Mosquito Aedes aegypti (L.) leucokinin receptor is critical for in vivo fluid excretion post blood feeding

[摘要]：The evolution of the blood feeding adaptation in mosquitoes required hormonal coordination of multiple physiological processes (behavior, digestion, diuresis, oogenesis). The Aedes kinins (leucokinin-like neuropeptides) are involved in post blood feeding physiological processes, having diuretic and myotropic functions. To understand the in vivo contribution of the kinin receptor to overall female post-prandial fluid excretion, RNAi knockdown was followed by fluid secretion assays which proved its fundamental role in rapid diuresis. The Aedes kinin receptor was also localized in several tissues not previously reported in mosquitoes. Results highlight the integrative role of the Aedes kinins in the success of the blood feeding adaptation. (C) 2011 Federation of European Biochemical Societies. Published by Elsevier B.V.
