Prion-Like Polymerization in Immunity and Inflammation

The innate immune system relies on receptors that sense common signs of infection to trigger a robust host-defense response. Receptors such as RIG-I and NLRP3 activate downstream adaptors mitochondrial antiviral signaling (MAVS) and apoptosis-associated speck-like protein (ASC), respectively, to propagate immune and inflammatory signaling. Recent studies have indicated that both MAVS and ASC form functional prion-like polymers to propagate...
