Artificial intelligence learns to recognize subtle biochemical features of γ-secretase substrates. Screening potential transmembrane proteins identifies 250 substrates, including 160 novel ones. These ...

Nowadays, in the hunt for biomarkers of Alzheimer’s and related diseases, blood is where it’s at. Blood draws are cheaper and easier than other options, and clinical trial participants prefer them, ...

Signaling through the TREM2 receptor fuels an ever-growing list of known microglial functions in the brain, and gene variants that hobble TREM2 signaling beckon Alzheimer’s disease. Ergo, activating ...

Over the last 40 years, age-adjusted dementia prevalence in the U.S. has dropped by two-thirds. This predicts a 25 percent rise in total dementia cases by 2050, due to population aging. The findings ...

Inhaled xenon shifts microglia from a pro-inflammatory to a phagocytic state. Interferon-γ released by peripheral T cells flips the switch. In mice, xenon curbed plaques and dystrophic neurites. A ...

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 ...

A new multiplex diagnostic method appears poised to resculpt the biomarker landscape. NULISA, aka NUcleic acid Linked Immunosorbent Assay, can detect Aβ peptides, p-tau isoforms, and other potential ...

Crafting a PET tracer to detect α-synuclein deposits in the brain has been an uphill struggle. Now, scientists led by Hironobu Endo and Makoto Higuchi at the National Institutes for Quantum Science ...

For 30 years, APOE4 has ranked as the strongest genetic risk factor for Alzheimer’s disease, with two copies boosting the odds up to 15-fold. Now, scientists argue that people with two APOE4 alleles ...

Old drugs die hard. Despite a string of negative Phase 3 trials, HMTM, a derivative of the malaria drug methylene blue, resurfaced again at AD/PD 2024, held March 5-9 in Lisbon, Portugal. TauRx CEO ...

Part 2 of 2. Click here for Part 1. What happens in the brain of a person with fatal ARIA? Researchers now have one of their first detailed looks at the pathology of this rare and calamitous condition ...

Scientists reported results of a round-robin comparison of more than two dozen plasma phospho-tau assays. (Hint: p-tau 217 tests outdid the rest of the flock.) A clearer picture emerged of how plasma ...
