The trans‐well system was performed as in Fig
1. The control wells contained only unused schistosomal medium; supernatant wells contained 0.1 μm of the filtered schistosomal‐growing medium; Th wells contained sorted CD4
+CD11c
− from spleens; Th+APCs contained sorted CD4
+CD11c
− and CD4
−CD11c
+ in 5:1 ratio, respectively.
