Bioengineered bacteria sneak past solid tumor defenses to guide CAR T cells’ attacks.

Regulatory T cells in the colon travel to muscles to promote wound healing in mice, raising questions about how antibiotics may impact injury recovery.

Biofilms are home to millions of microbes, but disrupting their interactions could produce more effective antibiotics.

Bacteria in the gut influence the production of antibodies and themselves secrete metabolites. In a pregnant woman, these compounds may influence immune development of her fetus.

George Church is at it again, this time using multiplex gene editing to create virus-proof cells, improve organ transplant success, and protect elephants.

In the evolutionary arms race between pathogens and hosts, genetic elements known as transposons are regularly recruited as assault weapons for cellular defense.

Metabolic disrupters, phages, and other approaches are going to be needed to treat the broadest possible range of patients infected by bacterial pathogens resistant to multiple drugs.

In record time, scientists have gone from harvesting antibodies against SARS-CoV-2 from survivors of coronavirus infections to testing the antibodies’ safety as a drug in humans.

Through their effects on metabolism and immunity, bacteria in the gut affect whether medications will be effective for a given patient.

Researchers develop a CRISPR-based, two-phage system that sensitizes resistant bacteria to antibiotics and selectively kills any remaining drug-resistant bugs.
