[Interleukin-1 induction by different antigens and strains of Yersinia pestis bacteria in immunized mice]

In this work the influence of Y. pestis antigens (capsular antigen, mouse toxin, lipopolysaccharide, pesticin), as well as the products of gene expression localized on three Y. pestis resident plasmids, have been studied. Capsular antigen and some antigens coded for by plasmid pCad have been shown to possess essential activity in the initiation of the synthesis of interleukin-1. Mouse toxin and the products of plasmid pPst produce the opposite effect.
