Plant-Derived Alkaloids: The Promising Disease-Modifying Agents for Inflammatory Bowel Disease
Conclusion This paper summarizes the current findings regarding the anti-colitis activity of plant-derived alkaloids and shows how these alkaloids exhibit significant and beneficial effects in alleviating colonic inflammation. These natural alkaloids are not only promising agents for IBD treatment but are also components for developing new wonder drugs. However, the underlying molecular mechanisms or toxicological evaluation of most plant-derived alkaloids still require much scientific research, and their actual efficacies for IBD patients have not been verified well in field research. Thus, further clinical trials to elu...

High-mobility group box 1 protein contributes to the immunogenicity of rTcdB-treated CT26 cells.
In this study, HMGB1 was found to be released from the rTcdB-treated CT26 cells. HMGB1 knockdown by using specific siRNA weakened the capacity of the BMDCs loaded with the rTcdB-treated CT26 cells to prime T cells in vitro and in vivo. The released HMGB1 from CT26 cells could interact with the receptor TLR4, which is closely related to DC activation and immune responses. The knockdown of HMGB1 also affected the phagocytosis of the rTcdB-treated CT26 cells by DCs in vitro. Furthermore, HMGB1 weakened the antitumor immunity of the rTcdB-treated CT26 cells, which protects mice from rechallenge of the live CT26 cells. Taken to...
