Denosumab mimics the action of osteoprotegerin (OPG) by binding to which target?
Show answer and explanation
Correct answer: RANKL (Receptor Activator of Nuclear Factor kappa-B Ligand)
Denosumab binds to RANKL, preventing it from activating the RANK receptor on osteoclast precursors. This inhibits osteoclast formation and function, thereby decreasing bone resorption in conditions like osteoporosis.
