors. Other programs investigate incidence of and mortality from cardiovascular, lung, and blood diseases. Research strategies apply family, longitudinal, demographic information and vital statistics to study natural history, etiology, and epidemiology of those diseases.

The Office of Biostatistics Research (OBR) provides statistical expertise to members of all Divisions of NHLBI and performs diverse functions in planning, design, implementation, and analysis of NHLBI-sponsored studies. It develops new statistical solutions to problems for which techniques are not yet available. Designing efficient trials and monitoring data collection are important functions of the Office. Research includes new methods for permitting extension or early suspension of ongoing randomized clinical trials, methods for analyzing complex survival data, trials with multiple endpoints, and trials involving multiple treatments.

Division of Lung Diseases

The DLD plans and directs a coordinated research program on the causes and progression of lung diseases and on their prevention, diagnosis, and treatment. Its activities focus on understanding the structure and function of the respiratory system, increasing fundamental knowledge of mechanisms associated with specific pulmonary disorders, and applying new findings to evolving treatment strategies for patients.

The Division is divided into two programs:

  • The Airway Biology and Disease Program
  • The Lung Biology and Disease Program

The Airway Biology and Disease Program focuses on basic and clinical research, education, and training related to chronic obstructive pulmonary diseases, asthma, cystic fibrosis, control of breathing, bronchiolitis (bronchopneumonia), respiratory neurobiology, sleep, and other adult airway diseases. Research programs include delineation of the genetic and metabolic defects underlying pulmonary complications associated with cystic fibrosis and alpha-1-proteinase inhibitor deficiency, pathogenesis of smoking- and environmentally related airway diseases, genetics and treatment of asthma, gene therapy, and neurochemicals in control of breathing.

In 2001 the first international guidelines for the diagnosis, management, and prevention of chronic obstructive lung disease were issued by an international team of scientists from the Global Initiative for Chronic Obstructive Lung Disease (GOLD) created by the NHLBI and the World Health Organization. The GOLD Workshop Report, which provides evidence-based recommendations for clinical management of COPD, is the first step in an international effort to boost awareness of COPD and improve the way it is treated.

The Lung Biology and Disease Program supports research, education, and training programs in lung cell and vascular biology; lung growth and development and pediatric lung disease; acute lung injury and critical care medicine; interstitial lung diseases, including pulmonary fibrosis; and AIDS and tuberculosis. Representative projects include a clinical network for treatment of acute respiratory distress syndrome, an epidemiologic study of sarcoidosis; activities to address pathobiology of tuberculosis (TB) and Pneumocystis carinii and basic cell biology of pulmonary manifestations of AIDS; and a program to develop lung specific drug delivery systems for enhanced TB treatment.

Division of Blood Diseases and Resources

The DBDR plans and directs a coordinated research program on the causes and prevention of blood diseases and disorders. Areas of interest encompass a broad spectrun of research from stem cell biology to medical management of blood diseases, with a focus on non-malignant and pre-malignant processes. The Division also has a major responsibility to improve the adequacy and safety of the Nation's blood supply. It has recently taken a leading role in developing cell-based therapies, combining the expertise of transfusion medicine and stem cell technology with the exploration of repair and regeneration of human tissues and biological systems.

The Division is organized into two major programs:

  • The Blood Diseases Program
  • The Blood Resources Program

The Blood Diseases Program supports research and training in nonmalignant disorders of red blood cells and disorders of hemostasis and thrombosis. A major goal is to find additional platelet inhibitors, anticoagulants, and fibrinolytic agents that will improve specificity and reduce side effect when used in treatment of thrombotic and thromboembolic disorders. It also includes a comprehensive program focusing on reducing morbidity and mortality caused by disorders of the hematopoietic system and preventing their occurrence. Diseases include sickle cell disease (SCD), thalassemia, Fanconi anemia, and Diamond Blackfan anemia.

The NHLBI supports 10 Comprehensive Sickle Cell Centers, which collectively form a SCD clinical research network, and which individually conduct basic and clinical research, as well as provide state-of-the-art patient care, educational activities for patients and health professionals, community outreach, and genetic counseling services.

Finding an effective treatment for hemophilia is another priority. Bleeding disorders associated with defects in coagulation proteins or abnormal platelet function, such as the immune thrombocytopenias, are also being studied. Other emerging areas being supported are gene transfer, clinical proteomics, inflammation and thrombosis, coagulation activation, autoimmune disease, and thrombotic complications of obesity, diabetes and cancer.

