DN NK cells are present within the TINK-cell population.

<p>(A) Representative flow cytometry analysis of the expression of CD27 and CD11b on gated CD56⁺CD3⁻ TINK cells as compared with pNK cells from autologous patients and healthy control subjects. Dot plots were gated on live NK cells using a lymphocyte gate based on forward scatter versus side scatter and an NK-cell gate identifying CD56⁺CD3⁻ cells. Quadrants depicted were set on isotype controls. (B) The frequency of DN NK cells within the TINK-cell population as compared with that within the pNK-cell populations from autologous patients and healthy control subjects (n = 35; mean±SEM). (C) The frequency of CD11b⁺SP NK cells within the TINK-cell population as compared with that within the pNK-cell populations from autologous patients and healthy control subjects (n = 35; mean±SEM).
