Link between intestinal inflammation and microbiome

Around 500 to 1,000 different types of bacteria, fungi and other microorganisms colonize our intestines. All of them together form the intestinal microbiome. As we now know, these microbes play an important role in maintaining ...

Age and aging have critical effects on the gut microbiome

Researchers at Cedars-Sinai have found that aging produces significant changes in the microbiome of the human small intestine distinct from those caused by medications or illness burden. The findings have been published in ...