The Blood Resources Program plans and directs research and training in transfusion medicine, stem cell biology and disease, and clinical cellular medicine. Areas of interest in include transmission of disease through transfusion, development of methods to detect and inactivate viruses in donated blood, improvement of blood donor screening procedures, and identification of emerging diseases that may be transmitted by blood transfusions. It supports basic and clinical investigations related to transfusion immunobiology, focusing on graft versus host disease, graft versus leukemia effect, and dendritic cell therapies. The Program also developed two clinical research networks to promote efficient comparison of innovative treatment strategies-one for patients undergoing blood or marrow transplantation and the other for patients with hemostatic disorders such as idiopathic thrombocytopenia and thrombotic thrombocytopenic purpura. Specialized Centers of Research support collaborative studies on hematopoietic stem cell biology and transfusion biology and medicine.

National Center on Sleep Disorders Research

The NCSDR plans, directs, and supports a program of basic, clinical, and applied research; health education; and prevention-related research in sleep and sleep disorders. It maintains surveillance over developments in its program areas; assesses the national need for research on causes, diagnosis, treatment, and prevention of sleep disorders and sleepiness; and coordinates sleep research activities across the Federal Government and with professional, voluntary, and private organizations. Research topics include cellular, molecular, and genetic basis of sleep and its disorders; epidemiology of sleep and sleepiness in health and disease; effects of sleep loss on the waking function of the brain, other systems, and behavior; and pathophysiology and optimal management of common sleep disorders. Development of programs to train investigators to become sleep researchers is also a priority.

The NCSDR works closely with the NHLBI Office of Prevention, Education, and Control (OPEC) on sleep disorder education for physicians and the community. Reaching the young with information about sleep and sleep disorders is a major priority. In 2001 the Center implemented a five-year education initiative targeting young children - and their parents, teachers, and health care providers - with the message that adequate nighttime sleep - at least nine hours each night - is important to their health, performance, and safety. Garfield the Cat was chosen as the campaign's "Star Sleeper" and is being used to promote the importance of adopting healthy sleep habits.

In 2003, the NCSDR released the revised National Sleep Disorders Research Plan. The Plan summarizes advances in knowledge since the first plan was released in 1996, identifies gaps in our knowledge base, and recommends research priorities.

Women's Health Initiative

The WHI is a 15-year project consisting of three major components: a randomized controlled clinical trial of promising but unproven approaches to prevention, an observation study to identify predictors of disease, and a study of community approaches to developing healthful behaviors. The clinical trial and the observational study, consisting of more than 167,000 women, 50 to 79 years of age, will seek to answer questions on benefits and risks of hormone replacement therapy and changes in dietary patterns and calcium/vitamin D supplements in disease prevention. The program was originally established by NIH in 1991 to address the most common causes of death, disability, and impaired quality of life. On October 1, 1997, management of the WHI was transferred to the NHLBI.

NHLBI FY 2003 Research Initiatives

In FY 2003, the NHLBI initiated programs to:

  • Promote research on molecular and cellular mechanisms involved in hypersecretion of mucus and mucous cell metaplasia in chronic airway diseases such as COPD, asthma, and cystic fibrosis.
  • Identify mechanisms of fetal hemoglobin (gamma-globin) gene silencing during normal human development.
  • Stimulate research on the biologic basis of various obesity-related CVD, including atherosclerosis, hypertension, cardiomyopathies, heart failure, and arrhythmias/sudden death.
  • Facilitate clinical application of mesenchymal stem cells to hematopoietic and non-hematopoietic stem cell transplantation by stimulating basic research on mesenchymal stem cell biology.
  • Encourage basic research on stem cell biology and the use of stem cells in cellular therapies for cardiovascular, lung, and blood diseases and sleep disorders.
  • Identify and validate molecular targets that interfere with fibrogenesis and to characterize agonist or antagonists that interact with these or previously identified targets to attenuate, halt, or reverse development of pulmonary fibrosis.
  • Support development and evaluation of innovative science training programs to provide minority students in grades K-12 with the exposure, skills, and knowledge that will encourage them to pursue studies in biomedical and behavioral sciences.
  • Elucidate basic mechanisms of drug effects and adverse reactions in order to optimize drug treatment in individual patients and mitigate serious adverse response or lack of response to therapy.
  • Establish a clinical research network to conduct multiple, short-term, multicenter, therapeutic intervention trials in patients with moderate to severe COPD.
  • Improve therapeutic and preventive approaches for atherosclerotic arterial diseases of the peripheral vasculature.
  • Provide insight into the pathogenesis of peripheral vascular, pulmonary, and lymphatic diseases, and lead to new and more effective treatment by encouraging research on the cellular and molecular mechanisms that contribute to the functional heterogeneity of adult peripheral, pulmonary, and lymphatic vessels
  • Elucidate the role of blood cellular components in the genesis and progression of AIDS by stimulating collaboration among scientists studying SIV/SHIV disease in primates and investigators with expertise in tuberculosis, other pulmonary diseases, and cardiovascular disorders.

