title: [Specific structural features and immunomodulatory properties of the lipopolysaccharides of Pseudomonas bacteria].
abstract: The results of in vitro studies of the immunomodulatory action of the lipopolysaccharides (LPS) of the Pseudomonas bacteria--P. fluorescens biovar I strains IMV 4125 = ATCC 13525, IMV 7769, and IMV 1152; P. fluorescens biovar IV strain IMV 2111; P. syringae pv. syringae IMV 281 = CPPB 281 = ATCC 19310 and IMV 467; and P. wieringae IMV 7923--on the mouse spleenocytes and human peripheral blood mononuclear cells (PBMC), B lymphocytes, and T lymphocytes are described. The proliferative activity of mouse spleenocytes correlated with the degree of LPS toxicity. The PBMC mitogenic activity induced by the P. fluorescens IMV 7769 LPS preparation exceeded the activity of E. coli 026:B6 LPS. The immunomodulatory effect of LPS on T cells was strain and dose dependent. The LPS of P. syringae pv. syringae INV 467 displayed a comparatively pronounced immunomodulatory effect on human blood B lymphocytes.
