感官知觉调节老化和生理跨类群。我们发现,雌性性信息素的感知,通过一个特定的味觉受体表达在一个子集的前腿神经元在雄性果蝇,果蝇,迅速和可逆地减少脂肪储存,降低对饥饿的抵抗力,并限制寿命与神经元表达的奖励介导的神经肽F。高通量RNA-seq实验揭示了一组受长寿回路活动影响的分子过程,从而确定了新的候选细胞非自主衰老机制。交配扭转了信息素感知的影响,提出了一个模型,其中寿命是通过感官和奖励电路的整合调制,当感官知觉定义的期望与随后的经验不一致时,健康的老龄化可能会受到影响。
Sensory perception modulates aging and physiology across taxa. We found that perception of female sexual pheromones through a specific gustatory receptor expressed in a subset of foreleg neurons in male fruit flies, Drosophila melanogaster, rapidly and reversibly decreases fat stores, reduces resistance to starvation, and limits lifespan together with neurons that express the reward-mediating neuropeptide F. High-throughput RNA-seq experiments revealed a set of molecular processes that were impacted by the activity of the longevity circuit, thereby identifying new candidate cell non-autonomous aging mechanisms. Mating reversed the effects of pheromone perception, suggesting a model where lifespan is modulated through integration of sensory and reward circuits and where healthy aging may be compromised when the expectations defined by sensory perception are discordant with ensuing experience.
