IL-2 induction of NKp44 expression on CD56^bright NK cells is inhibited by mycobacteria.

<p>A) FACS plot analysis of NKp44 expression from NK cells cultured in the presence or the absence of IL-2 (100U/ml) and or <i>M. bovis</i> BCG (MOI 1:5) for 5 days. B) Bar graphs showing B) significant increase of CD56 MFI of the NKp44⁺ NK cell population and C) significant decreased frequencies of IL-2 induced NKp44⁺ NK cell in the presence of mycobacteria from three independent experiments and donors (Paired t test, *p<0.05, **p<0.01).
