| 1 | Induced regulatory T cells suppress Tel cells through TGF-β signaling to ameliorate STZ-induced type 1 diabetes mellitus显示文摘Type 1 diabetes mellitus(T1D)is a chronic autoimmune condition in which the immune system destroys insulin-producing pancreatic β cells.In addition to well-established pathogenic effector T cells,regulatory T cells(Tregs)have also been shown to be defective in T1D.Thus,an increasing number of therapeutic approaches are being developed to target Tregs.However,the role and mechanisms of TGF-β-induced Tregs(iTregs)in T1D remain poorly understood.Here,using a streptozotocin(STZ)-induced preclinical T1D mouse model,we found that iTregs could ameliorate the development of T1D and preserve β cell function.The preventive effect was associated with the inhibition of type 1 cytotoxic T(Tel)cell function and rebalancing the Treg/Tc1 cell ratio in recipients.Furthermore,we showed that the underlying mechanisms were due to the TGF-β-mediated combinatorial actions of mTOR and TCF1.In addition to the preventive role,the therapeutic effects of iTregs on the established STZ-T1D and nonobese diabetic(NOD)mouse models were tested,which revealed improved β cell function.Our findings therefore provide key new insights into the basic mechanisms involved in the therapeutic role of iTregs in T1D. | Li Zhou Xuemin He Peihong Cai Ting Li Rongdong Peng Junlong Dang Yue Li Haicheng Li Feng Huang Guojun Shi Chichu Xie Yan Lu Yanming Chen | 2021 | Cellular & Molecular Immunology2021，18，3： | 3 |
| 2 | Discovery and bioassay of disubstituted β-elemene-NO donor conjugates:synergistic enhancement in the treatment of leukemia显示文摘Natural products are essential sources of antitumor drugs.One such molecule,β-elemene,is a potent antitumor compound extracted from Curcuma wenyujin.In the present investigation,a series of novel 13,14-disubstituted nitric oxide(NO)-donorβelemene derivatives were designed,withβ-elemene as the foundational compound,and subsequently synthesized to evaluate their therapeutic potential against leukemia.Notably,the derivative labeled as compound 13d demonstrated a potent anti-proliferative activity against the K562 cell line,with a high NO release.In vivo studies indicated that compound 13d could effectively inhibit tumor growth,exhibiting no discernible toxic manifestations.Specifically,a significant tumor growth inhibition rate of 62.9%was observed in the K562 xenograft tumor mouse model.The accumulated data propound the potential therapeutic application of compound 13d in the management of leukemia. | ZHU Junlong JIANG Xiaoying LUO Xinyu GAO Yuan ZHAO Rui LI Junjie CAI Hong DANG Xiawen YE Xiangyang BAI Renren XIE Tian | 2023 | Chinese Journal of Natural Medicines2023，21，12： | 1 |
