黏膜免疫系统是抵御吸入和摄入的病原微生物及病毒的第一道防线。这种防御系统在很大程度上是由分泌型IgA的作用介导的。在这项研究中,我们筛选了140株乳酸菌,以检测其对小鼠派尔集合淋巴结细胞产生IgA的诱导作用。我们挑选出一株并将其命名为植物乳杆菌AYA。我们发现植物乳杆菌AYA可诱导派尔集合淋巴结树突状细胞产生白细胞介素 - 6(IL - 6),这种产生作用促进IgA⁺ B细胞分化为分泌IgA的浆细胞。我们还观察到,给小鼠口服植物乳杆菌AYA会使小肠和肺部的IgA产生增加。这种IgA的产生与保护能力密切相关,在致命流感病毒感染后,接受处理的小鼠比对照小鼠存活时间更长。因此,我们的数据揭示了植物乳杆菌AYA菌株具有一种新的免疫调节作用,它能增强黏膜IgA的产生,并提供对呼吸道流感病毒感染的保护。
The mucosal immune system provides the first line of defense against inhaled and ingested pathogenic microbacteria and viruses. This defense system, to a large extent, is mediated by the actions of secretory IgA. In this study, we screened 140 strains of lactic acid bacteria for induction of IgA production by murine Peyer’s patch cells. We selected one strain and named it Lactobacillus plantarum AYA. We found that L. plantarum AYA-induced production of IL-6 in Peyer’s patch dendritic cells, with this production promoting IgA+ B cells to differentiate into IgA-secreting plasma cells. We also observed that oral administration of L. plantarum AYA in mice caused an increase in IgA production in the small intestine and lung. This production of IgA correlated strongly with protective ability, with the treated mice surviving longer than the control mice after lethal influenza virus infection. Our data therefore reveals a novel immunoregulatory role of the L. plantarum AYA strain which enhances mucosal IgA production and provides protection against respiratory influenza virus infection.
