TREM2 tagged posts

New insights into the mechanisms of neurodegenerative diseases. Findings by researchers from Germany support the view that hyperactive immune cells in the brain can have a protective effect in the course of neurodegenerative diseases. Experts from Deutsches Zentrum für Neurodegenerative Erkrankungen (DZNE), Ludwig-Maximilians-Universität München (LMU) and LMU Klinikum München report on this in the scientific magazine The EMBO Journal. The scientists are currently considering that modulating the activity of immune cells in the brain via a receptor called TREM2 may significantly impact neurodegenerative disease processes. Thus, they see activating TREM2 as a promising approach for drug research.

The immune cells of the brain — called “microglia” — act against pathogens, help to c...

sTREM2 cerebrospinal fluid levels are a potential biomarker for microglia activity in early-stage Alzheimer’s Disease and associate with neuronal injury markers

This secreted marker molecule, which can be measured from CSF taps, may provide clinicians with a rapidly detectable biomarker for the transition from preclinical Alzheimer’s disease to cognitive impairment and progression to full dementia. Such is the conclusion of a multi-center study on a large group of human patients, published online in EMBO Molecular Medicine.

Alzheimer’s disease, an increasing problem in today’s aging populations, is characterized by amyloid peptide plaques and tau protein aggregates in nerve cells...
