Abstract
Vitamin D has a range of non-skeletal health effects and has been implicated in the response torespiratory infections. The aim of this study was to assess the effect of vitamin D on the response ofepithelial cells, neutrophils and macrophages to lipopolysaccharide (LPS) stimulation. BEAS-2B cells(airway epithelial cell line) and primary neutrophils and macrophages isolated from blood samples werecultured and exposed to LPS with and without vitamin D (1,25(OH)2D). The production of IL-6, IL-8,IL-1β and TNF-α of all cells and the phagocytic capacity of neutrophils and macrophages to E. coli wereassessed. Vitamin D had no effect on BEAS-2B cells but enhanced the production of IL-8 in neutrophils(p=0.007) and IL-1β in macrophages (p=0.007) in response to LPS. Both vitamin D (p=0.019) andLPS (p<0.001) reduced the phagocytic capacity of macrophages. These data suggest that the impactof vitamin D on responses to infection are complex and that the net effect will depend on the cellsthat respond, the key response that is necessary for resolution of infection (cytokine production orphagocytosis) and whether there is pre-existing inflammation.
