Antibiotic treatment alleviates Alzheimer’s disease symptoms in male mice

Neuroscience News
Study reports specific gut bacteria can influence the development of Alzheimer's disease. In mouse models, long term antibiotic treatment reduced inflammation and the formation of amyloid plaques. However, the reduction was only seen in males. Additionally, the antibiotic treatment altered the activation of microglia in the male mouse models.... Read More...
