Biographical Sketch 
Chander Raman (b. 1961), Assistant Professor of Medicine, received his B.Sc. degree in Zoology from Madras University, India (1980). He subsequently received his M.S. degree in Microbiology from Idaho State University (1984) and Ph.D. degree in Microbiology from Southern Illinois University (1989) with special emphasis in immunology and host responses to infectious diseases. During his postdoctoral training with Dr. Katherine Knight at Loyola University Chicago, Stritch School of Medicine (1984-1989), he developed an interest in immunogenetics and regulation of lymphocyte activation. He continued his studies first as an Assistant Scientist at Hospital For Special Surgery, Cornell University Medical College (1994-1996) and more recently as an Assistant Professor in the Department of Medicine in the Division of Clinical Immunology and Rheumatology. He also has a secondary appointment in the Department of Microbiology.



Research/Clinical Interest
Title
Lymphocyte activation, immunopathogenesis of autoimmune diseases
Description
The projects in the laboratory are: (1) Role of CD5 in B-cell and T-cell development, differentiation, immunity and pathogenesis - related to this project we focus on B-1a B-cells, T-independent antibody responses, T-dependent antibody responses, autoreactive B-cell generation and persistence and regulatory B-cells. In this research area, my laboratory for several years has been interested in determining the physiological and biochemical activities of CD5, a regulator of activation in B-1a B-cells and T-cells. (2) Immunopathogenesis of MS – related to this project we focus on mechanisms regulating the activation of T-cells and differentiation to pathogenic (Th1, Th17 and ThIFNγIL-17 –dual producers), regulatory (nTreg, iTreg) Th subsets and cells of the innate immune system (dendritic cells, macrophages and microglia). Within this context a new area for the laboratory is the study of type 1 and type 2 interferons in the pathogenesis of MS and the mouse model, experimental autoimmune encephalomyelitis (EAE). (3) Therapeutic targeting of MS. All of the projects involved the study of signaling pathways driving the differentiation of both pathogenic and regulatory effector populations following stimulation of TLR and/or cytokine receptors.
