Dr. Rajalingam Raja serves as the Laboratory Director, Clinical Consultant and Technical Supervisor for the UCSF Immunogenetics and Transplantation Laboratory. Dr. Raja received his Ph.D. from the Department of Transplant Immunology and Immunogenetics, All India Institute of Medical Sciences, New Delhi. Six-years of pre-doctoral studies in HLA diversity, followed by six-years of post-doctoral research in NK cell immunogenetics at Stanford, plus eighteen-years of experience in clinical histocompatibility laboratory directorship in the high volume transplant centers at UCLA and UCSF have shaped Dr. Raja into one of the uniquely experienced investigators committed to the fields of histocompatibility, immunogenetics and transplant immunology.

  • Natural killer (NK) have been implicated in control and clearance of malignant and virally infected cells, regulation of adaptive immune responses, rejection of bone marrow transplants, autoimmunity and the maintenance of pregnancy. Human NK cells largely use a family of Human Leukocyte Antigen (HLA)-specific Killer cell Immunoglobulin-like Receptors (KIR) to recognize and respond to the unhealthy target cells. KIR and HLA loci are both polygenic and substantially polymorphic, and they map to distinct human chromosomes (Chromosomes 19 and 6, respectively).

    KIR and HLA gene families segregate independently, yielding many individuals who express KIR receptors for which they lack HLA class I ligands, and vice versa, thus creating human diversity in the number and type of KIR-HLA inherited gene pairs, which potentially could influence the health and disease status of a given individual. The overall goal of our research is to understand the diversity of KIR receptors, HLA ligands, and KIR-HLA gene combinations in populations and their relevance in human health and disease.
