RIG-1 modulator 1 is primarily used in research focused on enhancing the innate immune response. It works by activating the RIG-I pathway, which plays a crucial role in detecting viral RNA and initiating antiviral defenses. This makes it a valuable tool in studying antiviral mechanisms and developing potential treatments for viral infections. Additionally, it is explored in cancer immunotherapy, as activating RIG-I can stimulate immune cells to target and destroy cancer cells. Its application extends to understanding autoimmune diseases, where modulating RIG-I signaling could help regulate overactive immune responses.
