CGAS and viral infectious disease: To explore the function of cGAS in response to viral infections, we infected the cGAS-KO DEF cells (cGAS-/-) and the normal control DEFs (cells transfected with empty vector pX459-v2, EV) with DAdV B2, SBDSV and NDRV viral strains at the MOI of 0.25 and harvested at the indicated time points.
