Immunofluorescence grey scale analysis results of CD3 in IEL and LPL in sheep small intestine. A-D The relative fluorescence intensities of CD3 in duodenal IEL and LPL; B-E The relative fluorescence intensities of CD3 in jejunal IEL and LPL; C-F The relative fluorescence intensities of CD3 in ileal IEL and LPL. IEL (Intestinal intraepithelial lymphocytes); LPL (lamina propria lymphocyte). P < 0.05 means significant difference
