Professor of Immunobiology; Member of HTI and VBT
Al Bothwell graduated with an A.B. from Washington University in 1971, got a PhD from Yale in Sidney Altman’s lab in 1975 and then did a postdoc with David Baltimore at MIT where he established the genetic basis of the anti-NP idiotypic antibody response. He has been on the Immunobiology faculty at the Yale Medical School since 1982. He continued studies of B cell antibody diversity and memory and then worked on T cell receptor structure/function and signaling. He also developed the molecular genetics of the Ly6 gene family (aka Sca-1/Ly6A and Ly6C). Increasingly his work has shifted to studies of human immunity with development of humanized mouse models of vascular disease/transplantation, type 1 diabetes and cancer. Studies on gut inflammation in a genetic tumor model and Inflammatory Bowel Disease have lead most recently to contributions concerning wnt signaling to infections and asthma. His studies focus on the remarkable immunoregulatory properties of Wnt signaling that is both canonical and non-canonical and involves direct interaction with platelets.This is a basic mechanism for regulating tissue permeability affecting the mobility of lymphocytes and tumor cells.

Lieping Chen studies immune cell communications via cell surface protein-protein interactions. He is also interested in translating laboratory findings to treat human diseases including cancer, autoimmune diseases and infection.
In 1992, Dr. Chen showed the first proof-of-concept study that the B7-CD28 family molecules could be the targets for cancer immunotherapy. This study inspires subsequent studies targeting the B7-CD28 family molecules for the treatment of human cancer.
In 1999, Dr. Chen, then at the Mayo Clinic, first to discover a molecule he called B7-H1, which is now also known as PD-L1. He subsequently showed that PD-L1 is expressed by several types of tumors and that its activity can cause the death of T cells, thus preventing them from eliminating cancer cells. Bringing these lines of inquiry full circle, he later showed that blocking this interaction between PD-1 and PD-L1 by monoclonal antibodies improved the immune system’s ability to eliminate tumors in a 2002 paper. Chen’s work provided an important foundation for the subsequent development of immunotherapies designed to block this activity, and thereby enable more effective immune responses against cancer. Dr. Chen also initiated and help organized the first-in-man clinical trial of anti-PD-1 monoclonal antibody for treating human cancer in 2006, when he moved to the Johns Hopkins Medical Institute, and developed PD-L1 staining as a biomarker to predict treatment outcome. His discoveries directly led to the development of anti-PD-1/PD-L1 antibody therapy against broad spectrum of human cancers. These discoveries have revolutionized cancer treatment.
Other important breakthroughs made by Dr. Chen's laboratory include the development of an agonist antibody against the 4-1BB co-stimulatory pathway, also known as CD137. Multiple 4-1BB-targeting antibodies have since been developed and are now being evaluated in clinical trials for a variety of cancer types. Dr. Chen’s laboratory also discovered various molecular pathways with T cell costimulatory and coinhibitory functions and/or their applications in human disease treatment. These pathways include B7-H2 (ICOSL), B7-H3, B7-H4, B7-H5/CD28H, PD-1H (VISTA), TNFRSF19, RELT, LIGHT/HVEM, B7-H2/CD28/CTLA-4 (human), SALM5/HVEM, FGL1/LAG-3, Siglec-15 etc. Many of these findings are now being developed clinically for the treatment of human diseases.

Assistant Professor of Laboratory Medicine and Immunobiology
Dr. Foxman's research interest is understanding the natural mechanisms that protect the airway from respiratory viruses. Recent evidence shows that respiratory viruses enter the airway much more frequently than they cause illness. Current projects focus on (1) identifying the antiviral defense mechanisms of the airway epithelium, (2) understanding how the environment influences antiviral defense and tips the balance between health and disease upon exposure to a virus, and (3) using biomarkers of the body's response to infection to diagnose the cause of respiratory symptoms.
Background. Dr. Foxman received her M.D. and Ph.D. training at Stanford University, and her residency training in Clinical Pathology, a medical specialty devoted to diagnostic testing, at Brigham and Women's Hospital in Boston, MA. Her postdoctoral studies in host-virus interactions were conducted with the mentorship of Akiko Iwasaki in the Department of Immunobiology at Yale. These studies demonstrated mechanisms whereby cool ambient temperature permits growth of the common cold virus by diminishing antiviral responses of airway epithelial cells. Dr. Foxman is currently an Assistant Professor in the Yale Department of Laboratory Medicine.

