演題:Modulation and intracellular regulation of insect nicotinic acetylcholine receptors
演者:Professor Steeve H. Thany (University of Orleans)
フランスのオルレアン大学から教授を招き、ネオニコチノイド殺虫剤がどうして効くかについて話していただきます。初歩的なところから話していただきますので、是非ご来聴ください。
Insect neurosecretory cells, called dorsal unpaired median neurons, are known to express two α-bungarotoxin-insensitive nicotinic acetylcholine receptor (nAChR) subtypes, nAChR1 and nAChR2 which are differently sensitive to neonicotinoid insecticides.
We suggested that their sensitivity to neonicotinoids could be associated to their intracellular regulation mechanisms. Unfortunately, the intracellular mechanisms leading to the regulation of insect nAChRs are unknown.
We demonstrated for the first time that nAChR1 was sensitive to cAMP/cAMP-dependent protein kinase (PKA) regulation, resulting in a modulation of nicotine currents. (続く)
