The effects of lysozyme dimer (2 and 20 μg/kg) administered i.p. once and four times to mice on the phagocytic and killing ability of peritoneal macrophages, interleukin-1 (IL-1) production by murine macrophages stimulated in vitro with lipopolisaccharide of E. coli and expression of thymocyte, splenocyte and mesenteric lymphonode cell CD3+, CD4+ and CD8+ markers were studied. It was found that lysozyme dimer administered once or four times at doses of 2 (μg/kg and 20 μg/kg augments the phagocytic and killing activity of peritoneal macrophages. The strongest stimulating effect was noted after four injections of lysozyme dimer at a dose of 20 μg/kg. Moreover, lysozyme dimer is able to modulate the production of IL-1 by murine macrophages stimulated in vitro with LPS. Exposure to four doses of lysozyme dimer (20 μg/kg) enhances the synthesis and release of IL-1, but this drug administered once (2 μg/kg and 20 μg/kg) or four times (2 μg/kg) decreases IL-1 production by peritoneal macrophages. It was also found that administration of lysozyme dimer at a dose of 20 μg/kg, irrespective of the number of doses applied, increases the percentage of CD4+ thymocytes and splenocytes. Moreover, exposure to four doses of lysozyme dimer (2 and 20 μg/kg) increases the percentage of CD4+ and CD8+ mesenteric lymphonode cells.
