Prof Cryan profiled in Science

19 May 2020

'Meet the ‘psychobiome’: the gut bacteria that may alter how you think, feel, and act' in an article in 'Science' by Elizabeth Pennisi published 


'Gut bacteria are key to proper immune system development and maintenance, and studies show that having the wrong mix of microbes can derail that process and promote inflammation'. 'Animal studies by Cryan and others have bolstered the idea that gut microbes can influence the brain. Rats and mice given fecal transplants from people with Parkinson’s, schizophrenia, autism, or depression often develop the rodent equivalents of those problems. Conversely, giving those animals fecal transplants from healthy people sometimes relieves their symptoms. The presence or absence of certain microbes in young mice affects how the mice respond to stress as adults, and other mouse studies have pointed to a role for microbes in the development of the nervous system'.

This is the second entry for the Cryan lab in Science this year following their paper in November on “Microbiota and the Social Brain
