Abstract:
:Ecdysis triggering hormone receptors (ETHR) regulate the behavioral sequence necessary for cuticle shedding. Recent reports have documented functions for ETHR signaling in adult Drosophila melanogaster. In this study, we report that ETHR silencing in local interneurons of the antennal lobes and fruitless neurons leads to sharply increased rates of male-male courtship. RNAseq analysis of ETHR knockdown flies reveals differential expression of genes involved in axon guidance, courtship behavior and chemosensory functions. Our findings indicate an important role for ETHR in regulation of Drosophila courtship behavior through chemosensory processing in the antennal lobe.

杂志文章abstract::Stress is a known inhibitor of reproductive function. The mechanisms by which stress acts to influence the reproductive axis have been intensely studied and appear to be extremely varied.
