Bee sting acupuncture protected osteoarthritic cartilage by activating a cellular regulator that suppresses inflammation, tissue breakdown, and cell death.
Researchers induced osteoarthritis in mice using a chemical joint injury model, then administered live bee stings at two traditional acupuncture points over several weeks. They assessed cartilage damage and blood markers, used computational target prediction and molecular docking to identify potential venom targets, measured inflammatory, matrix-degrading, and cell-death proteins in knee tissue, and examined gene activity and protein expression. They also tested bee venom in inflammatory cartilage cells while blocking the proposed regulatory pathway.
Bee sting acupuncture reduced cartilage pathology, inflammatory signalling, cartilage-matrix degradation, and cell-death activity while increasing protective cell-survival signalling. Gene and protein analyses indicated activation of peroxisome proliferator-activated receptor gamma, which appeared to restrain nuclear factor kappa B signalling; blocking this regulator weakened bee venom’s beneficial effects in cartilage cells.
