Effect of Neutrophils on Nitric Oxide Production from Stimulated Macrophages
Background: During the initial phase of an infection, there is an upregulation of inducible nitric oxide synthase in the macrophages for the production of nitric oxide. This is followed by the recruitment of polymorphonuclear leukocytes (neutrophils) which release arginase. Arginase competes with inducible nitric oxide synthase for a common substrate L-arginine. Objective: To investigate whethe...

متن کاملOrigins of tumor-associated macrophages and neutrophils.
Tumor-associated macrophages (TAMs) and tumor-associated neutrophils (TANs) can control cancer growth and exist in almost all solid neoplasms. The cells are known to descend from immature monocytic and granulocytic cells, respectively, which are produced in the bone marrow. However, the spleen is also a recently identified reservoir of monocytes, which can play a significant role in the inflamm...
متن کاملThe secretion of preformed granules by macrophages and neutrophils.
The ability of macrophages and neutrophils to defend tissue homeostasis and participate in inflammatory responses depends on their ability to mobilize granule-membrane proteins and granule content into their external milieu and into phagosomes by regulated secretory processes. Many laboratories have invested much time and effort into furthering our understanding of vesicular transport and secre...
متن کاملNeutrophils and Macrophages: the Main Partners of Phagocyte Cell Systems
Biological cellular systems are groups of cells sharing a set of characteristics, mainly key function and origin. Phagocytes are crucial in the host defense against microbial infection. The previously proposed phagocyte cell systems including the most recent and presently prevailing one, the mononuclear phagocyte system (MPS), grouped mononuclear cells but excluded neutrophils, creating an unac...
