| 1 | Local sustained release of PD-1 monoclonal antibody and lenvatinib by thermo-sensitive hydrogel for improving tumor immunotherapy显示文摘In clinic,the combination of intravenous pembrolizumab(PD-1 monoclonal antibody)with oral Lenvatinib(LEN)exhibited an enhanced synergistic benefit for cancer therapy.However,the clinical outcomes were always limited by the problems of inconsistent pharmacokinetic profiles of two drugs,lower drug accumulation in tumor and obvious side effects during the combination therapy.Here,in situ-forming thermosensitive hydrogels based on PLGA-PEG-PLGA triblock copolymers were prepared for local administration of anti-PD1 and LEN(P&L@Gel)to improve therapeutic efficacy and safety.After peritumoral or surgical resection site injection,the significant increased concentrations of both drugs in tumor were observed with the local sustained release of P&L@Gel.In comparison with the group of intraperitoneal anti-PD1 plus oral LEN(P-ip&L-po),significantly higher tumor inhibition efficiency on CT26 tumor models could be obtained in P&L@Gel group,even at the dose of one-eighth of the former,same tumorinhibition effects could be achieved.The enhanced antitumor efficacy of P&L@Gel group was probably associated with the 2.2 folds of increased level of CD8+T cells and the polarization of tumor associated macrophage from M2 to M1 along with the increased drug accumulation.Moreover,compared with the obvious side effects of P-ip&L-po group,no significant changes of PLT,ALT and UA in blood,as well as IL-1αand IL-1βin mice paws were observed between P&L@Gel group and untreated group.These results suggested that local administration of anti-PD1 and LEN with thermosensitive hydrogel could offer a potential strategy for tumors or tumor postoperative adjuvant treatment. | Lin Zhai Yujie Shi Yi Yan An Lu Xiaoyu Liu Lei Lei Yi Sun Linxia Jiang Xiangyu Wang Honggang Qian Jiancheng Wang | 2023 | Chinese Chemical Letters2023，34，8： | 0 |
| 2 | Single-cell RNA-seq of Lotus japonicus provide insights into identification and function of root cell types of legume显示文摘The roots of legume plant play a crucial role in nitrogen fixation. However, the transcriptomes of different cell types of legume root and their functions remain largely unknown. Here, we performed single-cell RNA sequencing and profiled more than 22,000 single cells from root tips of Lotus japonicus, a model species of legume.We identified seven clusters corresponding to seven major cell types, which were validated by in situ hybridization. Further analysis revealed regulatory programs including phytohormone and nodulation associated with specific cell types, and revealed conserved and diverged features for the cell types. Our results represent the first single-cell resolution transcriptome for legume root tips and a valuable resource for studying the developmental and physiological functions of various cell types in legumes. | Zhanmin Sun Sanjie Jiang Dan Wang Linxia Li Boxin Liu Qifan Ran Lizhen Hu Junbo Xiong Yixiong Tang Xiaofeng Gu Yanmin Wu Zhe Liang | 2023 | Journal of Integrative Plant Biology2023，65，5： | 0 |
