Molecular characterization and expression analysis of interleukin 15 (IL15) and interleukin-15 receptor subunit alpha (IL15Rα) in dojo loach (Misgurnus anguillicaudatus): Their salient roles during bacterial, parasitic and fungal infection

Publication date: November 2018Source: Molecular Immunology, Volume 103Author(s): Xiaoyao Chen, Weiguang Kong, Yongyao Yu, Shuai Dong, Zhenyu Huang, Wei Yu, Jie Xu, Yanzhi Luo, Qingchao Wang, Zhen XuAbstractInterleukin 15 (IL15) is a pleiotropic cytokine that participates in innate and adaptive immunity along with its receptor α-chain (IL15Rα). In order to investigate the potential roles of IL15 and IL15Rα in dojo loach (Misgurnus anguillicaudatus), we firstly cloned the cDNA sequence of Ma-IL15 and Ma-IL15Rα, which contain 1096bp and 1236bp and code proteins of 193 amino acids and 210 amino acids, respectively. A short signal peptide and Pfam IL15 domain were found in Ma-IL15, while a highly conserved sushi domain existed in Ma-IL15Rα. Ontogeny analysis indicated that significantly i...
