[Effect of adjuvants on the cellular function of the monocytic phagocytosing system]. 1975

M E Bubashvili, and E L Khasman, and I Ia Uchitel'

The authors studied the effect of adjuvants differing by origin and physico-chemical nature (complete Freund's adjuvant, S. typhi endoxin, cadmium sulfate, iron trichloride) on the ingestion and digestion of erythrocytes of the sheep by the cells of monocytic phagocytizing system, on the persistence of the antigen in these cells, its complexation with the RNA-macrophages and the function of their lysosomal apparatus. The adjuvants change the phagocytizing capacity of the macrophages only in their administration in vivo. Administration to the animals of Freund adjuvant and of the S. typhic endotoxin somewhat increased the ingestion of the antigens, whereas the administration of FeCl3 and CdSO4 failed to change it or even somewhat decreased it. The capacity of ingestion of the antigen in vitro in macrophages obtained from the animals treated with the adjuvants was changed in comparison with the normal. All the adjuvants tested produced a marked action on the lysosomal apparatus of the cells of the monocytic phagocytizing system: they changed the activity of catepsin, promoted the accumulation and the retention in the lysosomes of the highly immunogenic fractions of the antigen, and increased the permeability (except the CdSO4 of the lysosomal membranes in the cells of the antigen binding with the RNA of the cells of the peritoneal exudate or the splenic cells.

UI	MeSH Term	Description	Entries
D008247	Lysosomes	A class of morphologically heterogeneous cytoplasmic particles in animal and plant tissues characterized by their content of hydrolytic enzymes and the structure-linked latency of these enzymes. The intracellular functions of lysosomes depend on their lytic potential. The single unit membrane of the lysosome acts as a barrier between the enzymes enclosed in the lysosome and the external substrate. The activity of the enzymes contained in lysosomes is limited or nil unless the vesicle in which they are enclosed is ruptured or undergoes MEMBRANE FUSION. (From Rieger et al., Glossary of Genetics: Classical and Molecular, 5th ed).	Autolysosome,Autolysosomes,Lysosome
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.

D009000	Monocytes	Large, phagocytic mononuclear leukocytes produced in the vertebrate BONE MARROW and released into the BLOOD; contain a large, oval or somewhat indented nucleus surrounded by voluminous cytoplasm and numerous organelles.	Monocyte
D010587	Phagocytosis	The engulfing and degradation of microorganisms; other cells that are dead, dying, or pathogenic; and foreign particles by phagocytic cells (PHAGOCYTES).	Phagocytoses
D002403	Cathepsins	A group of lysosomal proteinases or endopeptidases found in aqueous extracts of a variety of animal tissues. They function optimally within an acidic pH range. The cathepsins occur as a variety of enzyme subtypes including SERINE PROTEASES; ASPARTIC PROTEINASES; and CYSTEINE PROTEASES.	Cathepsin

D004731	Endotoxins	Toxins closely associated with the living cytoplasm or cell wall of certain microorganisms, which do not readily diffuse into the culture medium, but are released upon lysis of the cells.	Endotoxin
