ABSTRACT
Osteoporosis, a disease characterized by low bone mass and deterioration of bone tissue, is a pressing public health problem. Recent studies have suggested a possible role of T-helper (Th) cells in the pathogenesis of bone loss which occurs in systemic inflammatory diseases. However, there are contradictions in the published literature regarding the functional role of Th1/Th2 cells in the regulation of the differentiation of osteoclasts. These paradoxes have now been clarified by the recent discovery of Th17 cells, a novel subset of Th cells that selectively secrete several proinflammatory cytokines, mainly IL-17. It has been confirmed that Th17 cells have stimulatory effects on osteoclastogenesis and accelerate bone loss in animal models with inflammatory disorders. Targeting Th17 cells or IL-17 may inhibit the bone resorption with RA. Thus, we are led to suppose that Th17 cells might be promising therapeutic targets in osteoporosis.
