Complement proteins and macrophages. III. The production of factor B by particle-ingesting macrophages. 1981

A Miyama, and Y Kawamoto, and H Ichikawa, and T Moriyama, and K Okamoto, and T Takahashi

A kinetic study of factor B secretion by particle-ingesting macrophages showed that the ingestion of zymosan but not latex lead to an early suppression of factor B secretion followed by a significant enhancement. This dual response was proportional to the number of ingested zymosans. After a suppressive period of 24-48 hr, the ingested zymosan stimulated the synthesis of factor B. The response of acid phosphatase synthesis to ingested zymosan was the same as that of factor B, while the synthesis of lactic dehydrogenase proceeded without an early suppression. These results suggest that factor B should be considered an enzyme released into the lysosomes of macrophages.

UI MeSH Term Description Entries
D007770 L-Lactate Dehydrogenase A tetrameric enzyme that, along with the coenzyme NAD+, catalyzes the interconversion of LACTATE and PYRUVATE. In vertebrates, genes for three different subunits (LDH-A, LDH-B and LDH-C) exist. Lactate Dehydrogenase,Dehydrogenase, L-Lactate,Dehydrogenase, Lactate,L Lactate Dehydrogenase
D007840 Latex A milky, product excreted from the latex canals of a variety of plant species that contain cauotchouc. Latex is composed of 25-35% caoutchouc, 60-75% water, 2% protein, 2% resin, 1.5% sugar & 1% ash. RUBBER is made by the removal of water from latex.(From Concise Encyclopedia Biochemistry and Molecular Biology, 3rd ed). Hevein proteins are responsible for LATEX HYPERSENSITIVITY. Latexes are used as inert vehicles to carry antibodies or antigens in LATEX FIXATION TESTS. Latices,Latice
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.
