Moreover, Ren et al. [22] recently reported that the exon-1 UL37 (UL37x1) protein encoded by human cytomegalovirus (HCMV), in addition to inhibiting apoptosis, also inhibited the cGAS-STING pathway, which is important in viral infections because its activation leads to the expression of genes encoding proteins such as interferons, which consequently inhibit host innate immunity. This evidence concerns the gene CGAS and viral infectious disease.
