The Aging Gut Microbiome Dysregulates the Immune System in Intestinal Tissue (opens in new tab)

With advancing age the composition of the gut microbiome changes in detrimental ways and the immune system becomes progressively incapable. These two aspects of aging do not happen in isolation from one another. The relationship between the aging of the gut microbiome and aging of the immune system is likely bidirectional. The immune system is responsible for gardening the gut microbiome, suppressing the populations of undesirable microbes, and so loss of immune function enables the growth in...
