毒理性

• 毒性总结

震颤原性真菌毒素通过干扰神经递质的释放来发挥其毒性作用，可能是通过导致神经末梢的变性。它们被认为可以抑制γ-氨基丁酸（GABA）受体，包括突触前和突触后的受体，同时还可以抑制GABA-T受体上的递质分解。这最初会增加神经递质的水平，增强GABA诱导的氯离子电流，然后导致突触中神经递质水平的降低。此外，高粱素可以抑制平滑肌中突触前的高电导钙激活大K+通道。（A2976, A2993）

Tremorgenic mycotoxins exert their toxic effects by interfering with neurotransmitter release, possibly by causing degeneration of nerve terminals. They are thought to inhibit gamma-aminobutyric acid (GABA) receptors, both pre- and postsynaptic, as well as inhibit transmitter breakdown at the GABA-T receptors. This would initially increase neurotransmitter levels, potentiating the GABA-induced chloride current, then lead to decreased levels of neurotransmitter in the synapse. In addition, paspalinine inhibits presynaptic high-conductance Ca+2 activated maxi-K+ channels in the smooth muscle. (A2976, A2993)

震颤原真菌毒素影响中枢神经系统活动，引起包括精神混乱、瘫痪、震颤、癫痫和死亡在内的神经症状。它们导致牛患有一种被称为“蹒跚综合症”的神经疾病，其特征是肌肉震颤、过度兴奋、惊厥和共济失调。

Tremorgenic mycotoxins affect central nervous system activity, inducing neurologic symptoms including mental confusion, paralysis, tremors, seizures, and death. They cause a neurological disease of cattle known as "staggers syndrome", which is characterized by muscle tremors, hyperexcitability, convulsions and ataxia. (A2976)
