树突状细胞(DC)在与各种不同微生物刺激物接触后,可被激活并逐渐成熟。根据不同的成熟信号,DC可激发Th细胞分化为Th1、Th2或调节性T细胞。引起Th2极化反应的蠕虫产物是与宿主有长期接触的虫体成分。对于这些蠕虫感染初期和早期能否激活抗原呈递细胞(APCs),并极化Th2型免疫反应 Dendritic cells (DCs) can be activated and gradually mature upon contact with a variety of different microbial stimuli. Depending on the mature signal, DCs can stimulate Th cells to differentiate into Th1, Th2 or regulatory T cells. The helminth product that causes the Th2 polarization reaction is a parasitic component that has long-term contact with the host. Whether antigen-presenting cells (APCs) can be activated in the early and early stages of these worm infections and polarized Th2-type immune responses
