Thrombospondin-1 (TSP1/THBS1) plays a major role in the pathophysiology of rheumatoid arthritis (RA); however, its interface with the cytokine network involved in RA has not been delineated. Correlations were performed between plasma levels of TSP1 and selected cytokines from blood samples collected from 20 patients affected by RA and 13 healthy donors (control). Plasma levels of TSP1 and tissue growth factor beta (TGFβ) were determined by standard enzyme-linked immunosorbent assay, and cytokines were measured by protein profiling rolling-circle amplification (RCA). TSP1 circulating levels in plasma were found significantly increased in the RA patients when compared with control individuals (P = 0.039). The plasma levels of TGFβ were also increased in the RA patients, which indicates a statistical trend. Cytokine levels of interleukin (IL)-4, IL-5, IL-12, chemokine CXC 10 (CXCL10/IP10), and chemokine CC 4 (CCL4)/MIP1β were significantly increased in the RA patients when compared with the control group. In summary, this study demonstrates increased plasma levels of TSP1, which correlated with increased levels of proinflammatory cytokines in plasma of RA patients. More detailed research is required to explore the cytokine imprint yielded by this study and its interface with TSP1 and TGFβ.
