Now online! IL-1R1-positive dorsal raphe neurons drive self-imposed social withdrawal in sickness
During sickness, animals exhibit prolonged social withdrawal, a response that may limit disease spread. Elevated IL-1β levels during inflammation activate IL-1R1-expressing neurons in the dorsal raphe nucleus to drive self-imposed withdrawal, highlighting a neural mechanism through which immune activation reconfigures social behavior.
