Publication number: 20230416326Abstract: A modified interleukin-2 (IL-2) molecule is obtained by being subjected to a modification as follows: substituting a region in an IL-2 molecule that mediates the binding of the IL-2 molecule to interleukin-2 receptor alpha (IL2R?) with a region in an interleukin-15 (IL-15) molecule that mediates the binding of the IL-15 molecule to interleukin-15 receptor alpha (IL15R?). The region in the IL-15 molecule that mediates the binding of the IL-15 molecule to the IL15R? includes 9 or more amino acid residues. Furthermore, a protein heterodimer including the modified IL-2 molecule and IL15R? (a Sushi domain) or a variant thereof is provided. The modified IL-2 molecule and/or the protein heterodimer including the modified IL-2 significantly reduce(s) an affinity of IL2R? to greatly reduce its side effects in clinical treatment and is promising drug candidate.Type: ApplicationFiled: October 16, 2021Publication date: December 28, 2023Applicant: LETO LABORATORIES CO., LTDInventors: Yao ZHAO, Yu ZHANG, Huijie LIU, Jinhua PIAO, Jianjun ZHANG, Qiulei ZHANG, Wei ZHANG, Guoyong WANG, Tianfu ZHANG

Publication number: 20210071142Abstract: The Invention relates to a MRFFT1 cell and a preparation method thereof. The Invention screens out mutant polypeptides with prediction of antigenic determinants, and links and synthesizes the expression gene sequences of mutant polypeptides. Meanwhile, the MVA virus vector is constructed to package MVA virus, and APC cells are transfected to complete the modification of specific MV cells, and PBMCs isolated from peripheral blood are co-cultured in vitro to screen out the effective polypeptide, and ordinary T cells is transformed into RFF cells with more precise killing through the second pulse of precise effective polypeptide stimulation. Then, the principle of TCR-T technology is used to modify the T cells, and gene coding technology is used to knock out the immunosuppressive target of the modified T cells. The specific killing T cells are precisely protected from in vivo inhibition, and the cytotoxicity of T cells to tumor cells is improved.Type: ApplicationFiled: March 13, 2019Publication date: March 11, 2021Applicant: BEIJING DCTY BIOTECH CO., LTD.Inventors: Shunchang Jiao, Rong Zhang, Zishan Zhou, Yuji Song, Jiasen Xie, Tianfu Zhang, Haiyan Wang, Han Yuan

Patent number: 9903002Abstract: The present invention provides Salmonella non-coding RNA and the identification and application thereof. In particular, the present invention proves through experiments that a Salmonella bacterium delivers non-coding RNAs (ncRNAs) encoded by the bacterium itself into a host cell, generates milRNAs similar to microRNAs by means of a microRNA splicing system in the cell, regulates the immune system with the milRNAs, and further protects the Salmonella bacterium from being cleared by the host. Adsorbing milRNAs using milRNA inhibitors can effectively inhibit the survival ability of the bacterium in the cell, leading to a reduced vitality of the bacterium. The present invention further provides relevant reagents and methods for effective detection of, treatment to and study on Salmonella bacteria or Salmonella infectious diseases.Type: GrantFiled: December 9, 2014Date of Patent: February 27, 2018Assignee: JIANGSU MICROMEDMARK BIOTECH CO., LTD.Inventors: Ke Zeng, Hongwei Gu, Chenyu Zhang, Tianfu Zhang
