Mammalian cells use cytosolic nucleic acid receptors to detect pathogens and
other stress signals. In innate immune cells the presence of cytosolic DNA is
sensed by the cGAS-STING signalling pathway, which initiates a gene expression
programme linked to cellular activation and cytokine production. Whether the
outcome of the STING response varies between distinct cell types remains largely
unknown. Here we show that T cells exhibit an intensified STING response, which
leads to the expression of a distinct set of genes and results in the induction
of apoptosis. Of note, this proapoptotic STING response is still functional in
cancerous T cells and delivery of small molecule STING agonists prevents in vivo
growth of T-cell-derived tumours independent of its adjuvant activity. Our
results demonstrate how the magnitude of STING signalling can shape distinct
effector responses, which may permit for cell type-adjusted behaviours towards
endogenous or exogenous insults.The cGAS/STING signalling pathway is responsible
for sensing intracellular DNA and activating downstream inflammatory genes. Here
the authors show mouse primary T cells and T leukaemia are hyperresponsive to
STING agonist, and this strong STING signalling is associated with apoptosis
induction.
