Selective granulocyte and monocyte apheresis in inflammatory bowel disease: Its past, present and future

Figure 2 A schematic diagram of the selective adhesion of myeloid granulocyte and monocyte to cellulose acetate carriers. Cellulose acetate beads inside the Adacolumn are capable of selectively adsorbing circulating neutrophils and monocytes by binding to IgG fragments (Fcγ) and immune complements complexes. Lymphocytes are not absorbed as they rarely express complement receptor. Modified from reference[31].
