ONLINE COVER Diet and the Developing Immune System. Shown are a rhesus macaque mother and her infant. Whether breast-fed or bottle-fed, the diet of a newborn infant macaque dictates the composition of its gut microbiota, which then helps to direct early development of the infant's immune system (Ardeshir et al.). The differences in gut microbiota and immune cell subsets between breast-fed and bottle-fed infant macaques is sustained even after weaning, when they are fed the same diet.
