CASP1 and infection: Notably, in high‐dose infection (YM = 1), STING‐ and Caspase1‐mediated signalling contributed equally to induce Socs1 expression, but diverse type I IFN production, which may arise from earlier onset time of Socs1 mRNA triggered by STING‐mediated pathway than Casp1‐dependent signalling.
