Abstract
Bone regeneration is a tightly regulated process that ensures proper repair and functionality after injury. The delicate balance between bone formation and resorption is governed by cytokines and signaling molecules released during the inflammatory response. Interleukin (IL)-17A, produced in the early phase of inflammation, influences the fate of osteoprogenitors. Due to their inherent capacity to differentiate into osteoblasts, mesenchymal stem/stromal cells (MSCs) contribute to bone healing and regeneration. This review presents an overview of IL-17A signaling and the leading cellular and molecular mechanisms by which it regulates the osteogenic differentiation of MSCs. The main findings demonstrating IL-17A’s influence on osteoblastogenesis are described. To this end, divergent information exists about the capacity of IL-17A to regulate MSCs’ osteogenic fate, depending on the tissue context and target cell type, along with contradictory findings in the same cell types. Therefore, we summarize the data showing both the pro-osteogenic and anti-osteogenic roles of IL-17, which may help in the understanding of IL-17A function in bone repair and regeneration.
Core Tip: The immune system closely interacts with the bone system in health and disease. Inflammation plays a strategic role in bone homeostasis and turnover. A proinflammatory cytokine interleukin-17 (IL-17) is produced in high amounts after bone damage and can influence mesenchymal stem cells’ fate toward early osteoprogenitor cells, either as a pro-osteogenic or an anti-osteogenic factor. Although these divergent IL-17 roles in bone formation are still not well understood, different conditions of the local microenvironment, the extent of inflammation, and the specific nature and stage of osteoprogenitor cells can influence the response to this cytokine, affecting the final cell differentiation outcome.
