Our research is focused on understanding and elucidating mechanisms of immune protection and regulation, which operate at the mucosal barrier of the intestine. We recently found that CD4 T cells harbor an unexpected degree of plasticity where mature CD4 T helper (Th) cells upon repeated antigenic stimulation under non-immunogenic conditions, are able to terminate the expression of the Th transcription factor, ThPOK, and gradually "reprogram" to MHC class II restricted CD4 cytotoxic T lymphocytes (CD4+CTL). At steady state, CD4+ CTL remain quiescent however under challenging conditions, these cells can become potent killer cells. Moreover, defects in the "reprogramming" process lead to the generation of pathogenic effector cells or excessive suppressive cells which respectively induce inflammatory diseases or impede on the protective capacity of the immune system to defeat not only pathogens but also tumor cells. Overall, based on the insights we are gaining from our research, a clear picture emerges which indicates that the mucosal immune defense adapts to the local environment and specializes to provide the most efficient and immediate protection in the face of preserving the integrity of the most critical mucosal barrier of the body. Using large data base approaches, we are currently dissecting the mechanisms and identify the network of factors which drive the reprogramming and control the function of CD4 CTL in mucosal-, antiviral-, and anti-tumor immunity as well as in autoimmunity. The discovery of LncRNAs as a novel layer of control over the functional fate of CD4 T cells has opened up a whole new field of research and new opportunities for medical intervention strategies.
In another study, we are aiming to understand the fate decisions and functional imprinting mediated during thymic development and self-antigen-based selection and the consequences this has on autoimmunity and immune anti-tumor surveillance (pathogenic and beneficial self-based immunity).
