MDSCs are upregulated in PSGL-1-deficient mice / 中国比较医学杂志

Objective PSGL-1 is specifically expressed in leucocytes.The aim of this study was to explore the changes of myeloid-derived suppressor cells (MDSCs) in the spleen and bone marrow in PSGL-1-deficient mice.Methods PSGL-1 -/-mice were used in the experiment.After identification of the offsprings, flow cytometry was used to test the expression of CD11b and Gr-1 in C57 and PSGL-1 -/-mice.Results Compared with the C57 mice, the expression of MDSCs was up-regulated in the PSGL-1-deficient mice ( P <0.001).Conclusion The expression of MDSCs is upregulated in PSGl-1-deficient mice.
