These Aβ deposits lead to subsequent molecular and cellular alterations, such as NTFs, neuronal dystrophy, or microgliosis, i.e., pathological events that are closer to dementia and more relevant to neuronal dysfunction. PubMed:29196815
In the hippocampal and cortical tissues of all AD cases examined, neuronal staining for ERα was a prominent finding, both with a weak cytoplasmic stain, but often specifically with a fibrillar appearance suggesting ERα was in neurofibrillary tangles (Fig. 1A), also shown at a higher magnification (Fig. 1B). PubMed:26837465
To confirm the localization of ERα in NFTs, double fluorescence staining with antibodies to ERα and hyperphosphorylated tau (PHF-1) revealed that ERα -positive NFTs were also positive for PHF-1 (Fig. 2A–F). PubMed:26837465
This result confirms previous findings that T231 is an important Cdc2 phosphorylation site in tau, and is also consistent with Pin1 binding mitotically pTau (Fig. 1a) and being sequestered on to PHFs in AD brains, where Cdc2 is upregulated (Fig. 3). PubMed:10391244
We also observed that tau and alpha-synuclein synergistically promote and propagate each other’s polymerization into fibrils PubMed:12714745
Recent studies of an individual with Parkinson’s disease (IX-47) of the Contursi kindred with the rare A53T alpha-synuclein mutation revealed widespread -syn and tau inclusions (15). Post-mortem examination of another affected member (IX-51) of this kindred also demonstrated abundant -syn and tau inclusions(figs. S1 and S2). Thus, a pathogenic mutation in alpha-synuclein that is known to increase the propensity of alpha-synuclein to fibrillize (8, 9) also promotes formation of tau inclusions in humans. PubMed:12714745

Additionally, it can induce phosphorylation of the tau protein and promote for- mation of neurofibrillary tangles through the mitogen activated protein kinases-p38 (MAPK-p38) stress pathway [22, 54]. PubMed:27314526

We found that in the visual cortex, neurons containing conspicuous quantities of mislocalized and aggregated tau nonetheless appear to have a normal capacity to integrate dendritic inputs and respond robustly to visual stimuli and also maintain normal somatic baseline calcium levels. In particular, we show that individual NFT-bearing neurons can respond robustly after integrating sensory inputs and are functionally indistinguishable from neighboring non–NFT-bearing neurons. These results demonstrate that NFT-bearing neurons remain functionally integrated in cortical circuits. PubMed:24368848
Dendritic arborization was abundant in RD3-/4+ pretangles, attenuated in RD3+/4+ neurons, and further attenuated in RD3+/4- ghost tangles. PubMed:23407988
