    Cowpox virus expresses the serpin CrmA (cytokine response modifier A) in order to avoid inflammatory and apoptotic responses of infected host cells. The targets of CrmA are members of the caspase family of proteases that either initiate the extrinsic pathway of apoptosis (caspases 8 and 10) or trigger activation of the pro-inflammatory cytokines interleukin-1beta and interleukin-18 (caspase 1).
