在沙夫纳按蚊(Anoplius safnariensis)的毒液中发现了一种新的神经毒素,命名为α-pompilidotoxin(α-PMTX)。α-PMTX(10-100 μM)可显著增强龙虾步行腿神经肌肉突触的兴奋性和抑制性突触后电位。在突触部位记录兴奋性突触后电流(EPSC)表明α-PMTX可逆地和剂量依赖性地增强EPSC。α-PMTX可能主要作用于突触前膜,但该毒素的作用方式明显不同于其他已知的易化神经毒素,如α-latrotoxin、apamin或charybdotoxin。这种新的毒素将作为一个有用的工具,在神经科学的研究领域。
A new neurotoxin, named α-pompilidotoxin (α-PMTX) has been found in the venom of the solitary wasp Anoplius safnariensis. In the neuromuscular synapse of the lobster walking leg preparation, α-PMTX (10-100 μM) caused great enhancement of both the excitatory and inhibitory postsynaptic potentials. Recordings of the excitatory post synaptic currents (EPSCs) at the synaptic sites showed that α-PMTX reversibly and dose-dependently potentiates EPSCs. α-PMTX may act primarily on the presynaptic membrane but the mode of action of the toxin is clearly different from other known facilitatory neurotoxins, such as α-latrotoxin, apamin or charybdotoxin. This novel toxin will serve as a useful tool in the research field of neuroscience.
