摘要: 一种经修饰的免疫效应细胞,其中所述经修饰的免疫效应细胞中的T细胞抗原受体(TCR)和主要组织相容性复合体(MHCI,MHCII)在T细胞中的功能受到抑制,且所述经修饰的免疫效应细胞包含靶向GD2的嵌合抗原受体(CAR)。经修饰的免疫效应细胞,识别肿瘤细胞表面抗原的同时,敲除细胞表达的TCR和HLA-A基因,达到提高CAR-T细胞的抗肿瘤作用,延长细胞存活时间,同时降低同种异体细胞治疗引起的免疫排斥反应的多重效果。

摘要: This disclosure describes a nucleic acid construct that contains sequences for an Endotope construct, a STAT1c, and miR142 target sites. In one example, disclosed is composition comprising an Endotope construct and a STAT1 construct including a nucleic acid sequence encoding a constitutively active STAT1 (e.g. STAT1c), wherein the Endotope and the STAT1 constructs each include miR142 target sites. In alternative examples, disclosed is a single construct that includes the Endotope construct and STAT1 construct along with miR142 target sites. The nucleic acid constructs can be packaged into polycationic molecules or liposome to create nanoparticles for efficient cell transfection.

摘要: Particular interest has arisen regarding the therapeutic potential of regulatory T cells (Tregs) in ischemic stroke. However, the ex vivo-expansion of Tregs usually takes several weeks to achieve a target number of cells. Allogeneic (off-the-shelf) Tregs would be desirable, but are limited by acute graft-versus-host disease (GVHD). As disclosed herein, CD83 is differentially expressed on alloreactive T cells. Therefore, disclosed herein are immune effector cells genetically modified to express a chimeric antigen receptor (CAR) polypeptide targeting CD83 that are capable of suppressing this alloreactivity. In some embodiments, the immune effector cell is used in combination with an autologous Treg therapy. In other embodiments, the autologous Treg is itself genetically modified to express the CAR polypeptide targeting CD83.

摘要: The gene preparation consists of a recombinant adeno-associated virus serotype 9 containing a codon-optimized ARSA gene sequence. Gene-cell preparation consists of mesenchymal stem cells genetically modified with recombinant adeno-associated virus serotype 9 containing a codon-optimized ARSA gene sequence. A method for treating metachromatic leukodystrophy using a gene preparation consists in intravenous or intrathecal administration of a recombinant adeno-associated virus serotype 9 containing a codon-optimized ARSA gene sequence. A method for treating metachromatic leukodystrophy using a gene-cell drug consists in the intravenous administration of mesenchymal stem cells genetically modified with a recombinant adeno-associated virus of serotype 9 containing a codon-optimized ARSA gene sequence.
