Delayed Hypersensitivity in vitro. III. Effect of Cortisone on Cytotoxicity of Mumps Viral Antigen.

Abstract
Experimental mumps virus infections in guinea pigs are characterized in vivo by a positive delayed hypersensitive skin test reaction to viral antigen and in vitro by a cytotoxic effect of mumps virus antigen on cells from tissues cultivated from mumps-infected animals. Cortisone protects against this in vitro cytotoxicity of mumps virus.
