Blocking a receptor involved in inflammation in the brains of mice with severe Alzheimer’s produced marked recovery in blood flow and vascular reactivity, a dramatic reduction in toxic amyloid-beta, and significant improvements in learning and memory.
The receptor was the bradykinin B1 receptor (B1R), and the finding confirms a role of B1R, and neuroinflammation, in the development of Alzheimer’s. It also points to a new target for therapy.
