Consortium to investigate role of neurofilament light chain in neurodegenerative diseases

Clinical scientists at Washington University School of Medicine in St. Louis and University College London are collaborating with pharmaceutical companies AbbVie, Biogen, Bristol Myers Squibb and Roche to investigate the role of neurofilament light (NfL) chain in neurodegenerative diseases such as amyotrophic lateral sclerosis, Parkinson’s disease, Huntington’s disease and Alzheimer’s disease. NfL is a protein that provides structural support to […]

Alzheimer's Disease Causes

The exact cause of Alzheimer’s disease is not clearly understood, but patients with the condition have been found to have abnormal protein deposits (amyloid plaques) in their brains, along with fibres called tau tangles and a chemical called acetylcholine. These disrupt neuronal messaging in the brain, which eventually becomes permanently damaged, affecting memory and cognitive processing. Although the exact triggers […]
