Designer peptides show potential for blocking viruses, encourage future study

Chemically engineered peptides could prove valuable in the battle against some of the most persistent human health challenges. New findings demonstrate how researchers can engineer peptides capable of selectively and specifically binding to polysialic acid (PSA) — a carbohydrate that is present in many human cells and plays a key role in various physiological and pathological processes, including neurological development and disease progression.
