PURPOSE: A multicolor flow cytometry panel was designed and optimized to define the following nine mouse T cell subsets: Treg (CD3+ CD4+ CD8− FoxP3+), CD4+ T naïve (CD3+ CD4+ CD8−FoxP3− CD44int/low CD62L+), CD4+ T central memory (CD3+ CD4+ CD8− FoxP3− CD44high CD62L+), CD4+ T effector memory (CD3+ CD4+ CD8− FoxP3− CD44high CD62L−), CD4+ T EMRA (CD3+ CD4+ CD8− FoxP3− CD44int/low CD62L−), CD8+ T naïve (CD3+ CD8+ CD4− CD44int/low CD62L+), CD8+ T central memory (CD3+ CD8+ CD4− CD44high CD62L+), CD8+ T effector memory (CD3+ CD8+ CD4− CD44high CD62L−), and CD8+ T EMRA (CD3+ CD8+ CD4− CD44int/low CD62L−). In each T cell subset, a dual staining for Ki-67 expression and DNA content was employed to distinguish the following cell cycle phases: G0 (Ki67−, with 2n DNA), G1 (Ki67+, with 2n DNA), and S-G2/M (Ki67+, with 2n < DNA ≤ 4n). This panel was established for the analysis of mouse (C57BL/6J) spleen.
