Breakthrough Research Provides Valuable Insight On Cause Of Alzheimer’s
Date:1/8/2014

New York, NY (PRWEB) January 08, 2014

A stem cell model of familial Alzheimer’s disease (FAD) was successfully generated, allowing researchers to identify 14 genes potentially implicated in the disease. One gene in particular demonstrates the important role inflammation may play in the brain of Alzheimer’s patients. The study was completed by scientists at The New York Stem Cell Foundation (NYSCF) Research Institute in collaboration with scientists at the Icahn School of Medicine at Mount Sinai (ISMMS) and funded in part by the Cure Alzheimer’s Fund(CAF).

In the study published today in PLOS ONE, a team of scientists produced stem cells and neural precursor cells (NPCs), representing early neural progenitor cells that build the brain from patients with severe early-onset AD with mutations in the Presenilin 1 (PSEN1) gene. These NPCs had elevated Abeta42/Abeta40 ratios, indicating elevation of the form of amyloid found in the brains of Alzheimer’s patients. These levels were greater than those in adult cells that did not have the PSEN1 mutation. This elevated ratio shows that the NPCs grown in the petri dish accurately reflected the cells in the brains of FAD patients.

"The gene expression profile from the familial Alzheimer’s stem cells points to inflammation, which is especially exciting because we would not usually associate inflammation with this particular Alzheimer's gene," said Sam Gandy, MD, PhD, Professor of Neurology and Psychiatry and Director of the Center for Cognitive Health at the Icahn School of Medicine at Mount Sinai and a co-author on the study. Gandy is also Associate Director of the NIH-Designated Mount Sinai Alzheimer’s Disease Research Center and leader of the
