How Pregnancy Turns the Stress Response on Its Head

Immune cells in the uterus and placenta of stressed pregnant mice were not activated, but researchers found increased levels of inflammation in the developing fetal brain. Additionally, prenatal stress led to reductions in gut microbial strains and functions, especially in those linked to inflammation.

Hunger Hormone Impacts Memory

The hunger hormone ghrelin doesn't just influence where and when animals eat, it also appears to have an impact on memory. Disrupting signaling of ghrelin to the vagus nerve caused rats to forget they had just eaten, even though the animals remembered they had just had access to food. Findings suggest disrupted ghrelin signaling could negatively impact episodic memory.

Bacteria in the Gut Have a Direct Line to the Brain

Sensory neurons that send signals from the intestines to the brain stem extend to the interface of areas of the intestine that are exposed to high levels of microbial compounds. Turning off the neurons, researchers observed activated neurons in the brainstem as well as activation of gut neurons that control intestinal motility. The findings shed light on the potential mechanisms behind neurological abnormalities and intestinal diseases, including IBS.

New gut-brain link: How gut mucus could help treat brain disorders

Changes in gut mucus may contribute to Alzheimer's, Parkinson's, and other neurological disorders. Researchers noted changes in types of gut mucus bacteria in those with a range of neurological disorders compared to their healthy peers. Findings suggest those with reduced gut mucus protection may be more susceptible to gastrointestinal problems.
