Abstract
The in vivo effect of morphine, methadone and cocaine on murine peritoneal macrophage-mediated cytostasis and macrophage supernatant mediated cytostasis was investigated. In addition, the activity of drugs of abuse was studied on IL-1 alpha and TNF production by activated murine macrophages. A highly depressive effect on macrophage-mediated cytostatic activity and a decrease of IL-1 alpha and TNF levels were found in the supernatants of activated macrophages observed in morphine- and cocaine-treated mice. Conversely, a significant impairment of macrophage functions was not observed in methadone-treated mice. Our results suggest that the inhibition of macrophage defensive functions caused by drugs of abuse may be an important cofactor in the pathogenesis of infectious diseases.Entities:
