Scientists from Heinrich Heine University Düsseldorf and Kiel University studied the immune system of the sea anemone Nematostella vectensis, an early-branching animal. They found that despite having only an innate immune system, the sea anemone can distinguish between beneficial and harmful bacteria. This challenges previous assumptions that such selective recognition was exclusive to vertebrates with adaptive immune systems. The study identified 'nematosomes' as key structures responsible for this discrimination, where they selectively engulf harmful bacteria while preserving the anemone’s natural microbiome. Researchers used CRISPR/Cas technology to disable the cJun gene, which reduced nematosome production and impaired the anemone’s ability to maintain a balanced microbiome, making them more vulnerable to infection.