Ph.D., University of Pennsylvania (1992)
William S. and Lois Stiles Edgerly Professor of Neurology and Professor of Immunobiology; Chair, Department of Neurology; Neurologist-in-Chief, Yale New Haven Hospital
Dr. Hafler is the William S. and Lois Stiles Edgerly Professor and Chairman Department of Neurology, Yale School of Medicine and is the Neurologist-in-Chief of the Yale-New Haven Hospital. He graduated magna cum laude in 1974 from Emory University with combined B.S. and M.Sc. degrees in biochemistry, and the University of Miami School of Medicine in 1978. He then completed his internship in internal medicine at Johns Hopkins followed by a neurology residency at Cornell Medical Center-New York Hospital in New York.
Dr. Hafler received training in immunology at the Rockefeller University then at Harvard where he joined the faculty in 1984. He was one of the Executive Directors of the Program in Immunology at Harvard Medical School and was on the faculty of the Harvard-MIT Health Science and Technology program where he was actively involved in the training of graduate students and post-doctoral fellows.
Hafler, in many respects, is credited with identifying the central mechanisms underlying the likely cause of MS. His early seminal work demonstrated that the disease began in the blood, not the brain, which eventually led to the development of Tysabri to treat the disease by blocking the movement of immune cells from the blood to the brain. He was the first to identify myelin-reactive T cells in the disease, published in Nature, showing that indeed, MS was an autoimmune disorder. He then went on to show why autoreactive T cells were dysregulated by the first identification of regulatory T cells in humans followed by demonstration of their dysfunctional state in MS. As a founding, Broad Institute member, Hafler identified the genes that cause MS, published in the New England Journal of Medicine and Nature. More recently, he identified the key transcription factors and signaling pathways associated with MS genes as potential treatment targets. Finally, he recently discovered that salt drives induction of these pathogenic myelin reactive T cells, both works published in Nature. Hafler was the Breakstone Professor of Neuroscience at Harvard, and became Chairman of Neurology at Yale in 2009, where he has built an outstanding clinical and research program that strongly integrates medical sciences. He has received numerous honors including the Dystel Prize from the AAN for his MS research and is among the most highly cited living neurologists.
C.N.H. Long Professor of Immunobiology and of Medicine (Endocrinology)
My background and research are in translational immunology. I am interested in understanding the basis for autoimmune diseases and developing new therapies based on our understanding of disease mechanisms. My focus has largely been in the field of autoimmune Type 1 diabetes. The work encompasses basic laboratory work understanding the regulation of autoreactive T cells to clinical trials that involve novel therapeutics. As part of these studies I have also been very interested in analysis of beta cell function in Type 1 diabetes.
Waldemar Von Zedtwitz Professor of Immunobiology and Molecular, Cellular and Developmental Biology; Professor of Molecular Cellular and Developmental Biology; Investigator, Howard Hughes Medical Institute
Akiko Iwasaki received her Ph.D. from the University of Toronto (Canada) in 1998, and her postdoctoral training from the National Institutes of Health (USA) (1998-2000). She joined Yale University (USA) as a faculty in 2000, and currently is an Investigator of the HHMI and Waldemar Von Zedtwitz Professor of Department of Immunobiology, and of Department of Molecular Cellular and Developmental Biology. Akiko Iwasaki’s research focuses on the mechanisms of immune defense against viruses at the mucosal surfaces. Her laboratory is interested in how innate recognition of viral infections lead to the generation of adaptive immunity, and how adaptive immunity mediates protection against subsequent viral challenge.
My laboratory uses intricate tumor models and advanced approaches to investigate immune cell interactions with developing tumors. My goal is to determine mechanistically why these interactions do not lead to more potent anti-tumor responses and to identify entry points for modulating these interactions through genetic manipulation and therapeutic intervention. My previous studies have focused on using established complex mouse models to investigate how subtypes of T cells in the tumor microenvironment impact tumor development. My laboratory will combine advanced genetic modeling of mice and immunologic techniques to address fundamental questions in tumor immunology.

Dr. Kavathas graduated with a B.A. in American Institutions, from the University of Wisconsin, writing her thesis on the role of Science in America in the 1960s. She obtained her Ph.D. in Genetics from the Department of Genetics, founded in 1921 as the first Genetics Department in the country. At Wisconsin with Dr. Robert DeMars on genetic analysis of the MHC region. As a postdoctoral fellowship at Stanford University with Dr. Leonard Herzenberg she developed a novel approach for cloning genes for cell surface proteins using the fluorescence activated cell sorter (FACS).
At Yale she continued her studies on CD8 and recently has focused on the functional relevance of four isoforms of the CD8b protein that exist in humans and great apes but not mice. They are differentially expressed in naive T cells, activated T cells, and memory T cells. Signal transduction by the isoforms is different given that they differ only in their cytoplasmic tail. The clinical relevance of these isoforms for adoptive immunotherapy with T cells is one focus of the lab.
