An article published in Brain is interesting. A new gene for further research and study.
Highlight from the article:
The new study builds on previous work by the UCL team that reported a link between oligoadenylate synthetase 1 (OAS1) and Alzheimer's disease. The OAS1 gene is expressed in microglia, an immune cell that accounts for ~10–15% of the cells found in the brain. While the hallmark of Alzheimer's disease pathology is a build-up of amyloid plaques and TAU tangles in the brain, a growing body of research is demonstrating how the immune system – and in particular, inflammation – contributes.
In a genome wide association study (GWAS) of 2,547 people – 50% of which had Alzheimer's disease – Salih and colleagues identified a variant of the OAS1 gene, known as rs1131454, that was linked to an increased likelihood of having the disease.
