摘要： Taenia asiatica is a zoonotic parasite found in the human intestine and pig liver that evolved various strategies to survive the host's defenses. Exosomes are membranous vesicles released by cells and are an important vehicle in parasite-host interactions. However, no literature exists on the specific infection mechanisms of T. asiatica against the host defense response, and further research is required to understand the parasite-host interaction. In this study, we investigated the host's differentially expressed genes (DEGs) while stimulating them with exosomes derived from the T. asiatica adult worm (Tas-exo) on LoVo by RNA-seq analysis. Our results identified 348 genes as being significantly differentially expressed for the Tas-exo group when comparing with that of the NC group. Some of these genes are related to modulation of cell proliferation and cell autophagy. Surprisingly, autophagy and cell proliferation have crucial roles in the defense against parasites; accordingly, we detected cell proliferation and autophagy in LoVo cells by CCK8, immunofluorescence, and Western blotting, demonstrating that Tas-exo could inhibit LoVo cell proliferation and autophagy via AMPK pathway. When P62 and p-mTOR/mTOR expression were significantly increased, BeclinI and pAMPK/AMPK were significantly decreased. These results expand our understanding of parasite-host interactions mediated by exosomes.
