Influence of phospholipids from Listeria monocytogenes and Aspergillus fumigatus on the bactericidal and fungicidal activity of mouse peritoneal macrophages.
Investigations were carried out on an influence of phospholipids from A. fumigatus and L. monocytogenes on the bactericidal and fungicidal activity of mouse peritoneal macrophages. L. monocytogenes bacilli and C. neoformans fungi served as the experimental microorganisms. Phospholipids from A. fumigatus and L. monocytogenes were shown to significantly increase macrophage activity under in vivo and in vitro conditions. This was accompanied by an intensified bactericidal and fungicidal activity of extracts from the lysosomal fraction of phagocyte examined. Phospholipid-stimulated macrophages were observed to liberate bactericidal factors into the culture fluid. Lymphocytes had no influence upon this process.
