Two independent groups suggest the suite of recent unexplained hepatitis cases may stem from coinfection with an adeno-associated virus and a helper adeno- or herpesvirus, a duo which may be especially virulent in children with a particular genetic variant.

Observational evidence for the connection is solidifying, and some clues are emerging about the mechanisms that may explain it.

A new platform for screening astrocyte reactivity helps researchers uncover potential therapeutic interventions to treat neurodegenerative conditions.

Haydeh Payami helped uncover the genetic basis of Parkinson’s disease. Now, she hopes to find new ways to treat the disease by studying the gut microbiome.

Historical samples of bloodstream infections hold secrets to Escherichia coli’s evolutionary history and the emergence of virulent clones.

Evidence thus far shows that pregnant people infected with SARS-CoV-2 are at higher risk for severe disease and death, as well as complications in their pregnancies.

The Biogen-developed treatment, called lecanemab, appears to have a more clear-cut effect on slowing the disease than the company’s previous Alzheimer’s drug, Aduhelm.

His work was pivotal to understanding the mechanisms of neurodegenerative diseases, particularly Alzheimer’s and Parkinson’s.
