Scientists are investigating how bacteria in the gut might affect our mood, as part of a new study being carried out at Nottingham Trent University.

Bacteria, or "microbiome", in the is believed to play an important role in regulating brain function and behaviour. This "gut community" can become unhealthy, however, due to a range of factors such as or stress, making individuals susceptible to ill-health and .

Some scientists believe that depression may be the result of inflammation, and could be improved by enhancing gut microbiome health.

The new study will examine the relationship between , brain function, depression and immune system in the general population.

It is being led by Nottingham Trent University's Dr Alex Sumich, in collaboration with the University of Reading's Professor Glenn Gibson and King's College London's Professor Anthony Cleare.

Dr Nadja Heym, a psychologist in Nottingham Trent University's School of Social Sciences, said: "With up to a quarter of people experiencing depression in their lifetime, this illness has wide-reaching effects on the nation's quality of life and economy.

"Current therapies may improve symptoms, but some patients will be unresponsive to them or suffer side effects.

"Having a better understanding of the relationship between the gut and the brain is vitally important in order to potentially reduce risk and improve quality of life in people suffering from this debilitating illness."

People are being invited take part in this research, which will involve completing an online questionnaire about psychological wellbeing. Some participants will also be invited to have further assessments to test for , inflammation and microbiota.
