Cold exposure increases feeding, thermogenesis, and energy expenditure to maintain body temperature and energy balance, but the underlying neural mechanisms remain unclear. Here, we identify cold-responsive neurons in the dorsal posterior periventricular hypothalamus that coordinate these adaptations. Activation of GABAergic or cold-activated neurons increased food intake, body temperature, and brown adipose tissue thermogenesis, whereas their inhibition attenuated cold-induced hyperphagia and thermogenesis. Single-nucleus RNA sequencing identified Lef1 as a marker of cold-activated neurons in this region. Activation of Lef1+ neurons recapitulated key cold responses, whereas silencing attenuated them. Lef1 positively regulated Kcnk2, which encodes the cold-sensitive potassium channel TREK-1. Cold …
