Moreover, we found no difference in the surface expression of FcγRII/CD32 on monocytes between the SLE patients and healthy control individuals, although interpretation of this finding is limited by the inability of the anti-CD32 antibody to distinguish the activating FcγRIIa and inhibitory FcγRIIb. The gene discussed is FCGR2B; the disease is systemic lupus erythematosus.
