[Immunomodulating properties of the antigens of the cell walls of nontoxigenic Corynebacterium diphtheriae].

The total protein fraction was obtained by extraction with nonionic detergent NP-40. The fraction composition and molecular parameters were studied with DDS-Na electrophoresis in polyacryl amide gel. Common properties of the Corynebacterium diphtheriae protein fraction 66 kD and an analogous fraction of the cell walls of staphylococci and the measles virus were shown with immunoblotting. Cell-mediated mechanisms of the immune response to contact with antigens of Corynebacterium diphtheriae cell walls were revealed.
