Abstract
Amyloid-β plaque accumulation in Alzheimer's disease (AD) is associated with dystrophic neurite (DN) formation and synapse loss in principal neurons, but interneuron pathology is less clearly characterized. We compared the responses of neuronal processes immunoreactive for either neurofilament triplet (NF(+)) or calretinin (CR(+)) to fibrillar amyloid (Aβ) plaques in human end-stage and preclinical AD, as well as in APP/PS1 and Tg2576 transgenic mouse AD models. Neurites traversing the Aβ plaque core, edge, or periphery, defined as 50, 100, and 150% of the plaque diameter, respectively, in human AD and transgenic mouse tissue were compared to age-matched human and wild-type mouse controls. The proportion of NF(+) neurites exhibiting dystrophic morphology (DN) was significantly larger than the proportion of dystrophic CR(+) neurites in both human AD and transgenic mice (p < 0.01). Additionally, the number of NF(+), but not CR(+), DNs, correlated with Aβ plaque size. We conclude that CR(+) interneurons appear to be more resistant than NF(+) neurons to AD-mediated cytoskeletal pathology.
This research output has an Altmetric Attention Score of 1. 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 26 September 2013.
All research outputs
#18,348,542
of 22,723,682 outputs
Outputs from Frontiers in Neuroanatomy
#918
of 1,157 outputs
Outputs of similar age
#218,065
of 280,763 outputs
Outputs of similar age from Frontiers in Neuroanatomy
#21
of 31 outputs
Altmetric has tracked 22,723,682 research outputs across all sources so far. This one is in the 11th percentile – i.e., 11% of other outputs scored the same or lower than it.
So far Altmetric has tracked 1,157 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 8.9. This one is in the 13th percentile – i.e., 13% 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 280,763 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 11th percentile – i.e., 11% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 31 others from the same source and published within six weeks on either side of this one. This one is in the 19th percentile – i.e., 19% of its contemporaries scored the same or lower than it.
