Relative representation and light scatter properties of blood CD56^+low CCR5/CXCR3⁻, CD56^+int CCR5/CXCR3⁺, and CD56^+high CCR5/CXCR3⁺ NK-cell subsets.

Data were obtained using the gating and analysis strategies described in Figure 2, where representative dot plots of these three NK-cell subsets are presented.
Results are expressed as mean ± standard deviation (minimum–maximum) of the percentage of each NK-cell subset within total CD56⁺ NK-cells and as mean ± standard deviation (minimum–maximum) of the transformed side scatter (tSSC) and forward scatter (FSC) channel of each NK-cell subset.
n.s.: not statistically significant.
