Mechanisms of the immunostimulative activity. In the present paper, an investigation was carried out to clarify the mechanisms regarding immunostimulative activity of alpha-MPG and DPA. Phagocytosis of peritoneal macrophage was enhanced by high concentration of alpha-MPG, but was unaffected with DPA in vitro. Mice were immunized with an i.v. injection of sheep erythrocytes and 3 days later spleen cells were isolated and incubated with alpha-MPG and DPA FOR 24 HR. Although neither drug affected the number of recovered and living cells, hemolytic plaque forming cells were increased with alpha-MPG and there was a tendency to increase with DPA. Phytohemagglutinin-P and/or lipopolysacchride E. coli-induced blast formation was not reinforced by either drug in spleen cells of mice, and no mitogenic activity was found in the spleen cells. In the early stage of immuno-response to polyvinylpyrrolidone as a T cell independent antigen, the titre of antibody showed no increase after either drug. alpha MPG and DPA apparently act as potentiators in antigen modifications of macrophages.

UI	MeSH Term	Description	Entries
D008213	Lymphocyte Activation	Morphologic alteration of small B LYMPHOCYTES or T LYMPHOCYTES in culture into large blast-like cells able to synthesize DNA and RNA and to divide mitotically. It is induced by INTERLEUKINS; MITOGENS such as PHYTOHEMAGGLUTININS, and by specific ANTIGENS. It may also occur in vivo as in GRAFT REJECTION.

D008264	Macrophages	The relatively long-lived phagocytic cell of mammalian tissues that are derived from blood MONOCYTES. Main types are PERITONEAL MACROPHAGES; ALVEOLAR MACROPHAGES; HISTIOCYTES; KUPFFER CELLS of the liver; and OSTEOCLASTS. They may further differentiate within chronic inflammatory lesions to EPITHELIOID CELLS or may fuse to form FOREIGN BODY GIANT CELLS or LANGHANS GIANT CELLS.

D010587	Phagocytosis	The engulfing and degradation of microorganisms; other cells that are dead, dying, or pathogenic; and foreign particles by phagocytic cells (PHAGOCYTES).	Phagocytoses
D010835	Phytohemagglutinins	Mucoproteins isolated from the kidney bean (Phaseolus vulgaris); some of them are mitogenic to lymphocytes, others agglutinate all or certain types of erythrocytes or lymphocytes. They are used mainly in the study of immune mechanisms and in cell culture.
