immune system
• an acidic extracellular environment has less inhibition on LPS-induced TNF secretion by macrophages than in controls
• at pH 6.4, TNF secretion is reduced by 40% compared to a 80% reduction in wild-type controls
• similar results occur when TNF secretion is induced by polyI:C agonist
|
• in microglia cells derived from homozygous mice, extracellular acidic pH inhibits lipopolysaccharide -induced IL-1beta production

skeleton
• the BMC/TV values are significantly reduced by ovariectomy
|
• the ovariectomized mutant mice display a greater reduction in the femoral BV/TV than the ovariectomized control mice
