Growth Hormone Improves the Resistance of Thermally Injured Mice Infected with Herpes Simplex Virus Type 1

Abstract

Exogenous administration of rhGH caused an improvement in the resistance of burned mice to HSV-1 infection. In burned mice treated with rhGH, the impaired IFN-gamma responsiveness was restored and the generation of burn-associated suppressor macrophages was inhibited. IFN-gamma, a typical antiviral cytokine induced by rhGH through the regulation of the suppressor macrophage generation, may therefore play a role in the protection of burned mice infected with a lethal amount of HSV-1.
