Proteomic Profiling of an Exosome-Enriched Extracellular Vesicle Fraction and Structural Characterization of SMPDL3A in the Carcinogenic Liver Fluke Clonorchis sinensis.

ABSTRACT: Exosomes are important mediators of host-parasite communication and contain diverse molecules that may support the survival of Clonorchis sinensis in the biliary tract. To explore their biochemical properties, exosomes isolated from excretory-secretory products of Korean C. sinensis isolates were characterized through integrated morphological, proteomic, and gene ontology analyses. The vesicles exhibited typical exosomal size ranges and marker profiles, and their protein components were enriched for cytoskeletal, metabolic, and vesicle-trafficking components relevant to epithelial signaling and immune modulation. Among these proteins, sphingomyelin phosphodiesterase acid-like 3A (SMPDL3A) was examined in detail to obtain molecular evidence suggesting its role in sphingolipid
