title: Protective effect of adenylate deaminase (from Penicillium lanoso-viride) against acute infections in mice.
abstract: We examined the effects of the immunomodulator-adenylate deaminase (E.C. 3.5.4.6) from Penicillium lanoso-viride on experimental mice infections. Prophylactic intraperitoneal administration of adenylate deaminase (ADA) increased survival time and numbers of survivors after infection with Salmonella typhimurium, Pseudomonas aeruginosa and influenza A (H3N2) virus. Protection against influenza virus after intranasal ADA application was also observed. The influence of ADA was time and dose dependent. The most pronounced protection was obtained by administration of 3 U ADA/mice 24 h prior to infection. ADA had no antibiotic effect against these bacterial strains. Protective effects of ADA were studied in immunosuppressed mice under different regimes of treatment including cyclosporin A and trypan blue. The results indicated, that the protective effect of ADA is of a complex nature and probably depends on both T-cell and macrophage components.
