Rapid tumor regression from PD-1 inhibition after anti-CD19 chimeric antigen receptor T-cell therapy in refractory...

Here, we describe an in vitro co-culture method to recursively challenge tumor-targeted T cells, which allows for phenotypic and functional analysis of antitumor T cell...

This protocol provides a streamlined workflow to generate and test human chimeric antigen receptor regulatory T cells (CAR...

This video demonstrates a technique for the ex vivo generation of tumor antigen-specific chimeric antigen receptor (CAR) T cells. Retroviral vectors carrying transgenic RNA are mixed with spleen cells in a medium supplemented with interleukin-2 to promote T-cell survival and proliferation. The mixture is then transferred to a plate coated with recombinant human fibronectin fragments and centrifuged to facilitate the fusion of the virus with the cell, allowing the RNA to integrate into the host...

This video demonstrates an in vitro assay to validate chimeric antigen receptor (CAR) T cell activity. B-cell lymphoma cells expressing CD19 antigen and cytoplasmic luciferase are co-cultured with CD19-specific CAR T cells. CAR binding to CD19 on a tumor induces the CAR T cells to release cytokines and toxins that cause tumor cell cytotoxicity. The CAR T cell activity is evaluated by quantifying the released cytokine and decreased luciferase-mediated bioluminescence in the tumor...

This video demonstrates a technique to manufacture chimeric antigen receptor (CAR) T cells ex vivo. Human T cells are incubated with magnetic beads coated with anti-CD3 and anti-CD28 antibodies, along with a medium supplemented with interleukin-2 (IL-2), leading to T cell activation and proliferation. Transgenic lentiviral vectors are introduced, allowing the transgenic RNA to integrate into the host genome and express the transgene. This results in the transduced T cells expressing chimeric...

Mantle cell lymphoma (MCL) is a difficult to treat B cell disorder and it is equally difficult to establish a xenograft mouse model of primary MCL to study and develop therapeutics. Here, we describe the successful establishment of MCL xenografts in mice to help understand its underlying...
