The Particulate Hydrolases of Macrophages
The influence of phagocytosis on the morphological and biochemical properties of macrophage hydrolase-containing granules has been studied in vitro. Following the uptake of large numbers of heat-killed bacteria, an intracellular rearrangement of hydrolytic enzymes occurred. This was associated with the solubilization of 50 to 60 per cent of the total cell content of acid phosphatase, cathepsin,...
متن کاملSecretion of lysosomal hydrolases by stimulated and nonstimulated macrophages
Peritoneal macrophages were obtained from untreated mice and from mice treated with thioglycollate medium (TA), proteose peptone medium (PP), or a suspension of streptococcus A cell wall material (SA). The biochemical and secretory properties of these cells in long term cultures (up to 2 wk) were compared. TA-elicited macrophages contained more protein, lactate dehydrogenase, lysosomal hydrolas...
متن کاملParticulate matter effects on peritoneal macrophages inflammatory function in C57BL/6 mice
Abstract Background: Urban air pollution represents a challenge in Tehran. Health care organs and physicians pay much attention because of health effect on mankind. Nowadays, a majority of air pollution related articles focus on particulate matter adverse effects on human health. Epidemiologic studies show the direct correlation between ambient particulate matter and risk of respiratory sys...
متن کاملRegulation of prostaglandin synthesis and of the selective release of lysosomal hydrolases by mouse peritoneal macrophages.
Macrophages isolated from the peritoneal cavity of untreated mice and maintained in tissue culture synthesize and release prostaglandins when challenged with zymosan. These cells also selectively release lysosomal acid hydrolases under the same conditions. The major prostaglandins released into the media are found to be prostaglandins E1, E2 and 6-oxoprostaglandin F1a, whereas prostaglandin F2a...
متن کاملBacterial lipopolysaccharide suppresses the production of catalytically active lysosomal acid hydrolases in human macrophages
Sub-microgram quantities of bacterial lipopolysaccharide (LPS) have been found to substantially reduce the intracellular catalytic activities of three representative lysosomal enzymes (namely, acid phosphatase, hexosaminidase, and beta-glucuronidase) in human monocyte-derived macrophages. This response was not associated with a concurrent increase in enzyme catalytic activity in the culture sup...
