Abstract

IL-10 and IL-6 play important roles in protecting against inflammation and clearing pathogens from the body. In this study, homologous compounds of IL-10 and IL-6 were identified in channel catfish, and their immune responses were analyzed. The CDS sequences of IL-10 and IL-6 were 549 bp and 642 bp, respectively, and showed the highest homology with . In addition, the expression of the IL-10 and IL-6 genes was ubiquitous in 10 tissues examined. IL-10 is highly expressed in the liver and slightly expressed in the gill. The high expression of the IL-6 gene was observed in the spleen, heart, and gonad, with the lowest levels in the liver. LPS, Poly(I:C), PHA, and PMA showed a highly significant increase in IL-10 and IL-6 expression 48 h after CCK stimulation ( < 0.01). Otherwise, Yersinia ruckeri, Streptococcus iniae, channel catfish virus, and deltamethrin induced IL-10 and IL-6 expression, varying in intensity between different organs. Our results suggest that IL-10 and IL-6 are involved in the immune response of the host against the pathogen.

摘要

白细胞介素-10(IL-10)和白细胞介素-6(IL-6)在抵御炎症和清除体内病原体方面发挥着重要作用。在本研究中,在斑点叉尾鮰中鉴定出了IL-10和IL-6的同源化合物,并分析了它们的免疫反应。IL-10和IL-6的编码序列(CDS)分别为549 bp和642 bp,与……显示出最高的同源性。此外,IL-10和IL-6基因在检测的10个组织中均普遍表达。IL-10在肝脏中高表达,在鳃中低表达。IL-6基因在脾脏、心脏和性腺中高表达,在肝脏中表达水平最低。脂多糖(LPS)、聚肌苷酸胞苷酸(Poly(I:C))、植物血凝素(PHA)和佛波酯(PMA)在CCK刺激后48小时显示IL-10和IL-6表达显著增加(<0.01)。此外,鲁氏耶尔森菌、海豚链球菌、斑点叉尾鮰病毒和溴氰菊酯诱导IL-10和IL-6表达,不同器官之间诱导强度有所不同。我们的结果表明,IL-10和IL-6参与宿主针对病原体的免疫反应。
