As a final means of assessing FcR interactions, we utilized a panel of BW5147 mouse T-cell lymphoma cells stably transfected to express a chimeric receptor containing a rhesus macaque FcγR (FcγRI, FcγRIIa, FγRIIb, or FcγRIII) ectodomain fused to the CD3ζ intracellular signaling domain (50). The gene discussed is FCGR2A; the disease is T-cell non-Hodgkin lymphoma.
