[Method] The differentially expressed cDNA fragment was obtained by DD-RTPCR (differential display RT-PCR). The cDNA library of peripheral blood leukocytes which were separated from common carp and stimulated by mitogen was screened with a probe labeled with DIG (digoxigenin). The IL-10 full-length cDNA was cloned from 0.8×104 pfu of recombinant phages, and the sequence analysis and homology comparison were carried out. [Result] Sequence analysis indicated that the IL-10 full-length cDNA of common carp was 1 117 bp long, containing a 55 bp 5’-UTR, a 522 bp 3’-UTR, and a 540 bp open reading frame(ORF) encoding 179 amino acids. In addition, there were three mRNA instability motifs (ATTTA) in the 3’-untranslated region. The deduced protein sequence shared typical sequence features of the IL-10 family. Homology comparison indicated that the obtained sequence shared 89.1% homology with the carp IL-10 gene from GenBank. [Conclusion] This study laid foundation for further study of the expression manner, functional characteristic and regulation mechanism of IL-10 in vivo and the interaction mechanism in the inflammatory reaction and immune response.展开更多

文摘Several experimental evidence suggests a link between brain Herpes simplex virus type-1 infection and the occurrence of Alzheimer’s disease.However,the molecular mechanisms underlying this association are not completely understood.Among the molecular mediators of synaptic and cognitive dysfunction occurring after Herpes simplex virus type-1 infection and reactivation in the brain neuroinflammatory cytokines seem to occupy a central role.Here,we specifically reviewed literature reports dealing with the impact of neuroinflammation on synaptic dysfunction observed after recurrent Herpes simplex virus type-1 reactivation in the brain,highlighting the role of interleukins and,in particular,interleukin 1βas a possible target against Herpes simplex virus type-1-induced neuronal dysfunctions.
文摘目的探究血清瓜氨酸组蛋白H3(citrullinated histone H3,CitH3)、降钙素原(procalcitonin,PCT)及白细胞介素-10(interleukin-10,IL-10)对体外心肺复苏(extracorporeal cardiopulmonary resuscitation,ECPR)后急性肺损伤(acute lung injury,ALI)的预测价值。方法择取2021年1月至2024年4月行ECPR的患者126例,入院次日空腹采血测定患者血清CitH3、PCT、IL⁃10水平。根据ECPR后ALI发生与否分为ALI组与非ALI组,对比两组临床资料及血清CitH3、PCT、IL-10水平,Logistic多因素回归分析ECPR后ALI发生的危险因素。另外受试者工作特征(receive operating characteristic,ROC)曲线分析血清CitH3、PCT、IL-10对ALI的预测价值。结果因6例患者未配合完成相关检查等被剔除,最终纳入120例患者,其中住院期间ALI发生28例(ALI组),ALI未发生92例(非ALI组)。ALI组入院时急性生理学和慢性健康状况评分(Acute Physiology and Chronic Health Scoring System,APACHEⅡ)、序贯器官衰竭评估(Sequential Organ Failure Assessment,SOFA)、心肺复苏到自主循环恢复时间均大于非ALI组(P<0.05);ALI组血清CitH3、PCT、IL-10水平均高于非ALI组(P<0.05)。Logistic多因素回归分析显示心肺复苏到自主循环恢复时间、血清CitH3、PCT及IL-10是ALI发生的独立危险因素(P<0.05)。ROC曲线显示,血清CitH3、PCT、IL-10单一及3项联合预测ALI发生的曲线下面积(area under curve,AUC)分别为0.886、0.837、0.852、0.951,3项联合的AUC均大于PCT、IL-10单一检测(P<0.05)。结论ECPR后ALI发生患者血清CitH3、PCT、IL-10水平上升,对ALI发生有一定的预测价值,特别是联合检测效能更显著。
