Abstract

Soup is an important presence in diet, but its absorption and transport mechanism by the human body remains unclear. In this study, Caco-2 intact cell and monolayer cell models were constructed to simulate small intestine absorption on colloidal nanoparticles (CNPs) isolated from lamb soup. The intracellular localization of CNPs was viewed by laser confocal microscopy (LSCM). CNPs uptake and release pathways were explored by differences in CNPs concentrations in 5 endocytosis inhibitor models and 4 exocytosis inhibitor models. Results indicated that CNPs endocytosis by Caco-2 cells was restrained by Nystatin and Cytochalasin D, with exocytosis being inhibited by Nocodazole and Monensin. Therefore, the major absorption pathways for CNPs were caveolin-dependent endocytosis, macropinocytosis and phagocytosis. The major transport pathways were microtubule-vesicle-mediated protein transport to the membrane and transportation between the Golgi apparatus and membrane. This study may provide theoretical support for the transport mechanism of soup products in the small intestine.
