Abstract: To investigate the mechanism of interleukin-21 in the immune regulation of the Chinese Yellow Feather quail body, the distribution characteristics of IL-21 were observed. The quail tonsils of 42 day old Chinese Yellow Feather quail were taken, immunohistochemical SABC method was used for histological localization of interleukin-21 in the tonsil, and the morphology and distribution of the IL-21positive cells were observed. The results showed that the IL-21 positive reaction cells were round or elliptic, and a few were fusiform, some were clumpy. The positive reaction cells were mainly distributed in the lamina propria of the underlying layer of the epithelium of cecal tonsil, and a few were around the intestinal gland. There was also a small amount of IL-21 positive cells around the germinal centers. The results confirmed that IL-21 was widely distributed in the cecal tonsil of quail. The distribution and reaction strength of IL-21 positive cells were related to the local immune cells and the immune state of the body.

Key words: interleukin-21, Chinese Yellow Feather quail, cecal tonsil, localization
