Scientists discover a completely different way to fight viruses
Researchers have discovered a unique antiviral protein in sea anemones that functions differently than human antiviral proteins, despite structural similarities. This finding suggests that animal immune systems evolved through multiple, diverse strategies rather than a single ancestral path.
Why it matters
This discovery challenges long-standing evolutionary theories and provides new insights into the fundamental mechanisms of immunity.
Scientists have uncovered a previously unknown way that sea anemones defend themselves against viruses, revealing that the evolution of animal immune systems may be far more diverse than previously believed. The newly identified defense relies on a protein that closely resembles one of the most important antiviral proteins in humans, yet performs the opposite function while still being essential for protecting the animal from infection. The findings suggest that evolution produced more than one successful strategy for fighting viruses across the animal kingdom.
