Since microglia play a critical role in resolving amyloid pathology and it has been previously demonstrated that microglia function can be induced by TREM2 activation, TREM2 agonism has been considered a promising novel therapeutic approach to delay or prevent the progression of Alzheimer’s disease.

At the 2024 Alzheimer’s & Parkinson’s Diseases Conference this week, Michel Goedert from the MRC Laboratory of Molecular Biology in Cambridge gave the Donald L. Price Memorial Plenary Lecture entitled, “Cryo-EM structures of disease filaments from human brains.” Donald Price was particularly well-known for his work on plaques and tangles in nonhuman aged primate brains and for the development of several animal models of neurodegenerative diseases.

Neurocode USA Inc. added Alzpath Dx, a blood test for Alzheimer’s disease screening, to its lab developed tests, making it the first available for commercial use in the U.S. The move stands to make screening for the neurodegenerative disease much more accessible, as recent study results indicate Alzpath’s accuracy rivals PET scans and cerebrospinal fluid tests, the current gold standards, in detecting the signature biomarkers of the disease.

Biovie Inc.’s double-barrelled blast of positive data with insulin sensitizer NE-3107 in Alzheimer’s disease (AD) and Parkinson’s disease (PD) launched shares (NASDAQ:BIVI) on a wild ride to close March 1 at $2.23, up 99 cents, or almost 80%, after trading as high as $3.31.

Separate teams of investigators have reported new insights into how the brain disposes of metabolic waste via the glia-based lymphatic system, or glymph system. In two papers published in Nature on Feb. 28, 2024, scientists from Washington University in St. Louis described how in sleeping animals, the synchronized activity of neurons drove ionic gradients that facilitated the movement of fluid through brain tissue. And researchers from the Massachusetts Institute of Technology showed that, in a mouse model of Alzheimer’s disease (AD), the glymphatic system mediated clearance of amyloid-β after sensory stimulation at a 40-Hertz rhythm.

With the number of people with dementia in Australia expected to nearly double by 2054, the federal government is funding a new AU$50 million (US$32.76 million) biomedical and med-tech incubator program to develop new therapies, medical devices and digital health technologies to address dementia and cognitive decline.
