STEP 444: The Role of Intestinal Microbiota (CE: 1.5)

Description:

Historically, intestinal bacteria were thought to be beneficial simply by outcompeting pathogenic bacteria. Research has shown that gut bacteria interact with host systems far more than originally thought, influencing multiple systems, including the nervous system and the brain. Through production of neurotransmitter molecules, such as serotonin, gut bacteria have far-reaching effects. Recent research has investigated links to host health and effects of gut bacteria on obesity, metabolism, and immune function, as well as effects on the brain including stress responses, anxiety disorders, mood, depression, and autism. This article seeks to describe the gut microbiome, its relationship with the brain, effects on serotonin production, and ongoing research in this dynamic area.

Learning Objectives:

• Discuss the synthesis of serotonin
• Discuss the gut microbiome
• Reflect on the link between gut microbiota and chronic conditions
