1 Large amounts of nitric oxide (NO) are produced by the inducible isoform of NO synthase (iNOS) in many cell types once the iNOS gene is transcriptionally activated. Nitric Oxide nitric oxide synthase 2, inducible Mus musculus
2 Large amounts of nitric oxide (NO) are produced by the inducible isoform of NO synthase (iNOS) in many cell types once the iNOS gene is transcriptionally activated. Nitric Oxide nitric oxide synthase 2, inducible Mus musculus
3 In primary mouse peritoneal macrophages elicited by thioglycolate broth, expression of iNOS follows treatment with IFN-gamma and is synergistically increased by the addition of bacterial LPS. thioglycolate broth nitric oxide synthase 2, inducible Mus musculus
4 Mouse peritoneal macrophages cultured in the presence of IFN-gamma alone or IFN-gamma plus LPS rapidly depleted the medium of L-arginine, a substrate for iNOS, and stopped producing NO. Arginine nitric oxide synthase 2, inducible Mus musculus
5 L-Arginine repletion also boosted NO production by macrophages cultured for up to 2 to 3 days in the presence of IFN-gamma plus LPS, but thereafter, iNOS was inactive in these cells whether or not L-arginine was repleted. Arginine nitric oxide synthase 2, inducible Mus musculus
6 Activity of iNOS could be restored by adding both L-arginine and fresh IFN-gamma with or without LPS, likely reflecting the synthesis of new enzyme. Arginine nitric oxide synthase 2, inducible Mus musculus
