Figure 8 Presence of interleukin 13 receptor α1‐chain (IL‐13Rα1) on enterochromaffin (EC) cells in the colon as detected by immunofluorescence technique. Colonic sections from infected C57BL/6 mice (day 14 after infection) were double immunostained for IL‐13Rα1 and 5‐hydroxytryptamine (5‐HT)/chromogranin A (CGA).(A) Representative micrograph showing expression of IL13Rα1 in colonic section. (B) Representative micrograph showing 5‐HT‐expressing cells in colonic section. (C) Representative micrograph showing 5‐HT and IL13Rα1‐expressing cells in colonic section. (D) Representative micrograph showing IL‐13 Rα1‐expressing cells in colonic section. (E) Representative micrograph showing CGA‐expressing cells in colonic section. (F) Representative micrograph showing CGA and IL13Rα1‐expressing cells in colonic section.
