摘要：

Introducing specific strains of probiotics into the gut microbiome is a promising way to modulate the intestinal microbiome to treat various health conditions clinically. However, oral probiotics typically have a temporary or limited impact on the gut microbiome and overall health benefits. Here, we reported a 3D printed cellulose-derived spiral tube-like scaffold that enabled high efficacy of the oral delivery of probiotics. Benefiting from the unique surface pattern, this system can effectively extend the retention time of loaded probiotics in the gut without invading nearby tissues, provide a favorable environment for the survival and long-term colonization of loaded probiotics, and influence the intestinal ecosystem as a dietary fiber after degradation. We demonstrate Roseburia intestinalis-loaded scaffold exerts noticeable impacts on the regulation of the gut microbiome to treat various gut-related diseases, including obesity and inflammatory bowel disease; thus, we provide a universal platform for oral delivery of probiotics.
