Figure 5. The in situ localization and distribution of IL-17A and IL-17F in the CD4⁺ T cells treated with Jagged-1.

The isolated CD4⁺ T cells were treated with Jagged-1 for 72 h. The cells were fixed, permeablized and stained with monoclonal antibodies specific for IL-17A (green) and IL-17F (red). The nuclei were stained with DAPI (blue). All the cells were observed at magnification ×200. Three independent experiments were repeated. *p < 0.05, vs. the corresponding control.
