“…Crucially, calcitriol has long been shown to possess immune-regulatory properties and may inhibit key steps in this inflammatory process. [31][32][33] In present study 25-hyroxyvitamin D level is significantly lower in patient group compared with control group (18.2±10.9 vs 28.8±21ng/mL). Vitamin D deficiency was present in 81.4% patient in case group whereas 57.7% in control group.…”

“…Di Rosa M et al found that 1,25-dihydroxyvitamin-D(3) influences macrophages chemotaxis and differently modulates the expression of Interleukin-1 beta (IL-1β), Interleukin-6 (IL-6), tumor necrosis factor alpha (TNF-α) and TLRs in the two different stages of monocytes/macrophage maturation [56]. Campbell GR et al report that TLR8 activation in human macrophages induces the expression of the human cathelicidin microbial peptide (CAMP), the VDR and cytochrome P450, family 27, subfamily B, polypeptide 1 (CYP27b1), which 1α-hydroxylates the inactive form of vitamin D, 25-hydroxycholecalciferol, into its biologically active metabolite.…”

“…The mechanism behind the down-regulation of pro-inflammatory cytokine expression by 1,25D3 is suggested to involve a VDR-associated reduction of pattern recognition receptor TLR2, TLR4, dectin-1 and mannose receptor expression [27]. Lipopolysaccharide-stimulated production of IL-1β, IL-6 and TNFα is suppressed by 1,25D3 in human and murine monocytes/macrophages [28][29][30]. Interestingly, the down-regulation of pro-inflammatory cytokines upon stimulation with 1,25D3 seems to vary with the stage of monocyte/macrophage maturation, and, moreover, this effect seems to be dependent on MAPK phosphatase-1 [29,30].…”

Importantly, 1,25D3 enhances glucocorticoid-induced inhibition of lipolysaccharide-stimulated IL-6 in human monocytes, suggesting that 1,25D3 and glucocorticoids may act in synergy [31].…”
