[HTML][HTML] NADPH oxidase is internalized by clathrin-coated pits and localizes to a Rab27A/B GTPase-regulated secretory compartment in activated macrophages

Here, we report that activation of different types of tissue macrophages, including microglia,
by lipopolysaccharide (LPS) or GM-CSF stimulation correlates with the quantitative
redistribution of NADPH oxidase (cyt b 558) from the plasma membrane to an intracellular
stimulus-responsive storage compartment. Cryo-immunogold labeling of gp91 phox and
CeCl 3 cytochemistry showed the presence of gp91 phox and oxidant production in
numerous small (< 100 nm) vesicles. Cell homogenization and sucrose gradient …
