From: High synovial expression of the inhibitory FcγRIIb in rheumatoid arthritis
Co-localisation of CD163 with Fc gamma receptor (FcγR)I, II, IIb and III. (a-d) Rheumatoid arthritis synovial tissue showed overlapping expression of the macrophage marker CD163 with the expression of FcγRI (a), FcγRII (b), FcγRIIb (c) and FcγRIII (d). The majority of the CD163 positive macrophages expressed FcγRIIb. However, note that a CD163 positive cell lacked FcγRIIb expression. (Original magnification ×400.)
