RNA-seq on CAR-T cells and CAR-T cells exposed to Nalm6 stimulation followed by treatment with DMSO, BAPTA and BTP-2

ABSTRACT: Chimeric antigen receptor (CAR) T cells are known to be potent in recognizing and eliminating tumor elimination, and effector functions. They induce marked responses in patients with refractory leukemia and lymphoma, but dysfunction of T cells is an inevitable obstacle for persistent curative effect. Extending the persistence of these cells without compromising their potency is supposed to improve treatment outcomes. We demonstrated that the SOCE (Store-Operated Calcium Entry) inhibitor BTP-2, rather than calcium chelator BAPTA-AM, diminished exhaustion and terminal differentiation of CAR-T cells both in tonic signaling and tumor antigen exposure models. And BTP-2 pretreated CAR-T cells showed improved antitumor potency and prolonged survival in NSG mice. To further investigate the biological impact of calcium signaling at the molecular level, we performed RNA-seq on CAR-T cells and CAR-T cells exposed to Nalm6 stimulation followed by treatment with DMSO, BAPTA and BTP-2.The high-throughput RNA sequencing (RNA-Seq) revealed that treatment with BTP-2 downregulates glycolysis pathway.

UPenn CAR T cell Responders and Non-responders

Project description:<p>The adoptive transfer of autologous T cells genetically modified to express a CD19-specific, 4-1BB/CD3zeta-signaling chimeric antigen receptor (CAR; CTL019) has shown remarkable activity in patients with B acute lymphoblastic leukemia. Similar therapy can induce long-term remissions for relapsed/refractory chronic lymphocytic leukemia (CLL) patients, but in only a small subset of subjects. The determinants of response and resistance to CTL019 therapy of CLL are not fully understood. We employed next generation sequencing of RNA (RNA-seq) to identify predictive indicators of response to CTL019 treatment. We performed RNA-seq on leukapheresis and manufactured infusion product T cells from patients with heavily pre-treated and high-risk disease. To characterize potency, we also performed RNA-seq on the cellular infusion product after CAR-specific stimulation. Our findings indicate that durable remission in CLL is associated with gene expression signatures of early memory T cell differentiation (e.g., STAT3), while T cells from poorly- or non-responding patients exhibited elevated expression of key regulators of late memory as well as effector T cell differentiation, apoptosis, aerobic glycolysis, hypoxia and exhaustion. These gene expression signatures, along with additional immunological biomarkers, may be used to identify which patients are most likely to respond to cellular therapies and suggest manufacturing modifications that might potentiate the generation of maximally efficacious infusion products.</p>

An immunoproteomic approach to characterize the CAR interactome and signalosome

Project description:Adoptive transfer of chimeric antigen receptor (CAR)-T cells is expected to become the first line of treatment for multiple malignancies, following the enormous success of anti-CD19 therapies. However, their mechanism of action is not fully understood, and clear guidelines for the design of safe and efficient receptors are missing. We hereby describe a systematic analysis of the CAR “signalosome” in human primary T cells. Two CAR designs were compared: a second-generation (PSCA2) and a third-generation (PSCA3) anti-PSCA CAR. Phosphorylation events triggered by CAR-mediated recognition of target cells were quantified by mass spectrometry.

The Second Generation of CAR-iMACs with Enhanced Polarization, CAR-mediated Efferocytosis and Superior Potency against Solid Tumors

Project description:Chimeric antigen receptor (CAR)-T cell therapies have shown great success in treating hematologic malignancies. Nonetheless, their therapeutic effect on solid tumors remains to be improved. Recently, macrophages have attracted great attention, given their ability to infiltrate solid tumors, phagocytize tumor cells as well as their immunomodulatory capacities. The first generation of CD3ζ-based CAR-macrophages demonstrated that the CAR could stimulate macrophage phagocytosis in a tumor antigen-dependent way. Here, we genetically engineered induced pluripotent stem cell (iPSC)-derived macrophages (iMACs) with TLR4 intracellular TIR domain-containing CARs against EGFRvIII and GPC3, which yielded markedly enhanced antitumor effect in two different solid tumor models including glioblastoma, and hepatocellular carcinoma in which complete remission was achieved with CAR-iMACs alone or in combination with CD47 antibody. Moreover, the tandem CD3ζ-TIR-CAR, or the “second-generation” design of TIR-based dual signaling CAR, endowed iMACs with both target engulfment/efferocytosis capacity against antigen-expressing solid tumor cells, and potency of antigen-dependent M1 state polarization and M2 state resistance in an NF-κB dependent manner. We also illustrated a surprising mechanism of tumor cell elimination by CAR-induced efferocytosis against tumor cell apoptotic bodies. Taken together, we established the next generation CAR-iMACs equipped with orthogonal phagocytosis and polarization capacity for better antitumor functions in treating solid tumors.

Transfer of antigen target into CAR T cells via trogocytosis

Project description:To characterize transfer of molecules from target cells into CAR T cells via trogocytosis we cultured NALM-6 leukemia cell line expressing a CD19-mCherry fusion protein with CAR T cells. NALM6-CD19-mCherry were loaded with heavy amino acid and cocultured with CAR T cells for 1 hour. CAR T cells were next sorted into two fractions, mCherry-positive (TrogPos), and -negative (TrogNeg). Proteomics analysis revealed the presence of targeted antigen (CD19) in the TrogPos only.

