COVID-19 infection can be inhibited by elements of the human microbiome

12/01/2021

In the human microbiome, researchers have identified metabolites (intermediate or end products of metabolism) that inhibit COVID-19 infection in cell-based models of the virus. The finding, reported this week in the journal mSphere, an open-access journal of the American Society for Microbiology, is yet another example of the wealth of information that can be gained by studying the human microbiome, the collection of microbes, bacteria, fungi and viruses that live on and inside the human body. The finding may also help in the development of new therapeutics that can battle COVID-19 infections.

Targeting the brain's immune cells may help prevent or treat Alzheimer's disease

12/01/2021

A gene mutation linked to Alzheimer's disease alters a signaling pathway in certain immune cells of individuals with the disease, according to a new study by scientists at Weill Cornell Medicine. The team also found that blocking the pathway—with a drug that's currently being tested in cancer clinical trials—protects against many features of the condition in a preclinical model. The results could lead to new strategies to block the development of Alzheimer's disease or slow its progression.
