      Description
      • This gene encodes a receptor for the Fc portion of immunoglobulin G, and it is involved in the removal of antigen-antibody complexes from the circulation, as well as other responses, including antibody dependent cellular mediated cytotoxicity and antibody dependent enhancement of virus infections. The receptor encoded by this gene is expressed on natural killer (NK) cells as an integral membrane glycoprotein anchored through a transmembrane peptide. Natural cytotoxicity receptors 1(NCR1) mediate lysis of a variety of tumor and virus-infected cells by natural killer (NK) cells. Upon engagement, NCR trigger the cytolytic activity and cytokine release of NK cells through association with ITAM-containing signaling molecules. NCR1 has been implicated in NK cell-mediated lysis of several autologous tumor and pathogen-infected cell lines.
      • The regulatory region and exons 1~5 of mouse Fcgr4 gene that encode the full-length protein were replaced by human FCGR3A(F158V) exons 1~6 and regulatory region in B-hCD16A /hNKP46 mice(CB-17 SCID) mice. The exons 1~7 of mouse NKp46 gene that encode the extracellular domain were replaced by human NKP46 exons 1~7 in B-hCD16A/hNKP46 mice(CB-17 SCID).
      • Mouse NKP46 was only detectable in wild-type CB-17 SCID mice. Human NKP46 was exclusively detectable in homozygous B-hCD16A/hNKP46 mice(CB-17 SCID), but not in wild-type CB-17 SCID mice. Mouse CD16A was detectable in wild-type CB-17 SCID mice. Human CD16A was exclusively detectable in homozygous B-hCD16A/hNKP46 mice(CB-17 SCID), but not in wild-type CB-17 SCID mice.
      • B-hCD16A/hNKP46 mice(CB-17 SCID) provide a powerful preclinical model for in vivo evaluation of anti-CD16A and NKP46 antibodies.
      • Application: For example, this product is used for pharmacodynamics and safety evaluation of anti-CD16A and NKP46 antibodies for cancers.

      Frequency of leukocyte subpopulations in spleen, blood and bone marrow

      Frequency of leukocyte subpopulations in spleen by flow cytometry. Splenocytes (A), blood (B) and bone marrow (C) were isolated from wild-type CB-17 SCID mice and homozygous B-hCD16A/hNKP46 mice(CB-17 SCID) (n=3, 7-week-old). Flow cytometry analysis was performed to assess the frequency of leukocyte subpopulations. Percentages of NK cells, DCs, monocytes, macrophages and neutrophils in B-hCD16A/hNKP46 mice(CB-17 SCID) were similar to those in CB-17 SCID mice, demonstrating that humanization of CD16A and NKP46 does not change the frequency or distribution of these cell types in spleen, blood and bone marrow. Values are expressed as mean ± SEM. Significance was determined by two-way ANOVA test. *P < 0.05, **P < 0.01, ***P < 0.001.