Office of Prevention, Education, and Control

The OPEC, located in the NHLBI Office of the Director, relays results of heart, lung, and blood research to health care professionals, their patients, and the public. It disseminates and translates up-to-date research findings that will help practitioners be more effective and provides scientific knowledge to patients and the public that will enable them to make "healthy decisions."

The institute has six areas of educational emphasis; high blood pressure, cholesterol, asthma, heart attack alert, sleep disorders, and obesity. Three - high blood pressure, cholesterol, and obesity - address major modifiable risk factors for CVD.

The National High Blood Pressure Education Program (NHBPEP) was established in 1972 to reduce death and disability associated with high blood pressure through professional, patient, and public education. Its mission is to translate and disseminate research findings and scientific consensus to improve medical care outcomes and the public's health. In collaboration with a coordinating committee consisting of national medical, public health, and voluntary organizations and other Federal agencies, the NHBPEP strives to increase public awareness about high blood pressure, promote activities to encourage detection of the disease especially among underserved groups, and encourage hypertensive patients to seek medical care and follow their doctor's advice.

In 2003, the NHBPEP released the Seventh Report of the Joint National Committee on the Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC VII) . The new guidelines streamline the steps by which doctors diagnose and treat patients, recommend the use of diuretics as part of the drug treatment plan for high blood pressure in most patients, and include a new "prehypertension" level at which people need to reduce their risk of high blood pressure by making lifestyle changes.

The National Cholesterol Education Program (NCEP) was initiated in 1985 to educate health professionals and the public about high blood cholesterol as a risk factor for coronary heart disease (CHD) and about benefits of lowering cholesterol levels to reduce illness and death from CHD. Program success can be seen by the fact that, from 1983 to 1995, the percentage of the public who had their cholesterol checked rose from 35 to 75 percent - showing that 70 to 80 million more Americans were aware of their cholesterol level in 1995 than in 1983. Additionally, in 1995, physicians reported initiating diet and drug treatment at much lower cholesterol levels than in 1983.

In 2002, the NCEP disseminated the new Clinical Guidelines on Cholesterol Management in Adults (ATP III), developed a Web-based kit of materials derived from the Guidelines, and distributed ATP III Opinion Leader kits to encourage influential members of the medical community to use the Guidelines and communicate their importance to professional colleagues. The NCEP is also developing a new patient booklet on therapeutic lifestyle changes based on recommendations in the Guidelines.

The National Asthma Education and Prevention Program (NAEPP) was initiated in 1989 to raise awareness of asthma as a serious, chronic disease and to promote more effective management of asthma through professional, patient, and public education. The NAEPP has created partnerships with local asthma coalitions to stimulate grassroots asthma control programs, particularly in underserved, high-risk communities that are disproportionately affected by asthma. These programs are directed to health care providers, patients, and their families and encourage them to follow the NAEPP Expert Panel Report 2: Guidelines for the Diagnosis and Management of Asthma.

In 2002, the NAEPP, in partnership with the Department of Education, revised the NIH publication, Managing Asthma: A Guide for Schools. The updated guide contains action steps for principals, school nurses, teachers, guidance counselors, and maintenance staff. Other publications include: Making A Difference in the Management of Asthma: A Guide for Respiratory Therapists, developed in partnership with the American Association of Respiratory Care; and Key Clinical Activities for Quality Asthma Care, developed in partnership with the Centers for Disease Control and Prevention (CDC) for employee health benefits managers and other health care planners.

The National Heart Attack Alert Program (NHAAP) was initiated in 1991 to reduce morbidity and mortality from acute myocardial infarction and sudden cardiac arrest through education of health care professionals, patients, and the public about the importance of rapid identification and treatment of individuals with heart attack symptoms. In 1997, the program broadened its scope to include early identification and treatment of individuals with acute coronary syndromes encompassing unstable angina as well as acute heart attack. The program develops educational materials on symptom recognition and appropriate reactions and collaborates with health care organizations and state and Federal agencies.

In 2001 the NHAAP, in partnership with the American Heart Association, the American Red Cross, and the National Council on Aging, launched a major campaign to urge physicians and health care providers to educate their patients about heart attack risk, warning signs, and steps to increase survival. As part of the campaign to increase awareness of the need to act fast when someone may be having a heart attack, the NHLBI established a Web page, "Act in Time to Heart Attack Signs" (, with educational material for heath professionals, patients, and the public.

The NHLBI Obesity Education Initiative (OEI) was initiated in 1991 to inform health care professionals and the public on the health risks associated with overweight and obesity. Obesity is not only an independent risk factor for CVD, but also a contributor to high blood pressure and high blood cholesterol and is related to sleep apnea. The goal of the OEI is to encourage individuals to adopt heart-healthy eating patterns and physical activity habits to reduce the prevalence of overweight and obesity and their related CHD risk factors along with sleep apnea, and thereby reduce morbidity and mortality from CHD.

