[Immunostimulating and protective effects of terrilytin preparations in staphylococcal infection].

Abstract

In mice infected with staphylococci there was observed less pronounced development of the immune response to sheep red blood cells (SRBC) than in intact animals subjected only to immunization. Administration of free terrilytin to the infected mice increased the immune response development induced by SRBC while the use of immobilized terrilytin normalized it. The supernatant liquid of the spleen cells (SLSC) from the mice treated with the free of immobilized terrilytins stimulated development of the immune response to SRBC in the infected animals and inhibited the function of the suppressor cells in the spleen. The immunomodulating and protective effects of the SLSC fractions isolated with column chromatography on Sephadex G-150 were investigated. Substances of the low molecular fraction of the SLSC proteins (molecular weight of 10-15 kD) from the mice treated with the terrilytins showed immunostimulating and protective properties. The factors inducing both the activity types included peptides and the ribonucleotide component playing a significant role in realization of the immunostimulating and protective effects of the free and immobilized proteases.
