Infections originating from subcutaneous tissues are among the most common invasive infections caused by group A streptococcus (GAS) and associated with systemic coagulation activation. The role of intrinsic coagulation factors on GAS virulence has recently been determined, but the role of the extrinsic coagulation factor VII is unknown. Using a mouse model, in which GAS-sepsis emerges from a subcutaneous infection, we show that FVII is a negative acute phase protein. F7 knockdown using antisense oligonucleotides resulted in an attenuated systemic coagulation activation and inflammatory response in septic animals. The findings indicate FVII's ability to modify the host response.
