Immune protein modification blocks viral replication, heart inflammation
Cleveland Clinic virology researchers have found that a specific protein modification to the immune protein MDA5 is key to how human bodies detect and respond to viruses and viral replication.
The PNASpublication explains how two protein…

Researchers put glycemic response modeling on a data diet
If you eat a snack — a meatball, say, or a marshmallow — how will it affect your blood sugar? It’s a surprisingly tricky question: the body’s glycemic response to different foods varies based on individual genetics, microbiomes, hormonal…
