Dialing up the activity of a protein called SYK in the brain’s “janitors” could provide an avenue to treat Alzheimer’s and other neurodegenerative diseases.

Scientists studying pathogens such as Chlamydia, Legionella, and Listeria get a master class in how to control the internal workings of mammalian cells.

Various microbes, including several human pathogens, hijack the cell’s skeleton, membranes, and protein-making machinery to make themselves at home.

Bats are known for staying healthy even while harboring viral infections. Now, research sheds light on how their unusual immune system evolved.

Pregnancy-induced changes in the immune system are key to a successful birth. Understanding those changes could allow researchers to protect both mother and child.

Aberrant immune activation, the main cause of prematurity and stillbirths, could be preventable through interventions such as maternal vaccination. 

The ability to activate different sets of genes has likely helped the chytrid fungus Batrachochytrium dendrobatidis spread widely in amphibians, resulting in global population declines. 

A high-fat diet induced changes to the animals’ vaginal microbiomes that boosted survival after exposure to the virus.

Mammals that give birth to live young may have evolved to make use of the remnants of viruses in their genomes to ward off pathogens, a study suggests. 

Recent studies have lent support for a variety of hypotheses explaining the debilitating symptoms affecting millions of people after SARS-CoV-2 infection.  

Immune cells deliver packages of telomeres to T cells, helping them retain their virus-fighting function over time, research suggests.

Several mechanisms contribute to the increased transmissibility of this SARS-CoV-2 variant.

IgA antibodies appear to bind to specific species of commensal gut bacteria in mice, according to a study.
