NFKB1 and bacterial infectious disease: Thomas Gilmore (Boston University) focused on the dynamics of the NF-κB pathway during symbiont establishment in Aiptasia. Gilmore found that NF-κB signaling activity increases upon depletion of symbionts and decreases upon introduction of compatible symbionts to naïve Aiptasia. Symbiotic Aiptasia were more susceptible to pathogenic bacterium, which may explain why lower levels of bacterial infection were found in recently bleached corals.
