T cells are important in mounting immune responses to a host of pathogens, and they have also been implicated in autoimmune disease. By examining the variability in gene expression in stimulated T cells over time from a multiethnic cohort of healthy humans, Ye et al. identified specific genetic polymorphisms that explain differences among individuals in response to pathogens. Furthermore, a candidate gene approach led to the identification of a single-nucleotide polymorphism that controls the response of the autoimmune-associated IL2RA gene. This study helps us understand the degree to which immune responses are driven by the environment or by an individual’s physiological or genetic factors.
