Neuronal regulation of longevity by staying cool

Aging is fundamental to life and reflects functional declines in different tissues at the organismal level. As a systematic process, aging can be influenced by the interplay between genetic and environmental factors, and the nervous system plays a crucial role in this regulation. Environmental inputs can be sensed by the nervous system, which consequently triggers signaling outputs toward peripheral tissues to regulate gene expression systematically. Thus, understanding the underlying molecular mechanisms behind environmentally triggered neuron–periphery cross-talk is crucial for the promotion of an organism's health and longevity.
