Abstract

The following studies were performed to investigate the mechanism(s) by which the complement system limits Sindbis virus infection in the central nervous system of mice. After the intracerebral inoculation of Sindbis virus, no differences in mortality or viral growth in the central nervous system were observed between normal mice and mice depleted of complement by treatment with cobra venom factor. In addition, animals that had been inoculated subcutaneously with Sindbis virus and depleted of complement after the viremic phase had ended did not show any differences in mortality or viral growth in the central nervous system. In contrast, it was found that after the intracardiac inoculation of virus, complement-depleted mice demonstrated a defect in the clearance of infectious virus from the blood. These studies suggest that the increased growth of virus in the brains of complement-depleted mice after the subcutaneous inoculation of Sindbis virus is due to a defect in clearance of infectious virus from the bloodstream rather than to a primary defect within the central nervous system.
