Verification of the findings from immunofluorescence microscopy was provided by Western blot analysis of hippocampal neuronal lysates with P404, P231 and P181 antiphosphotau antibodies. A 4 h exposure to 500nM ADDLs resulted in a significant increase in tau phosphorylated at the three epitopes, to levels similar to those observed after exposure to 10 M Abeta fibrils (Fig. 4A–D).

In support, tau associated with exosomes and phosphorylated at Thr-181 (AT270+ tau) has been identified in human CSF samples of AD patients PubMed:28420982
More recently, patients affected with FTD and AD, were found to have high levels of total tau and phosphorylated tau (p-T181 and p-S396; Saman et al., 2012) PubMed:28420982

Here, we show for the first time that the administration of D-ribose, the most active glycator among monosaccharides, produces high levels of advanced glycation end products (AGEs) and, importantly, triggers hyperphosphorylation of Tau in the brain of C57BL/6 mouse and neuroblastoma N2a cells.

Aβ 42 in the medium decreased in a GA dose-dependent manner (Fig. 3a). In contrast, GA significantly increased tau and its phosphorylated form, p-tauT181 (Fig. 3b,c) in the medium. In addition, VEGF (Fig. 3e) and TGF-β (Fig. 3f), which are also AD biomarkers, were increased when the concentration of GA added was greater than 0.7 mM. PubMed:26304819
Thus, our results suggest that Tau hyperphosphorylation was a result of ribosylated AGEs, rather than due to a direct reaction involving D-ribose. PubMed:28176663
Here, we found that prephosphorylation by PKA promotes GSK-3beta-catalyzed tau phosphorylation at Thr181, Ser199, Ser202, Thr205, Thr217, Thr231, Ser396 and Ser422, but inhibits its phosphorylation at Thr212 and Ser404. In contrast, the prephosphorylation had no significant effect on its subsequent phosphorylation by cdk5 at Thr181, Ser199, Thr205, Thr231 and Ser422; inhibited it at Ser202, Thr212, Thr217 and Ser404; and slightly promoted it at Ser396.
