Vasopressin hormone linked to accelerated osteoarthritis in high blood pressure
A study conducted by researchers at Chonnam National University and Inje University has identified a biological mechanism linking high blood pressure to the acceleration of osteoarthritis.
Published in the journal Science, the research indicates that the brain hormone vasopressin plays a critical role. While vasopressin is produced in the brain and travels through the bloodstream to the joints, it specifically targets the AVPR1A receptor on cartilage cells. While this receptor is rarely found in healthy cartilage, it is significantly more prevalent in cartilage that has been damaged by mechanical stress or aging.
By analyzing data from the Korea National Health and Nutrition Examination Survey, researchers found that individuals with hypertension are more likely to suffer from osteoarthritis, with the severity of the joint disease correlating to blood pressure levels. These findings were further supported by mouse models, which demonstrated that high blood pressure leads to faster cartilage degradation.
