| Figure 4: Expression of the chemokine receptors CXCR3 and CXCR4 for NK (top histogram) and NKT (bottom histogram) cells. PBMCs were incubated for 30 minutes in the presence of AFAe. Untreated (UT) cultures served as a control. Flow cytometric analysis included electronic gating on CD3-CD56+ NK cells and CD3-CD56+ NKT cells. |
