      Background InformationTransmembrane receptor CD16-2 (UniProt: Q8R477; also known as CD16-2, Fcgr4, FcgRIV, Fc gammaRIV, FcgammaRIV, Fcgr3a, CD16-2, Transmembrane receptor CD16-2) is encoded by the Fcgr4 (also known as Fcgr3a, Fcrl3) gene (Gene ID: 245256) in murine species. Murine species express three classes of activating IgG Fc receptors, the high affinity receptor FcgRI, the low affinity receptor FcgRIII, and the FcgRIV or CD16-2. CD16-2, a novel mouse receptor that displays significant homology to CD16/FcgRIII. It is a receptor for soluble IgG2a and 2b complexes, but not necessarily for cellular bound IgG2a. CD16-2 is expressed in peripheral blood leukocytes and in spleen, thymus, colon, and intestine. Similar to other activating receptors, CD16-2 possesses a charged residue within its transmembrane domain that is necessary for association with an ITAM (immunoreceptor tyrosine-based activation motif) bearing accessory protein. Both CD16-2 (FcgRIV) and FcgRIII are considered to be essential for mediating type II and type III autoimmune responses via FcRc-LAT-dependent generation of C5a. However, FcgRIII-deficient mice display compensatory enhanced CD16-2 expression that offers protection from lung inflammation and exhibit reduced sensitivity to IgG2a/b-mediated hemolytic anemia.

      Key Applications
      • Flow Cytometry
      • Neutralizing
      Application NotesFlow Cytometry Analysis: 20 µg/mL from a representative lot, when added prior to APC-conjugated 9E9, blocked the staining of FcgRIV-positive granulocytes and monocytes by APC-conjugated 9E9 (Courtesy of Jeanette Leusen, Ph.D, University Medical Center, Utrecht, Netherlands).

      Flow Cytometry Analysis: A representative lot detected FcgRIV-positive granulocytes and monocytes from wild-type, but not Fcgr4-knockout mice (Nimmerjahn, F., et al. (2010). Proc. Natl. Acad. Sci. U. S. A. 107(45):19396-19401).

      Flow Cytometry Analysis: A representative lot, pre-conjugated with Alexa Fluor® 647, immunostained murine macrophages, neutrophils, dendritic cells, but not FcgRIII-expressing NK cells. Clone 9E9 also stained a FcgRIV-negative, B220-positive peripheral blood cell population (Syed, S.N., et al. (2009). Eur. J. Immunol. 39(12):3343-3356).

      Neutralizing Analysis: A representative lot, when administered (400-500 µg) via i.v. injection prior to anti-RBC 34-3C-IgG2b (50 µg) i.p. injection, prevented anemia (RBC depletion) induction by 34-3C-IgG2b. Clone 9E9 also prevented immunocomplex (IC) challenge-induced alveolar RBC & PMN infiltration in IC-sensitized mice (Syed, S.N., et al. (2009). Eur. J. Immunol. 39(12):3343-3356).

      Neutralizing Analysis: A representative lot suppressed both wild-type and Fcgr1-/Fcgr3-knockout mouse peritoneal macrophages-mediated phogocytosis of red blood cells (RBCs) opsonized with anti-RBC IgG2b, but not anti-RBC IgG2a (Syed, S.N., et al. (2009). Eur. J. Immunol. 39(12):3343-3356).

      Neutralizing Analysis: A representative lot prevented immune complex binding-induced activation of Fcgr3-deficient mouse neutrophils (Jakus, Z., et al. (2008). J. Immunol. 180(1):618-629).

      Neutralizing Analysis: A representative lot, when administered (200 µg) via i.v. injection 30 min prior to anti-platelet 6A6-IgG2a Fc fusion (3.5 µg) injection, reduced the extend of thrombocytopenia (platelet depletion) induction by 6A6-IgG2a (Nimmerjahn, F., et al. (2005). Immunity. 23(1):41-51).
