Immunofluorescence grey scale analysis results of ICOS in IEL and LPL in sheep small intestine. A-D The relative fluorescence intensities of ICOS in duodenal IEL and LPL; B-E The relative fluorescence intensities of ICOS in jejunal IEL and LPL; C-F The relative fluorescence intensities of ICOS in ileal IEL and LPL. IEL (Intestinal intraepithelial lymphocytes); LPL (lamina propria lymphocyte). P < 0.05 means significant difference
