Moreover, based on the data from GPL6947, GPL570, GPL20171, and GPL13158 platforms, the expression of genes encoding CD47, TSP-1, SIRP-α, and integrin subunits α4 and αL was significantly higher in the peripheral blood samples of RA patients than in healthy people (RA=1238, healthy=120) (Figures 1K–O). This evidence concerns the gene SIRPA and rheumatoid arthritis.
