Sea Anemones Reveal Antiviral Defense That Reverses the Human Immune Playbook
Researchers at the Hebrew University of Jerusalem discovered a protein called CARDIB in sea anemones that suppresses — rather than activates — antiviral defenses, yet is essential for fighting infection. Published in Nature Ecology & Evolution, the study used CRISPR to show that removing the gene made anemones far more vulnerable to viruses. The work suggests different animal lineages evolved fundamentally distinct molecular antiviral strategies.
