For ow cytometry, fresh blood was collected in anticoagulant tubes (BD, 8215736) and peripheral blood mononuclear cells (PBMC) were obtained by
lymphocyte isolate medium (KeyGEN BioTECH, kga831). Cells were washed and treated with the
Fixation/Permeabilization Solution (BD) for Ki67 detection, incubated with
ow cytometry antibodies (BD Pharmingen), and resuspended in phosphate-buffered saline (PBS) with 1% bovine serum albumin (BSA). Then cells were determined with
BD FACS Calibur Flow Cytometer. Antibody collocations were as follows: CD4 + CD25 + T cells:
FITC Anti-Mouse CD4 (eBioscience, clone: RM4-4),
APC Anti-Mouse CD25 (eBioscience, clone: PC61.5); CD4 + CD44 + T cells:
FITC Anti-Mouse CD4 (eBioscience, clone: RM4-4),
PerCP Anti-Mouse CD44 (BioLegend, clone: IM7); CD4 + CD62L + T cells:
FITC Anti-Mouse CD4 (eBioscience, clone: RM4-4);
PE Anti-Mouse CD62L (BD, clone: MEL-14); CD4 + Ki67 + T cells:
PE Anti-Mouse CD4 (BD, clone: RM4-5);
FITC Anti-Mouse Ki67 (BioLegend, clone: 16A8).
