Synovial Fluid Cell Proteomic Analysis Identifies Upregulation of Alpha-Taxilin Proteins in Rheumatoid Arthritis: A Potential Prognostic Marker

Figure 5

Expression of α-Taxilin in the synovium. (a) Tissue section were cut and stained with anti α-Taxilin primary antibody followed by HRP-tagged secondary antibody and subsequently developed by DAB then an image taken at 20x and 100x shows high expression of α-Taxilin protein in the synovium of RA as compared to OA and healthy control. Pink color represents the level of α-Taxilin in the synovium sample. (b) Comparative densitometric analysis of Western blot of the pool sample showing the level of circulating autoantibody against α-Taxilin in RA, OA, and healthy plasma.
