Phenotypical differences. (A) P2X7R, P2Y11R, and Ado2aR relative gene expression by tonsillar CD39⁻CD73⁻ (DN) ILC3, CD39⁺CD73⁺ (ecto⁺) ILC3, CD4⁺CD39⁻ T cells, and CD4⁺CD39⁺ T cells. Data are normalized to the expression of GAPDH. Data are presented as mean ± SEM. *P < .05. Data are summarized from or representative of 3 to 4 independent experiments. (B) Representative flow cytometric analysis of CD25, CD45RO, CD45RA, NKp44, CD103, and CD69 on ecto⁺ ILC3 (blue line) and DN ILC3 (green line). Horizontal line represents isotype control. Quantification is shown in the lower panel. Data are representative of as individual values of 3 to 4 independent experiments; *P < .05 by Student t test.
