By suppressing a single gene, scientists triggered the transformation of astrocytes into neurons in the mouse substantia nigra, where the converts released dopamine and connected with the striatum.
Compared with people who carry two copies of ApoE3 or ApoE4, ApoE2 homozygotes had an 87 and 99.6 percent lower risk for AD, respectively.
Alector’s AL002c antibody mobilizes microglia, reduces neuronal dystrophy, and restores normal behavior—all in mice. The clinical version is in Phase 1.
A mouse study claims that the small GTPase restrains pro-inflammatory responses in microglia. Aβ oligomers inhibit RhoA, promoting Aβ deposition and neurodegeneration.
At the at Tau2020 conference, scientists show high-resolution cryoEM of α-synuclein. Two different types of fibril are composed of asymmetric protofibril units.
Released from hippocampal neurons in response to experience, the cytokine prompted microglia to eat extracellular matrix around synapses. This facilitated growth of new spines, and sharpened memory.
This early marker distinguishes Alzheimer’s from controls and other neurodegenerative diseases more accurately than other biomarkers.
In large population datasets, people who had been vaccinated against influenza or pneumonia appeared less likely to develop AD.
Comprising mostly Aβ40, these large plaques are shot through with strange tubular structures and BBB markers. They are common in early onset AD.
Expert panel concludes there’s little risk based on current evidence.
AMX0035, a mix of sodium phenylbutyrate and taurursodiol, slowed functional decline over six months by about as much as the approved ALS drug edaravone.
Most pathways that emerged were common between African Americans and non-Hispanic whites, though some individual variants differed. Kidney development jumped out as a possibly unique aspect of AD in African Americans.
P-tau217 appears sooner than p-tau181 in the brain, and it distinguishes AD from controls and other dementias even more cleanly.
Researchers have devised a way to measure how long ago a reporter transcript was made. It allows them to detect distinct transcriptional events within a cell.
The transcription factor NFATc2 mediates this response.
