Research Interest

Our laboratory is interested in understanding the immunological determinants underlying the establishment of protective humoral immunity. The major focus of investigations is to resolve the traits and function of a specialized subset of CD4 T cells known as follicular T helper (Tfh) cells in long-term protective immunity. The global aim is to identify and harness the positive attributes of Tfh cells for rational design of vaccines.

Summary of Research

Our lab works at the interface of basic and translational immunology. By providing help to B cells, Tfh cells are crucial to the development of germinal center derived high quality protective antibodies. The factors that govern the differentiation of potent Tfh cells and the biology of Tfh cells implicated in the development of optimal humoral responses remain largely uncharacterized. Therefore, the conceptual framework of our programs is to resolve the traits and function of Tfh cells in long-term sustained immunity. Moreover, we are also trying to understand the characteristics of immunological memory, with emphasis on the T cells, to Flavivirus and human Coronavirus. To this, we are integrating the viral immunology, deep immunophenotyping, immunogenomics, and metabolomics approaches to investigate the biology of CD4 T cells and Tfh cells in two different models; (i) Human vaccination. Here, we are studying the characteristics and clonotypic diversity of human Tfh cells established in response to licensed human vaccines like SA14-14-2 Japanese encephalitis (JE) vaccine, SARS-CoV-2 vaccines etc. To identify the ideal attributes of Tfh cells in long-term protective immunity, we are comparing the function and traits of Tfh cells induced in response to vaccine with the Tfh cells induced in case of successful recovery from natural infection. To do this, we have established the longitudinal cohorts for controlled vaccination and infection. Besides, we are also using mouse models to mechanistically investigate the biology of Tfh cells in protective immunity established by the human vaccines. (ii) Human infection. In this program, our attempts are focused on providing the insight into the immunological memory and cellular determinants of humoral responses to viruses like Dengue virus, JEV, SARS-CoV-2 etc. Here, we are exploring the biology of Tfh cells and related CD4 T-cell subsets in patients with diverse outcome of virus infection.