In FY 2002, the NHLBI Hearts N' Parks project in 50 high-risk communities continued to gain momentum. The goal is to reduce obesity and risk of coronary heart disease by creating model community-based programs to increase the number of children, adults, and seniors practicing heart-healthy behaviors in order to reduce obesity, improve nutritional status, and increase physical activity. In addition, the NHLBI served on the Steering Committee for the Surgeon General's Call to Action to Prevent and Decrease Overweight and Obesity.

The NHLBI Ad Hoc Committee on Minority Populations was established in 1975 to facilitate communication between minority communities and the NHBPEP. As the institute developed new programs, the role of the committee was expanded. Today, it provides direct input to the NHLBI regarding development and implementation of all outreach and education projects specifically designed to improve the health status of minority populations.

The NHLBI initiated several cardiovascular health outreach and education activities to address the overall Healthy People (HP) 2010 goals of eliminating health disparities and increasing the quality and years of healthy life for all Americans. Included among the activities are the Baltimore City Cardiovascular Health Partnership to promote cardiovascular health in African American communities, the Salud para su Corazón (Health for Your Heart) project to promote heart health in Latino communities, and the Strengthen the Heartbeat of American Indian and Alaska Native Communities to increase knowledge and promote heart health among three tribal communities (the Ponca Tribe of Oklahoma, the Bristol Bay Area Corporation in Western Alaska, and the Laguna Pueblo in New Mexico). The NHLBI has also initiated a program of Enhanced Dissemination and Utilization Centers (EDUCs) dedicated to the elimination of cardiovascular health disparities in underserved populations. The EDUCs form the foundation of what is intended to become a nationwide network of performance partners that will use the Institute's science-based information to develop educational strategies to improve the health behaviors and health status of individuals in high-risk communities. The EDUCs are a key part of NHLBI's response to the Healthy People (HP) 2010 Objectives for the Nation.

The NHLBI Women's Heart Health Education Initiative was established in 2001 to expand, intensify, and coordinate cardiovascular disease education for women. In 2002, the NHLBI launched The Heart Truth – a campaign directed at women 40 to 60 years old and at health professionals – to increase awareness about heart disease in women, improve detection and treatment of risk factors by health professionals, and motivate national and community organizations to become involve in heart health education. Special attention is given to minority women who are at increased risk for developing heart disease. In 2003, the campaign unveiled the Red Dress Project. This groundbreaking project, supported by Mercedes-Benz USA and 7th on Sixth (the producers of Mercedes-Benz Fashion Week), launched a red dress icon to raise awareness of women's risk of heart disease, give a sense of hope that women can reduce their risk and empower them to do so, and provide a clear call to action coupled with a sense of urgency.

Intramural Research

The Division of Intramural Research (DIR) plans and directs laboratory and clinical research in heart, blood vessel, lung, and blood diseases. In addition, it supports the development of technology related to cardiovascular and pulmonary diseases.

The Division has two major programs: the Clinical Research Program and the Laboratory Research Program.

The Clinical Research Program plans and directs clinical research in heart, vascular, pulmonary, and blood diseases. It encourages implementation of new technology and application of new techniques and treatments through clinical trials. The Program oversees four branches and one laboratory.

The Cardiovascular Branch develops new diagnostic and therapeutic modalities for treatment of cardiovascular diseases. It focuses on mechanistic studies and novel clinical protocols.

The Hematology Branch investigates normal and abnormal hematopoiesis in patients and in cellular, molecular, and immunologic laboratory research. It focuses on bone marrow failure, viral infections of hematopoietic cells, gene therapy of hematologic and malignant diseases, bone marrow transplantation, and mechanisms of immunologically mediated syndromes like graft-versus-host disease and autoimmune diseases.

The Molecular Disease Branch conducts research into the genetic disorders of lipoprotein and cholesterol metabolism with special emphasis on the diagnosis, genetic analysis, and treatment of patients with genetic dyslipoproteinemias and atherosclerosis.

The Pulmonary Critical Care Medicine Branch conducts research related to the lung and the cardiovascular system to define, at a molecular level, normal function and disease. It focuses on integration of biochemical, molecular biological, and immunological events in order to understand intra- and intercellular communication and organ function.

The Laboratory of Animal Medicine and Surgery provides laboratory animal care, facilities, and services for all phases of animal experimentation as required by the intramural research programs, including surgery, clinical medical care, animal resources, and diagnostic services.

The Laboratory Research Program plans, coordinates, and manages research in cellular and molecular biology, cell signaling, genetic studies, biophysics and biochemistry, and other applied sciences. The Program oversees 11 laboratories.
