查询词典 tubular membranes

Ultimately, vulnerable groups of neurons atrophy and die in a process that may involve excitotoxicity (overstimulation of neurotransmitter receptors on neuronal surface membranes), collapse of calcium homeostasis, inflammation, and depletion of energy and growth factors. A form of apolipoprotein E, apoE4, contributes to the abnormal accumulation of A and tau, but probably also damages mitochondria and the cellular cytoskeleton. A , tau, apoE and -synuclein interact with many other molecules and modulate diverse signalling cascades that regulate neuronal activity and survival.

最后，易感神经元会萎缩直至死亡，原因可能有兴奋性中毒（神经递质对神经元表面受体的过度刺激引起），钙稳态失衡，炎症反应，能量和生长因子的耗尽。apoE4的产生可导致A肽和tau蛋白的异常聚合，可能也损害线粒体和细胞骨架。A肽、tau蛋白、apoE和突触核蛋白可与很多分子反应，也可调节不同信号级联反应，这些级联反应对于维持神经元活动性和生存性意义重大。