Bulk mRNA Seq CAR.CCR7 vs. CAR

Project description:The study aimed to elucidate the transcriptional changes introduced by genetic engineering of CAR T cells to stably express the homeostatic chemokine receptor CCR7. In vitro killing assays hinted to a higher cytolytic capacity that could be tied to an altered cytoskeletal rearrangement. Human CAR and CAR.CCR7 T cells were generated by retroviral transduction and enriched by FACS at the end of the expansion phase (day 10), either without or with a previous over-night co-culture with target Jeko1 tumor cells that express the CAR target antigen CXCR5. Enriched cells were immediately processed for bulk mRNA Seq

Augmenting CAR T Cell Function with LIGHT

Project description:Chimeric antigen receptor (CAR) T cell therapy has shown remarkable clinical success in the treatment of B-cell acute lymphoblastic leukemia (B-ALL), non-Hodgkin lymphoma (NHL), and multiple myeloma (MM), but its clinical efficacy in other hematologic tumors and solid tumors has been modest. Some of the major challenges that diminish the efficacy of CAR T cells against solid tumors are tumor-associated antigen heterogeneity and the immunosuppressive tumor microenvironment (TME). To overcome these problems, we developed CAR T cells overexpress with LIGHT (TNFSF14), which is a ligand of both LtβR (lymphotoxin beta receptor) on cancer cells and HVEM (herpes virus entry mediator) on immune cells. In addition to the cancer cell-directed cytotoxicity mediated by the CAR T cells themselves, the interaction of LIGHT with LTβR on tumor cells led to antigen-independent killing; moreover, LIGHT also provided immunostimulatory properties to the T cells. Hence, LIGHT-CAR T cells promoted, through multimodal and orthogonal mechanisms, an improved antitumor response through enhanced tumor killing and costimulatory potential. The antigen-independent killing of heterogeneous cancer cells was widely applicable across various cancer cell lines and was mediated by LIGHT CAR T cells in an LTβR-dependent manner. In addition, LIGHT-CAR T cells demonstrated higher proliferative capacity and proinflammatory cytokine secretion than non-LIGHT expressing CAR T cells. Furthermore, LIGHT-CAR T cells conferred significant tumor control and concomitant survival benefit as compared to non-LIGHT CAR T cells in xenograft models of solid tumors with a heterogeneous expression of the target antigen. The application of LIGHT-CAR T cell therapies may provide a novel therapeutic approach to the treatment of solid tumors in the context of antigen-heterogeneous disease thereby preventing outgrowth of antigen-negative populations leading to disease relapse.

Targeted scRNA-seq and AbSeq of human CAR-T cell infusion product from 28 cancer patients

Project description:Immunotherapy using CD19-directed chimeric antigen receptor (CAR)-T cells has shown excellent results for treatment of B-cell leukaemia and lymphoma. To produce CAR-T cells, the patient’s own T cells are isolated from the blood and modified in a laboratory with a genetic vector to express a tumor antigen-directed CAR on its surface. The CAR-T cells are then expanded in numbers and given back to the patient with the aim to eradicate the tumors. However, some patients display primary resistance to CAR-T treatment while others relapse quickly after CAR-T treatment. In this experiment, we seek to understand whether the quality of the individual CAR-T cell product the patients were given can predict outcome to the therapy. We investigate the transcriptional profile of the individual CAR-T infusion products using single-cell RNA sequencing. In this dataset, we identified a T cell subset correlating with response that could be used as an indicator for clinical outcome. Targeted RNA and protein single-cell libraries were obtained using the BD Rhapsody platform (BD Biosciences). In total four separate targeted libraries were produced with 6 patients per library. Sequencing was performed on NovaSeq 6000 S1 sequencer at the SNP&SEQ Technology Platform (Uppsala, Sweden). The raw scRNA-seq data was pre-processed by BD Biosciences using the Rhapsody Analysis pipeline to convert the raw reads into Unique Molecular Identifier (UMI) counts. UMIs are further adjusted within Rhapsody by applying BD’s Recursive Substitution Error Correction (RSEC) and Distribution-Based Error Correction (DBEC) in order to remove false UMIs caused by sequencing or library preparation errors. Pooled samples were deconvoluted using Sample-tag reads. The scRNA-seq and AbSeq counts were loaded, processed and used for clustering and differential gene expression with Seurat v. 4.0.0.

CAR T cells inhibit B cell activating phosphorylation in their targets

Project description:Adoptive cell therapy, a subset of cancer immunotherapy, is collection of therapeutic approaches which aim to redirect the immune system by reprogramming patient T-cells to target antigenic molecules differentially and specifically expressed in certain cancers. One promising immunotherapy technique is CAR T-cell therapy, where cancer cells are targeted through the expression a chimeric antigen receptor (CAR), a synthetic trans- membrane receptor that functionally compensates for the T-cell receptor (TCR) but targets a tumor associated antigen on the cancer cell surface. While CAR T-cell therapy is promising with two clinically approved second-generation CARs (Kymriah and Yescarta), few studies have investigated the mechanism of signal propagation in T-cells and no studies have investigated the potential signaling response in the target cells. To gain further insight to CAR-based signaling, we stimulated third generation CD19 CAR-expressing Jurkat T-cells by co-culture with SILAC labeled CD19HI Raji B-cells and used two phosphoenrichment strategies coupled with liquid chromatography-tandem mass spec- trometry (LC-MS/MS) to detect and analyze global phosphorylation changes in both cell populations. Analysis of the phosphopeptides originating from the CD19-CAR T cells revealed an increase in many phosphorylation events necessary for canonical TCR signaling. We also observed for the first time a significant decrease in B-cell receptor- related phosphopeptide abundance in CD19HI Raji B-cells after co-culture with CD19-targetted CAR T-cells.
