Machine learning analysis of 912 PET scans says neurofibrillary tangles spread through the AD brain in one of four distinct patterns.
The L1CAM cell adhesion marker is a widely adopted marker of neuron-derived extracellular vesicles. Except it cannot be found in those teeny packets, claims a new study.
Instead of chewing up and disposing of the amyloid they ingest, microglia appear to compact it, then spit it back out as dense-core plaque.
A person's blood phospho-tau level, combined with his or her APOE genotype and scores on executive function and memory tests, outperforms the clinician in predicting dementia within the next four years.
The first whole-genome manipulation of protein expression in neurons by CRISPR reveals a deadly chain of events. Bad processing by lysosomes leads to build-up of lipids and iron. Oxidative stress revs up. Neurons die by ferroptosis.
In therapy-like paradigm, suppressing ApoE4 in astrocytes toned down tauopathy. This assuaged microglia, neurodegeneration, and revived nest-building.
In animals, polyamines such as spermidine enhance autophagy, rejuvenate mitochondria, and slow cognitive decline. Buzzword: hypusination. Human data not far behind.
A set of 19 plasma proteins identified clinical Alzheimer’s cases with 97 percent accuracy, and it distinguished mild versus severe dementia. The panel was tested in two small cohorts.
Both shy and funny, Allsop was a pioneer of modern Alzheimer's research.
African Americans are likelier than non-Hispanic Caucasians to carry low-expression TREM2 variants, and less likely to carry a high-expression variant. As a result, they have less soluble TREM2 in their cerebrospinal fluid.
People who develop Type 2 diabetes before age 60 have more than double the dementia risk, and earlier dementia onset, than those without diabetes.
The fewer their meningeal lymphatic vessels, the slower treated mice clear plaques. Lymphatic dysfunction also drives microglial activation, hinting at a role in pathology.
A “mammalian-wide interspersed repeat-natural antisense transcript” blocks translation of tau mRNA. Other MIR-NATS may act on α-synuclein and APP.
Via recently discovered channels, freshly made monocytes and B cells in the bone marrow of the skull and vertebrae travel directly into the meninges, where they stand ready to infiltrate the brain. These immune cells are distinct from their blood-borne counterparts.
