毒理性
brevetoxins 是一种神经毒素,能与神经细胞中的电压门控钠通道结合,导致正常神经过程受到干扰,临床上表现为神经性贝类中毒(NSP)。Brevetoxins 结合到电压敏感钠通道(VSSCs)的α亚基上的位点5,它们是细胞膜结构中的关键蛋白。据报道,与配体门控的上皮Na+通道相关的肺受体和巨噬细胞中的组织蛋白酶抑制会受到 brevetoxin 暴露的影响。(维基百科)
Brevetoxins are neurotoxins that bind to voltage-gated sodium channels in nerve cells, leading to disruption of normal neurological processes and causing the illness clinically described as neurotoxic shellfish poisoning (NSP). Brevetoxins bind to site 5 on the alpha-subunit of voltage sensitive sodium channels (VSSCs), which serve as key proteins in the structure of the cell membrane. Pulmonary receptors associated with ligand-gated epithelial Na+ channels and cathepsin inhibition in macrophages have been reported to be effected by brevetoxin exposure. (Wikipedia)
