[HTML][HTML] Selenium levels affect the IL-4–induced expression of alternative activation markers in murine macrophages

SM Nelson, X Lei, KS Prabhu - The Journal of nutrition, 2011 - Elsevier
Selenium (Se), in the form of selenoproteins, imparts many health benefits with
antiinflammatory properties. Previous studies have shown that Se supplementation of
macrophages negatively regulates the LPS-dependent production of inducible NO synthase
(iNOS), a proinflammatory gene. Therefore, we hypothesized that L-arginine, a substrate for
iNOS, is acted upon by arginase-I (Arg-I), contributing to the resolution of inflammation. We
investigated the antiinflammatory activity of Se using LPS and IL-4–treated C57BL/6 murine …
