Abstract
Background Studies have shown that lung inflammation affects lung function, with life-threatening results. Vitamin D may play an important role in inhibiting inflammatory cytokines. Vitamin D deficiency is related to several lung problems, including respiratory distress syndrome, alveolar inflammation, epithelial damage, and hypoxia. Few studies have evaluated the benefits of vitamin D in preventing inflammation in alveolar cells. Material/Methods We developed a cell inflammation model induced by lipopolysaccharide (LPS) treatment. The effects of vitamin D on LPS-induced inflammation in A549 cells were examined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, and the anti-inflammatory mechanism of vitamin D was evaluated using western blot analysis. Results Our results indicated that vitamin D promoted A549 cell survival following LPS-induced inflammation by downregulating nuclear factor nuclear factor kappa light chain enhancer of activated B cells, tumor necrosis factor-α, interleukin (IL)-1β, IL-6, and IL-12. Conclusions Our results indicated that vitamin D has the potential to manage lung inflammation, although further studies are needed.
