Rheumatoid arthritis is a complex systemic disease that ultimately leads to the progressive destruction of articular and periarticular structures. Novel data indicate that the innate immune system (through activation of Toll-like receptors) is involved in articular pathophysiology, including the recruitment of inflammatory cells, and that periarticular factors such as adipocytokines contribute to the perpetuation of joint inflammation. The deleterious process of joint destruction is mediated by intracellular signaling pathways involving transcription factors, such as nuclear factor kappa B, cytokines, chemokines, growth factors, cellular ligands, and adhesion molecules. Advances in molecular biology techniques have identified T-cell-independent and B-cell-independent pathways that operate at different stages of the disease. Cytokine-independent pathways appear to be responsible for maintaining basic disease activity that is not affected by currently available therapies. Using this knowledge in combination with gene-transfer and gene-silencing approaches, bench-to-bedside strategies will be developed, thus enabling the creation of novel treatments for rheumatoid arthritis.
