Cum ajung coronavirusurile de la lilieci la oameni: un nou studiu indică rolul unei modificări genetice minore

A new study reveals that minor genetic changes in viruses can affect their interaction with the immune systems of different species, aiding their adaptation to new hosts. Researchers identified a mechanism that may facilitate the transmission of coronaviruses from bats to humans. By analyzing SARS-CoV-2 and a related bat coronavirus, they found that a single amino acid change in a viral protein alters immune responses. This research highlights how seemingly harmless viruses in animals can adapt to humans and cause severe diseases, suggesting potential early warning systems for identifying zoonotic threats.
