Alzheimer’s Disease (Deming, 2019)

WEEKLY UPDATE: August 22, 2019

STUDY TITLE: The MS4A gene cluster is a key modulator of soluble TREM2 and Alzheimer’s disease risk

SUMMARY: Identification of genetic variants that influence the risk of Alzheimer’s disease.

DESCRIPTION:  Alzheimer’s disease causes continual degeneration of the brain, which results in a variety of effects ranging from memory loss to personality change. Prior studies show that variants in the TREM2 gene can increase risk of Alzheimer’s disease. The TREM2 protein is found in the cerebrospinal fluid surrounding the brain and spinal cord. It plays an important role in activating the immune cells that help protect and repair our central nervous system. This study examined more than 800 individuals to confirm TREM2’s correlation with Alzheimer’s disease, specifically revealing that higher levels of the TREM2 protein can help protect against Alzheimer’s. Furthermore, this study discovered two variants in and near the MS4A4A gene that affect the production of TREM2. Scientists hope that these discoveries may provide a basis for developing therapies against Alzheimer’s disease.
