Analysis of leukocytes cell subpopulation in spleen

Analysis of spleen leukocyte subpopulations by FACS. Splenocytes were collected from WT and B-Fcgr1/Fcgrs KO mice (n=3, 7-week-old). Flow cytometry analysis of the splenocytes was performed to assess leukocyte subpopulations. A. Representative FACS plots. Single live cells were gated for the CD45+ population and used for further analysis as indicated here. B. Results of FACS analysis. Percent of T cells, B cells,NK cells, dendritic cells, granulocytes, monocytes and macrophages in B-Fcgr1/Fcgrs KO mice were similar to those in the C57BL/6 mice, demonstrating that deleting of Fcgr1/Fcgrs does not change the overall development, differentiation or distribution of these cell subtypes in blood. Values are expressed as mean ± SEM.

Analysis of T cell subpopulation in spleen

Analysis of spleen T cell subpopulations by FACS. Splenocytes were isolated from female C57BL/6 and B-Fcgr1/Fcgrs KO mice (n=3, 7-week-old). Flow cytometry analysis of the splenocytes was performed to assess leukocyte subpopulations. A. Representative FACS plots. Single live CD45+ cells were gated for CD3+ T cell population and used for further analysis as indicated here. B. Results of FACS analysis. The percent of CD8+ T cells, CD4+ T cells, and Tregs in B-Fcgr1/Fcgrs KO mice were similar to those in the C57BL/6 mice. Values are expressed as mean ± SEM.

Summary

Protein expression analysis:

Mouse Fcgr1 and Fcgrs were detectable in B cells, DCs, NK cells, monocytes and neutrophils of wild-type mice. Mouse Fcgr1 and Fcgrs were not detectable in B cells, DCs, NK cells, monocytes or neutrophils of B-Fcgr1/Fcgrs KO mice.

Leukocytes profile:

Percentages of T, B, NK cells, monocyte/macrophages, and DC were similar in B-Fcgr1/Fcgrs KO mice and wild-type mice, demonstrating that deleting of Fcgr1/Fcgrs does not change the overall development, differentiation, or distribution of these cell types in spleen, lymph node leukocytes and blood.
