Using mass spectrometry to detect teensy amounts of phospho-tau species in plasma, researchers reported that p-tau-217 and p-tau-181 picked out people with Aβ pathology. Differences between groups appear to be huge. An MS-based test for plasma Aβ42 corresponded to brain amyloid, and is going in for regulatory approval.
Biogen researchers claim the antibody worked in people who got enough of it. To other researchers, the signal validates the amyloid hypothesis and injects fresh energy into the field. But is this interrupted dataset enough to approve?
Prior research has focused on microglia interacting with synapses. New data show they also deal directly with the neuronal cell body. Like little conference rooms, specialized junctions host this communication.

Researchers link age-related weakening of the barrier to TGFβ signaling, hyperexcitation, and cognitive problems. In rodents, TGFβ antagonists attenuate these effects, reducing seizures.

As gene therapy is making a comeback, scientists are exploring if it might prevent or reverse Alzheimer’s. Some of those treatments are permanent, heightening safety concerns.
Encouraged by success in treating infant spinomuscular atrophy, researchers are redoubling their efforts to target genetic causes of age-related neurodegeneration.
