  • The basic premise for immune algorithm is distinguishing self from nonself. This is achieved by different modules of host immune system. The ‘innate’ immune system recognizes the nonself based on predominantly nonself-associated molecular patterns (PAMPs), while the ‘adaptive’ immune axis adapts to the nonself molecular determinants. These two work together toward an effective immune response. An effective immune response to an invading pathogen (nonself) leads to protective immunity and a defective response leads to overt infection. On the other hand, an unintended response to the self-entities leads to autoimmune disorders, while a misjudged tolerance to the altered self contributes to tumorigenesis. Our research broadly concentrates on role of innate immune axis in the crossroads of infection, autoimmunity and cancer. Dendritic cells (DCs) are the innate cells with most of the decision-making responsibilities for an ensuing immune response or tolerance. We try to decipher the governing principles of self-nonself discrimination by the germline-encoded invariant pattern recognition receptors (PRRs) expressed by DCs and how they work in a given clinical context. Broadly the research directions of our lab are:

    • Innate immune regulation and molecular mechanisms of dendritic cell function
    • Role of innate immune deregulation in autoreactive inflammation
    • Deciphering the role and modulation of dendritic cells in tumor microenvironment
    • History and philosophy of self-nonself recognition

    Ours is a relatively new laboratory in IICB (located in the IICB-Translational Research Unit of Excellence, Salt Lake Campus) that promises a lot of fun and exciting science, which will be achieved through hard work of all its members. Feel free to contact Dipyaman if you feel like sharing the excitement.

    At this point of time our laboratory cannot accommodate any more fellows. But from time to time we look for individuals with excellent academic credentials and predoctoral [NET (CSIR/UGC] or postdoctoral fellowships — candidates with some background in human physiology, or immunology with exposure to molecular biology techniques are preferred. Medical graduates/postgraduates (MBBS/MD) interested in biomedical research should also feel free to discuss possibilities of joining the team. Interested candidates may contact directly at dipyaman.iicb@gmail.com along with curriculum vita and a brief statement on research interests.
