Common nutrient supplement choline may hold the answers to combating Alzheimer’s

Taking dietary choline supplements may help to protect the brain from Alzheimer's disease. Choline reduces the activation of microglia which, when overactivated, contribute to neuroinflammation and apoptosis associated with Alzheimer's. Choline also helps block the production of amyloid plaques.

Alzheimer’s disease risk gene APOE4 impairs function of brain immune cells

APOE4 increases the inflammatory response of human microglia while reducing cellular migration. The gene also impairs the metabolic activity of the immune cells. The findings show APOE4 has a profound impact on the basic functions of microglia.

Acute cerebellar inflammation and hyperexcitability induces ‘depression-like’ behavior

Acute inflammation of the anterior cerebellum resulted in depression-like symptoms in rodent models. Suppressing microglia helped reduce hyperexcitability and symptoms of depression.

Creation of new brain cells plays an underappreciated role in Alzheimer’s disease

Microglia may play a significant role in disrupting neurogenesis in those with Alzheimer's disease. When mice were given drugs which caused microglial cells to die, neurogenesis returned to normal.

Link between brain immune cells and Alzheimer’s disease development identified

The brain's immune cells may contribute to the development of Alzheimer's disease. Turning off microglia in specific areas of the brain prevented the formation of amyloid plaques. The findings could help pave the way for new treatments for Alzheimer's.

Gut microbes protect against neurologic damage from viral infections

A healthy and diverse microbiome is essential for quickly clearing viral infections in the nervous system to prevent risks associated with multiple sclerosis. Mice with lower gut bacteria had weaker immune responses and were unable to eliminate viruses, leading to worsening paralysis. Those treated with antibiotics before infection had fewer microglia.

Reducing brain inflammation could treat tinnitus and other hearing loss-related disorders

Rodent study reveals noise-induced hearing loss is associated with elevated expression of proinflammatory cytokines and microglia activation in the primary auditory cortex. Pharmacologically depleting microglia helps prevent tinnitus in mice with noise-induced hearing loss.
