Abstract

Herpes simplex virus type 2 (HSV-2) is responsible of the continuously increasing viral infections in humans. In a previous study we demonstrated that the exopolysaccharide produced by Bacillus licheniformis strain B3-15 (EPS-B3-15), was able to hinder the HSV-2 replication in peripheral blood mononuclear cells (PBMC) and this antiviral activity appear to be related to a significant stimulation of the Th1-cytokines. In this study we analyse the role of EPS-B3-15 on Th2 cytokine production by PBMC infected or not with HSV-2. EPS-B3-15 demonstrate the ability to induce a particular cytokine network with consequent effects on the immune cells during HSV-2 infection.

浅海喷口源细菌胞外多糖拮抗疱疹病毒免疫功能紊乱的作用
单纯疱疹病毒2型(HSV-2)是人类病毒感染不断增加的原因。在之前的研究中,我们证明了地衣芽孢杆菌B3-15菌株(EPS-B3-15)产生的胞外多糖能够抑制HSV-2在外周血单核细胞(PBMC)中的复制,这种抗病毒活性似乎与th1细胞因子的显著刺激有关。在本研究中,我们分析了EPS-B3-15对感染或未感染HSV-2的PBMC产生Th2细胞因子的作用。EPS-B3-15显示出在HSV-2感染期间诱导特定细胞因子网络并对免疫细胞产生后续影响的能力。
