Scientists long believed that the COVID-19 pandemic originated from a Chinese wet market with bat coronaviruses as the likely source. However, bats themselves are surprisingly immune to these viruses due to their strong immune systems.
A recent study in Nature sheds light on how bats’ unique immune systems allow them to coexist with coronaviruses without showing symptoms. The researchers analyzed 10 new bat species and found that they exhibit more adaptations in their immune genes than other mammals, often at a faster pace.
This discovery also provides insights into bats’ evolutionary history, suggesting that their superpowered immune system evolved due to their ability to fly. The findings are promising for developing better medicines against viruses, with potential applications in preventing future pandemics.
