Clonorchis sinensis adult-derived proteins elicit Th2 immune responses by regulating dendritic cells via mannose receptor.

Collectively, we validated that CsTPs could suppress the maturation of BMDCs in the presence of LPS via binding MR, and showed that the CsTPs-pulsed BMDCs actively polarized naive T helper cells to Th2 cells though the production of IL-10 instead of IL-12. CsTPs endowed host with the capacity to facilitate Th2 cytokines production including IL-13 and IL-4 in vitro and vivo. The study might provide useful information for developing potential therapeutic targets against the disease.
