Distribution of interleukin 17 receptor mRNA in rhesus macaques / 中国免疫学杂志

ABSTRACT

Objective:To delineate the distribution and abundance of interleukin 17 receptor mRNA in normal tissues of rhesus macaques.Methods:Tissue samples were collected from different systems including lymphoid system,digestive system and genital system and the mRNA levels of IL-17RA and IL-17RC were examined by real time RT-PCR.Meanwhile the levels of IL-17RA and IL-17RC mRNA in the PBMCs of rhesus macaques,African green monkeys and cynomolgus monkeys were examined.Results:IL-17RA mRNA was expressed in all the tested tissues and the levels were significantly different among these systems (P＜0.05).IL-17RC mRNA level in the large intestine was higher than that in the small intestine.IL-17RA mRNA level in rhesus macaque PBMCs was 3 and 5 times higher than that of cynomolgus monkeys and African green monkeys respectively,while IL-17RC mRNA in the PBMCs was below the limit of detection.Conclusion:IL-17RA is widely distributed in rhesus macaques;the expression level is different among different tissues and species.
