Prior infections appear to shield enteric neurons, preventing these key components of the body's "second brain" from dying off when future pathogens strike.
Human cells can be coaxed into preventing certain enveloped viruses (including HIV, Ebola, and parainfluenza) from escaping their membranes in the lab, a finding that could lead to novel treatments for many viral diseases.
Studying dozens of naturally occurring and laboratory-selected mutations in SARS-CoV-2, researchers found that the virus will need to pull off a genetic feat to become fully resistant to antibodies.
New research casts doubt on a genetic test used to screen would-be embryos for IVF implantation. The findings suggests that these embryos can develop into healthy babies regardless of whether or not they’ve been flagged as defective by the test.
Cohen, a physician-scientist exploring obesity and metabolic disease, has conducted groundbreaking research on the complex inner workings of fat tissue.
