Tau Modifications Sections of NESTOR

By acting on the α7 receptors in glutamate terminals, acutely administrated nicotine stimu- lates the release of glutamate, which facilitates the burst fir- ing of VTA DA neurons and eventually leads to LTP,and increases the firing rate of the GABAergic neurons of the rostromedial tegmental nucleus PubMed:28901280

Chronic nicotine treatment also activates the α7 receptors expressed on glutamatergic terminals, increases the release of glutamate (which facilitates the burst firing of VTA DA neurons), increases NMDA receptor activity, and LTP [79], but simultaneosusly induces the desensitisation of the α4β2 receptors on GABAergic terminals. Overall, these effects decrease the inhibition onto DA neurons, and increase DA release in the NAc [82]. PubMed:28901280

Furthermore, extracellular oligomeric tau impairs memory and long-term potentiation (LTP) in mice PubMed:29238289

Here we report abnormal acetylation of K274 and K281 on tau, identified in AD brains, promotes memory loss and disrupts synaptic plasticity by reducing postsynaptic KIdney/BRAin (KIBRA) protein, a memory-associated protein.Transgenic mice expressing human tau with lysine-to-glutamine mutations to mimic K274 and K281 acetylation (tauKQ) exhibit AD-related memory deficits and impaired hippocampal long-term potentiation (LTP). TauKQ reduces synaptic KIBRA levels and disrupts activity-induced postsynaptic actin remodeling and AMPA receptor insertion. The LTP deficit was rescued by promoting actin polymerization or by KIBRA expression. In AD patients with dementia, we found enhanced tau acetylation is linked to loss of KIBRA. PubMed:27041503

These findings suggest that CaMKv is required for both synaptic transmission and protein synthesis-dependent LTP in the hippocampus. PubMed:27796283
