Representative photomicrographs of the TNF-α immuno-stained splenic tissue sections for the effect of dietary supplementation of CUR, IMI, and their combinations in spleen of Ross 308 broiler chickens. (A,B): control and CUR groups for TNF-α showing weak expression in splenic tissue. (C): showing up-regulation of the TNF-α expression in the IMI-treated group in splenic tissue. (D,E): CUR-supplemented groups, showed down-regulation of TNF-α expression in the CUR co-treated group or CUR pro/and co-treated groups. (Scale bar is 25 μm).
