摘要:
This article reviews the roles of host-microbe interactions in intestinal disorders and tumors from the perspective of host cell-microbial cell crosstalk.As a crucial environmental factor in the gut,gut microbiota significantly influences host intestinal pathologies and tumors,and this interaction is bidirectional.Gut microbes can directly adhere to and contact epithelial cells,activating intracellular signaling pathways and affecting the development of inflammation and cancer.Simultaneously,gut microbes can produce various proteins,secondary metabolites or exosomes;these bacterial-derived products can regulate intestinal epithelial cells,immune,and neuronal cells in a contact-independent manner,thereby influencing disease progression.Recent research has increasingly focused on the regulatory factors shaping the gut microbiota.Notably,the host has been identified as a key factor influencing gut microbiota.For instance,specific adhesion proteins on the surface of host intestinal cells,intestinal immunity,and even the host’s blood type can impact the composition and function of the gut microbiota.These altered microbial communities can,in turn,further affect the host’s intestine,influencing the progression of intestinal diseases and tumors.Therefore,elucidating the bidirectional interplay between the host and microbiota is essential for a deeper understanding of disease pathogenesis and will provide a theoretical foundation and guidance for the precise modulation of gut microbiota in the future.
