Calcitriol treatment of primary human bronchial epithelial cells infected with rhinovirus 16 (RV-16) increased the secretion of pro-inflammatory cytokines, including C-X-C motif chemokine ligand 8 (CXCL8) and CXCL10, crucial in the recruitment of macrophages, neutrophils, and T cells in the site of infection [53]. This evidence concerns the gene CXCL8 and infection.
