30‐Parameter Flow Cytometry Panel to Characterize iNKT, NK, Unconventional and Conventional T Cells

Thomas Liechti, Mario Roederer Cytometry PART A, Volume 95, Issue 9, 946-951 (2019)

PURPOSE: This panel enables the in‐depth immunophenotyping of unconventional CD3+ T‐cell populations such as invariant natural killer T cells (iNKT; CD1d:PBS57 tetramer), γδ T cell subsets (TCR Vδ1, TCR Vδ2, TCR Vγ9), and mucosal‐associated invariant T cells (MAIT; CD161, TCR Vα7.2) in combination with conventional CD3+ T cells (CD4, CD8) and natural killer (NK) cell subsets (CD16, CD56) (Table 1). We included markers to assess differentiation stages (CCR7, CD27, CD28, CD45RA, CD57, and CD95) and expression of cytokine receptors (CD122, CD127), activation markers (CD38, HLA‐DR), chemokine receptors (CCR5, CXCR5), the co‐inhibitory molecule PD‐1, and activating and inhibitory NK receptors (CD158, CD244, and CD318). This unique combination of markers enables a thorough phenotypic characterization of these cell subsets (Table 2).
