AI Insight
Researchers at King Abdullah University of Science and Technology (KAUST) have discovered that corals can develop immune-like protection against pathogens when exposed to controlled, low-level doses of dead pathogenic cells. This "vaccine-like" response enables corals to better resist subsequent infections from the same pathogens. The finding demonstrates that corals possess a form of immune priming or memory, similar to vaccination mechanisms in other organisms.
Why it matters
This research could provide a practical tool for protecting coral reefs, which face increasing threats from disease outbreaks exacerbated by rising ocean temperatures due to climate change. The technique may allow marine conservationists to boost coral immunity and resilience before disease events occur, potentially helping to preserve these critical ecosystems.
Understand the Science
To boost corals’ resilience amid rising sea temperatures and the spread of disease, KAUST researchers have found that controlled, low-level exposure to dead pathogenic cells can help corals resist future infection.
