IFNA13 (Interferon Alpha 13): IFNA13 is a cytokine from the interferon alpha family, which plays a key role in immune defense against viral infections and tumor growth. It activates the innate immune system, triggering genes that block viral replication, boost cell-mediated immunity, and promote the apoptosis of infected or cancerous cells. Its functions in antiviral defense and cancer immunotherapy underscore its importance in immune regulation and anti-tumor activity.
