Abstract

Tau vaccination and administration of anti-tau antibodies can prevent pathology and cognitive impairment in transgenic mouse models of tauopathy, suggesting that therapies which increase anti-tau antibodies might slow the development and/or progression of Alzheimer's disease (AD). The extent to which individuals with no cognitive impairment (NCI) possess serum anti-tau antibodies, and whether their concentrations of these antibodies differ from anti-tau antibody levels in persons with mild cognitive impairment (MCI) or AD, are unclear. Previous studies measuring these antibodies did not account for antibody polyvalent binding, which can be extensive, nor that antibody binding to phosphorylated tau peptides could be due to binding to non-phosphorylated epitopes on those peptides. An ELISA controlling for these factors was used to measure the specific binding of serum IgG and IgM to phosphorylated ("pTau;" phosphorylated at Serine-199 and Serine-202) and non-phosphorylated ("non-pTau") tau 196-207 in subjects with NCI, MCI, or AD (n = 10/group). Between-group differences in these antibody levels were evaluated for statistical significance, and correlations were examined in pooled data from all subjects between these antibody levels and subject age, global cognitive functioning, and NFT counts. Specific IgG binding to pTau and non-pTau was detected in all subjects except for one NCI control. Specific IgM binding was detected to pTau in all subjects except for two AD patients, and to non-pTau in all subjects. Mean pTau IgG was increased in MCI subjects by 53% and 70% vs. AD and NCI subjects respectively (both p < 0.05), while no significant differences were found between groups for non-pTau IgG (p = 0.052), pTau IgM, or non-pTau IgM. Non-pTau IgG was negatively associated with global cognition (Spearman rho = -0.50). Specific binding of serum IgG and IgM to phosphorylated and non-phosphorylated tau may be present in older persons regardless of their cognitive status. Serum IgG to phosphorylated tau may be increased in individuals with MCI, but this unexpected finding requires confirmation. The approach used in this study to measure specific serum antibodies to phosphorylated tau should be useful for measuring antibodies to other post-translationally-modified proteins that are of relevance to neurodegenerative disorders.

Attention Score in Context

Attention Score in Context

This research output has an Altmetric Attention Score of 3. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 17 March 2022.
All research outputs
#8,537,346
of 25,382,440 outputs
Outputs from Translational Neurodegeneration
#296
of 384 outputs
Outputs of similar age
#157,022
of 446,214 outputs
Outputs of similar age from Translational Neurodegeneration
#3
of 5 outputs
Altmetric has tracked 25,382,440 research outputs across all sources so far. This one is in the 43rd percentile – i.e., 43% of other outputs scored the same or lower than it.
So far Altmetric has tracked 384 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 29.7. This one is in the 21st percentile – i.e., 21% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 446,214 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 52% of its contemporaries.
We're also able to compare this research output to 5 others from the same source and published within six weeks on either side of this one. This one has scored higher than 2 of them.
