Several lines of evidence suggest that targeting the body’s defense pathways might help treat a subset of people with the psychiatric disorder. But many open questions remain.
The COVID-19 pandemic is still with us. Biomedical innovation has rallied to address that pressing concern while continuing to tackle broader research challenges.
The scientific community bid farewell to researchers who furthered the fields of molecular biology, virology, sleep science, and immunology, among others.
Researchers develop a CRISPR-based, two-phage system that sensitizes resistant bacteria to antibiotics and selectively kills any remaining drug-resistant bugs.
The immune system tolerates the colonization of commensal bacteria on the skin with the aid of regulatory T cells during the first few weeks of life, a mouse study shows.
