Whether a person eats a cookie or devours the whole box could come down to the mood of microglia in their hypothalamus. Blocking activation of the region’s NLRP3 inflammasome could keep excessive ...

For people with cerebral amyloid angiopathy (CAA), the heightened risk of ARIA, i.e., inflammation around blood vessels, may outweigh any potential gains of anti-amyloid immunotherapy. But with about ...

Could stem cells step in to replace lost neurons in Parkinson’s disease? In three Phase 1 clinical trials, scientists tested lab-grown dopaminergic cells in small cohorts to assess safety and look for ...

In the Alzheimer’s brain, microglia diversify into several activation states. What controls this specialization? In a preprint posted to bioRxiv on October 13, scientists led by Martin Kampmann at the ...

Retrotransposons are evolutionarily ancient genes that “jump” around the human genome leaving a slew of repeat nucleotide sequences in their wake. These repeats can disturb normal gene function.

Dozens of rodents have been generated that model various aspects of ALS, like motor impairment or degeneration of motor neurons. No model recapitulates the human disease perfectly. By organizing ...

Biogen’s hopes for a quick regulatory approval of its anti-Aβ antibody aducanumab may be dimming. An advisory panel convened by the U.S. Food and Drug Administration was unimpressed by the evidence ...

On Tuesday September 10, Francisco Lopera died of cancer at his home in Medellin, Colombia. He was 73, and only just beginning to see his life’s work come to fruition. In fact, Lopera still had much ...

The slight slowing of cognitive decline achieved by Leqembi and perhaps by Aduhelm has revived debate around how much change is needed to be “clinically meaningful.” Two recent papers—one a report ...

Buoyed by data crediting amyloid removal with ever-so-slightly slowed cognitive decline, many scientists are now optimistic about the prospects for anti-amyloid immunotherapy. Four “-mabs”—of the ...

A paper in the September 21 Journal of Neuroscience suggests that two prominent phenotypes considered relevant to Alzheimer’s disease are artifacts caused by overexpression of the amyloid precursor ...

Against classical music and visual backdrops evoking Vienna, where the second AAT-AD/PD conference was to be held, the meeting instead unfolded Netflix-style. In this surreal age of COVID-19, the ...
