Abstract

The cationic proinflammatory cytokine Interleukin 26 (IL-26) shows antibacterial activity and inhibits the replication of cytomegalovirus and hepatitis C virus. This study evaluates the early microbicidal activities of IL-26 against major bacterial species including multi-resistant variants and . Recombinant IL-26 was bacterially expressed and studied for its microbicidal effects in culture. We show that IL-26 has strong 90% bactericidal activities against , and . Similarly, IL-26 sensitivity was also detectable in vancomycin-resistant Enterococcus species, methicillin-resistant , and carbapenem-resistant clinical isolates. Additionally, a significant, albeit weak fungicidal effect against was observed. Activities against , and were not detectable. The proinflammatory cytokine and kinocidin IL-26 shows strong bactericidal activities against and, almost selectively, against Gram-positive bacteria.

摘要

阳离子促炎细胞因子白细胞介素26(IL-26)具有抗菌活性,并能抑制巨细胞病毒和丙型肝炎病毒的复制。本研究评估了IL-26对包括多重耐药变体在内的主要细菌种类的早期杀菌活性。重组IL-26通过细菌表达,并在培养中研究其杀菌作用。我们发现IL-26对[具体细菌1]、[具体细菌2]和[具体细菌3]具有很强的90%杀菌活性。同样,在耐万古霉素肠球菌、耐甲氧西林[具体细菌4]和耐碳青霉烯[具体细菌5]临床分离株中也可检测到IL-26敏感性。此外,观察到对[具体真菌]有显著但较弱的杀真菌作用。未检测到对[具体细菌6]、[具体细菌7]和[具体细菌8]的活性。促炎细胞因子和亲嗜素IL-26对[具体细菌9]以及几乎选择性地对革兰氏阳性菌具有很强的杀菌活性。
