The innate immune system uses pattern recognition receptors such as RIG-I and
NLRP3 to sense pathogen invasion and other danger signals. Activation of these
receptors induces robust signal transduction cascades that trigger the production
of cytokines important for host protection. MAVS and ASC are essential adaptor
proteins downstream of RIG-I and NLRP3, respectively, and both contain N-terminal
domains belonging to the death domain superfamily. Recent studies suggest that
both MAVS and ASC form functional prion-like fibers through their respective
death domains to propagate downstream signaling. Here, we review these findings,
and in this context discuss the emerging concept of prion-like polymerization in
signal transduction. We further examine the potential benefits of this signaling
strategy, including signal amplification, host evolutionary advantage, and
molecular memory.
