BPI fold containing family B, member 4 is a protein that in humans is encoded by the BPIFB4 gene.[5]
The study of many populations of centenarians made it possible to identify the longevity-associated variant (LAV) of the BPIFB4 gene.[6]
The gene transfer induced forced expression of LAV-BPIFB4 both in old mice and in animal model of hypertension reduced blood pressure and rescued age-related endothelial dysfunction stimulating endothelial nitric oxide synthase activation.[6]
As a gene associated with exceptional longevity, capable to protect from hypertension, atherosclerosis, diabetic cardiopathy, frailty, and inflammaging, LAV-BPIFB4 gene is a promising candidate new ‘drug’ to treat atherosclerosis, its cardiovascular complications, and neurodegenerative diseases.[7]
