Regulation of BAT thermogenesis via TRPA1-expressing hypothalamic POMC neurons.

ABSTRACT: Pro-opiomelanocortin (POMC) neurons in the hypothalamic arcuate nucleus (ARC) play a pivotal role in regulating brown adipose tissue (BAT) thermogenesis via the sympathetic nervous system. The activation of transient receptor potential ankyrin 1 (TRPA1) has been demonstrated to enhance heat production, particularly in BAT. However, no direct evidence has been reported regarding BAT thermogenesis mediated by TRPA1-regulated ARC POMC neurons. This study aimed to investigate the role of TRPA1-expressing hypothalamic POMC neurons in BAT thermogenesis. To confirm TRPA1 expression in ARC POMC neurons, we employed single-cell reverse transcriptase polymerase chain reaction and immunolabeling techniques. Selective TRPA1 agonists, including capsiate and ASP7663, induced depolarization of ARC POMC n
