The enzyme degrades anti-inflammatory fatty acids in the brain. Blocking it with a brain-penetrant small molecule calmed A1 astrocytes, synapse-eating microglia, and improved amyloidosis and cognition in a mouse model.
Plaque-ridden 5xFAD mice were no better at fending off an intracerebral herpes virus infection than their wild-type counterparts. The virus was not to be found within Aβ plaques and did not spur plaques to form.
In mouse brain slices at least, tau shuffles in and out of protein inclusions. The tangles grew more inert as the tissue aged.
When cultured with human neurons expressing a familial Alzheimer’s gene, both microglia and astrocytes were necessary to spike complement C3 and send inflammation into overdrive.
By comparing protein changes with GWAS data, scientists identified new links to AD. This method can unearth genes that otherwise fall short of genome-wide significance.
In mouse models of Aβ toxicity and amyloidosis, inhibiting the integrated stress response restored protein production, spared synapses, and brought back memory.
Plaques abound, cytokines spike, microglia swell with lipids and send out spermine SOS signals in Denali model. Mice will be shared, allowing unrestricted use.
In mice, an anti-ApoE antibody removed plaques from the brain’s parenchyma and blood vessels better than aducanumab. Importantly, it caused no microhemorrhages.
Centenarians who scored high on the MMSE stayed cognitively and physically active over the next two years, even if they carried genetic risk factors for Alzheimer’s. What protects these lucky few?
The slowdown of proteasomes stymied TDP-43’s entry into the nucleus and promoted its aggregation in the cytoplasm.
Massive meta-analysis finds the longevity gene’s VS haplotype staves off mild cognitive impairment and AD. It reduces amyloid burden.
This update of the Allen Brain Institute atlas reveals detailed anatomical structures and provides a common framework for comparing brain datasets.
Separately, cerebrovascular disease drove an uptick in neurofilament light in the brain, indicating neurodegeneration.
The plasma biomarker neurofilament light was able to distinguish individual mutation carriers from noncarriers three years prior to onset.
Researchers identify a way to isolate human astrocytes generated from induced pluripotent stem cells. And astrocytes stand out in FTD-prone brain areas.
