  • arginine pathway.3. The rate of nitrite production (in the absence of extracellular arginine) was reduced by culturing macrophages or monocytes in the presence of the glutaminase inhibitor 6-diazo 5-oxo norleucine.4. The rate and extent of arginase secretion, glutamine utilization, nitrite production (basal and lipopolysaccharide-stimulated) and phosphate-dependent glutaminase activity from BCG-activated macrophages was increased compared with resident cells.5. We suggest that the elevated arginase secretion rates in activated macrophages would effectively increase the intracellular concentration of arginine available for conversion to NO via inducible nitric oxide synthase, the expression of which is known to increase on activation of macrophages or monocytes. Additionally, the rate of L-arginine biosynthesis from glutamine may be increased on immunostimulation of the macrophage.'})"> QQ
