A Phosphorylated Tau Species Is Transiently Present in Developing Cortical Neurons and Is Not Assocfrom the deepest cortical layers where neurons are onto-genetically the oldest. This phosphorylated tau was found in axons and dendrites of cortical neurons at all developmental stages, whereas unphosphorylated tau tended to disappear from dendrites during development. The timing of appearance of ph大厅 发表于 2025-3-29 00:25:32
Modifications of Phosphorylated Tau Immunoreactivity Linked to Excitotoxicity in Neuronal Cultures,l 1991; Mattson et al. 1992). Glutamate is also able to produce an intracellular signal transduction into neurons leading to protein phosphorylations (Scholz and Palfrey 1991). Tau is a microtubule-associated protein which favours microtubule polymerisation and stabilisation (Kosik 1993). One of theconsiderable 发表于 2025-3-29 04:16:34

Since such accumulation is seen both in sporadic and familial ALS, it is almost certain to be a key intermediate in the pathway of pathogenesis leadiAnalogy 发表于 2025-3-29 10:32:16

Amyloid ,-Peptide Induces Necrotic Cell Death in PC12 Cells,t of oxidative stress (Behl et al. 1992), although the two may be linked. The cytotoxicity of A.P 1–40 has been associated with a fragment including residues 25–35 (Yankner et al. 1990). This study aimed at determining the mechanism of this .25–35 induced cytotoxicity and distinguishing between eith暂时休息 发表于 2025-3-29 16:55:51
