How does Vitamin A promote immune function? A. A derivative of vitamin A, retinal, helps to regulate the expression of genes that promote the differentiation of precursor epithelial cells into mucus-secreting cells that have a barrier function. B. A derivative of vitamin A, retinoic acid, helps to regulate the expression of genes that promote the differentiation of precursor white blood cells into phagocytes and lymphocytes. C. Two of these choices accurately describe how Vitamin A promotes immune function. D. A retinoic acid-protein receptor complex binds to mRNA promoting the translation of proteins involved in the differentiation of precursor white blood cells into phagocytes and lymphocytes.
