Research Description


Naïve T cells are thought to be quiescent cells with no active functional characteristics. After activation, the majority of microRNAs are reduced in naïve T cells. We observed that some naïve T cells highly expressed certain effector cytokines and probably certain microRNAs. These cytokine expressing naïve T cells were found in peripheral blood and tumor tissues, and enriched in umbilical cord blood. After TCR engagement, these naïve T cells lose their cytokine expression. Our research goals are to understand the phenotype and sources of these naïve T cells,  determine whether these naïve T cells play an active role in functionally shaping the immune response, and explore the mechanisms by which they maintain their effector property in the context of naïve nature.
