Combinational Targeting Offsets Antigen Escape and Enhances Effector Functions of Adoptively Transferred T Cells in Glioblastoma

Preclinical and early clinical studies have demonstrated that chimeric antigen receptor (CAR)-redirected T cells are highly promising in cancer therapy. We observed that targeting HER2 in a glioblastoma (GBM) cell line results in the emergence of HER2-null tumor cells that maintain the expression of nontargeted tumor-associated antigens. Combinational targeting of these tumor-associated antigen...

Coordination of T cell activation and migration through formation of the immunological synapse.

T cell activation is based on interactions of T cell antigen receptors with MHC-peptide complexes in a specialized cell-cell junction between the T cell and antigen-presenting cell-the immunological synapse. The immunological synapse coordinates naïve T cell activation and migration by stopping T cell migration with antigen-presenting cells bearing appropriate major histocompatibility complex (...

Engineered Jurkat Cells for Targeting Prostate-Specific Membrane Antigen on Prostate Cancer Cells by Nanobody-Based Chimeric Antigen Receptor

Background: Recently, modification of T cells with chimeric antigen receptor (CAR) has been an attractive approach for adoptive immunotherapy of cancers. Typically, CARs contain a single-chain variable domain fragment (scFv). Most often, scfvs are derived from a monoclonal antibody of murine origin and may be a trigger for host immune system that leads to the T-cell clearance. Nanobody is a spe...

ساخت گیرنده کایمریک لنفوسیت T دارای کمک محرک OX40 علیه سلول‌های سرطان سینه

Background and Objective: Chimeric antigen T cell receptors provide a good approach for adoptive immunotherapy of cancer. In this new kind of chimeric T cell receptor, nanobodies are replaced as variable fragment of T cell receptor. Nanobodies (VHH) are the smallest fragments of antibodies that have great homology to human VH and low immunogenic potential. VHH-hing-CD28-CD3و construct was made ...

TanCAR: A Novel Bispecific Chimeric Antigen Receptor for Cancer Immunotherapy

Targeted T cells are emerging as effective non-toxic therapies for cancer. Multiple elements, however, contribute to the overall pathogenesis of cancer through both distinct and redundant mechanisms. Hence, targeting multiple cancer-specific markers simultaneously could result in better therapeutic efficacy. We created a functional chimeric antigen receptor-the TanCAR, a novel artificial molecu...
