Analysis of immune cells and their subsets in peripheral blood and spleen of CAST/EiJ mice
Objective To explore the possible causes of CAST/EiJ mouse susceptibility to multiple pathogens,the immune cell phenotypes in the peripheral blood and spleen of CAST/EiJ mice were analyzed to clarify their composition.Methods Classical dendritic cells(cDCs),natural killer(NK)cells,B lymphocytes,T lymphocytes,and their subsets in the peripheral blood and spleen of CAST/EiJ mice and C57BL/6J mice were detected by flow cytometry using the cell surface markers CD3,CD4,CD8,CD11b,CD11c,CD19,CD27,CD49b,and TCRβ.Results There was no significant difference in the proportion of cDCs between CAST/EiJ and C57BL/6J mice,but the cDC1 cell subset population was smaller in CAST/EiJ.The proportions of NK cells(mainly mature NK cell subsets)and T lymphocytes(mainly CD8+T cells)were both lower in CAST/EiJ mice than C57BL/6J mice,while the proportion of B cells was higher in CAST/EiJ mice than C57BL/6J mice.Conclusions The proportions of NK and T lymphocytes in CAST/EiJ mice were lower than those in C57BL/6J mice.
