Thermoregulation is one of the most vital functions of the brain, but how
temperature information is converted into homeostatic responses remains unknown.
Here, we use an unbiased approach for activity-dependent RNA sequencing to
identify warm-sensitive neurons (WSNs) within the preoptic hypothalamus that
orchestrate the homeostatic response to heat. We show that these WSNs are
molecularly defined by co-expression of the neuropeptides BDNF and PACAP. Optical
recordings in awake, behaving mice reveal that these neurons are selectively
activated by environmental warmth. Optogenetic excitation of WSNs triggers rapid
hypothermia, mediated by reciprocal changes in heat production and loss, as well
as dramatic cold-seeking behavior. Projection-specific manipulations demonstrate
that these distinct effectors are controlled by anatomically segregated pathways.
These findings reveal a molecularly defined cell type that coordinates the
diverse behavioral and autonomic responses to heat. Identification of these
warm-sensitive cells provides genetic access to the core neural circuit
regulating the body temperature of mammals. PAPERCLIP.
