SIGIRR plays a dual role in zebrafish infected with Edwardsiella piscicida: Boosting digestive system wellness and mitigating inflammation.

Single immunoglobulin interleukin-1 receptor-associated protein (SIGIRR) negatively regulates the inflammatory response induced by bacterial infection by inhibiting the excessive synthesis of inflammatory mediators and overactivation. This inhibitory mechanism reduces the fish's susceptibility to pathogens and enhances survival rates. Zebrafish lacking the SIGIRR gene were generated using CRISPR/Cas9 gene knockout technology.
