Abstract
- Rheumatoid arthritis (RA) is a systemic autoimmune disease characterized by joint inflammation and joint pain. Much of RA treatment is focused on suppressing inflammation, with the idea being that if inflammation is controlled other symptoms, such as pain, will disappear. However, pain is the most common complaint of RA patients, is often still present following the resolution of inflammation, and can develop prior to the onset of inflammation. Thus, further research is needed to better understand RA-associated pain mechanisms. A number of preclinical rodent models commonly used in rheumatology research have been developed based on bedside-to-bench and reverse translational approaches. These models include collagen-induced arthritis, antigen-induced arthritis, streptococcal cell wall-induced arthritis, collagen antibody-induced arthritis, serum transfer from K/BxN transgenic mice and tumor necrosis factor (TNF)-transgene mice. They have led to increased understanding of RA pathogenesis and have aided the development of successful RA treatments. More recently, these models have been used to elucidate the complexities of RA associated pain. Several potentially modifiable mechanisms, other than inflammation, have been investigated in these models and may in turn lead to more effective treatments. Furthermore, preclinical research can indicate when specific treatment strategies may benefit specific patient subgroups or at which disease stage they are best used. This review not only highlights RA-associated pain mechanisms, but also suggests the usefulness of preclinical animal research based on a bedside-to-bench approach.<br />Comment: 33 pages, 3 figures
