Human T cells

T cells are critical for host defense, but they can be a double-edged sword, inappropriately recognizing beneficial symbiont microbes, environmental substances, foods, or self. Starting with humans, we use cutting-edge techniques including single-cell transcriptomics and mass spectrometry to discover and target novel factors driving both ‘good’ and ‘bad’ immunity in human effector T cells.
