Abstract Background Tau is a microtubule stabilizing protein and mainly expressed in neurons. aggregation into oligomers tangles considered an important pathological event tauopathies, such as frontotemporal dementia (FTD) Alzheimer’s disease (AD). Tauopathies are also associated with deficits synaptic plasticity long-term potentiation (LTP), but the specific role of tau manifestation these deficiencies not well-understood. We examined long lasting forms JNPL3 (BL6) mice expressing mutant that identified some inherited FTDs. Results found aged (>12 months) exhibit enhanced hippocampal late-phase (L-LTP), while young (age 6 displayed normal L-LTP. This L-LTP was rescued GABA A R agonist, zolpidem, suggesting loss GABAergic function. Indeed, we reduction interneurons. Finally, expression led to severe sensorimotor-gating hippocampus-dependent memory mice. Conclusions show for first time function impaired by protein, leading altered deficits. Increased understanding molecular mechanisms underlying failure AD FTD critical identifying targets therapies restore cognitive tauopathies.

Amyloid-beta (Aβ) and hyperphosphorylated tau are hallmark lesions of Alzheimer's disease (AD). However, the loss synapses dysfunctions neurotransmission more directly tied to severity. The role these in pathoetiological progression remains contested. Biochemical, cellular, molecular, pathological studies provided several lines evidence improved our understanding how Aβ accumulation may harm alter neurotransmission. In vitro suggests that have both direct indirect cytotoxic effects affect neurotransmission, axonal transport, signaling cascades, organelle function, immune response ways lead synaptic neurotransmitter release. Observations preclinical models autopsy support findings, suggesting while pathoetiology positive elusive, their removal reduce severity progression. purpose this article is highlight need for further investigation its interactions with neurotransmitters alike.

Traumatic brain injury (TBI) results in significant disability due to cognitive deficits particularly attention, learning and memory higher-order executive functions. The role of TBI chronic neurodegeneration the development neurodegenerative diseases including Alzheimer's disease (AD), Parkinson's (PD), Amyotrophic Lateral Sclerosis (ALS) most recently traumatic encephalopathy (CTE) is particular importance. However, despite effort very few therapeutic options exist prevent or reverse impairment following TBI. In this review we present experimental evidence known secondary mechanisms which contribute neuronal cell loss, axonal synaptic dysfunction hence both acutely chronically focus on linking two forms dementia: AD CTE. We provide potential molecular involved modulating Aβ Tau these pathology. Additionally propose a mechanism by generated as direct result capable exacerbating thereby establishing neurotoxic cascade that leads neurodegeneration.
