Hybrid immunity generates improved cell response to fight SARS-CoV-2 infections

People who were infected with SARS-CoV-2 before being vaccinated generate an immune response more specific to fighting viral infections, and produce a broader antibody response, than do people whose only protection is the vaccine, according to researchers at the University of Washington School of Medicine.

Omicron variant found to be less effective at blocking cellular defense mechanism against viruses

A new study by researchers from the University of Kent and the Goethe University Frankfurt shows that the SARS-CoV-2 Omicron variant is less effective than Delta at blocking a cellular defense mechanism against viruses, the so-called “interferon response”.

Targeting the inflamed intestinal wall may be a novel way to prevent inflammation in HIV patients

New UCLA-led research in mice suggests that adding a certain type of tomato concentrate to the diet can reduce the intestinal inflammation that is associated with HIV. Left untreated, intestinal inflammation can accelerate arterial disease, which in turn can lead to heart attack and stroke.
