Vitamin D supplementation (1 μg/kg vitamin D daily by intragastric gavage for 10 days) also attenuates neuroinflammation through the up-regulation of the anti-inflammatory cytokines (IL-10, IL-4, and TGF-β) mRNA in a Parkinson’s disease animal model (55). The gene discussed is TGFB1; the disease is Parkinson disease.
