蛔虫驱动Th2极化反应的能力已经为人所知有一段时间了。有趣的是,最近的许多研究表明,蠕虫表达的聚糖激活宿主免疫细胞是抗炎和Th2偏倚的主要原因。这篇微综述试图涵盖免疫调节聚糖在各种寄生虫中的表达生物学,它们与免疫细胞相互作用,包括细胞因子,趋化因子和抗体的产生。我们还讨论了能够结合某些聚糖的潜在细胞表面受体,以及最终导致抗炎介质产生的已知机制,以及宿主体内对Th2型的CD4+ T细胞反应的极化。最后,我们讨论了一种新的机制,通过特定的蠕虫聚糖激活抗原呈递细胞,导致2型树突状细胞成熟。
The ability of helminth parasites to drive polarized Th2 responses has been known for some time. Interestingly, many recent studies have shown that helminth‐expressed glycan activation of host immune cells accounts for much of the anti‐inflammatory and Th2‐biasing observed. This microreview attempts to cover the biology of expression of immunomodulatory glycans in various helminth parasites, the immune cells they interact with including the production of cytokines, chemokines and antibodies. We also discuss the potential   cell   surface   receptors   which   are   capable of binding certain glycans and the known mechanisms which ultimately lead to production of anti‐inflammatory   mediators   as   well   as   polarizing   CD4+ T‐cell responses to Th2‐type in the host. Lastly, we discuss a novel mechanism for activation of antigen‐presenting cells by a specific helminth glycan that leads to maturation of Type 2 dendritic cells.
