Increased presence of IL-17A
T cells in the ileum of F4
ETEC infected piglets. Cryosections were stained with anti-IL-17A (FITC, green) and anti-CD3 mAbs (Texas Red-X, red). The nuclei were counterstained with Hoechst (blue). Images are representative for all piglets in both groups. The arrows indicate colocalization of CD3 and IL-17A.
