Expression data from mouse CD19-targeted CAR (chimeric antigen receptor) T cells after antigen stimulation [RNA-seq]

Project description:Second-generation CD19-targeted chimeric antigen receptors (CAR) have an antigen-binding domain fused to transmembrane, co-stimulatory, and CD3ζ domains. The two CARs with regulatory approval include a CD28 or 4-1BB co-stimulatory domain. While both CARs achieve similar clinical outcomes, biologic differences between the two endodomains have become apparent but not completely understood. The objective is to evaluate gene expression in different mouse CD19-targeted CAR T cells, including m19z, m1928z and m19-humBBz.

Expression data from chimeric antigen receptor transduced (CAR) human CD4+ T cells during expansion

Project description:In this data set we include expression data from human CD4+ T cells isolated on day 0, 6, 11 and 24 follow anti-CD3/anti-CD28 magnetic bead stimulation and chimeric antigen receptor transduction. 30 samples were submitted. Samples represented three biological replicates of normal donors transduced with various CARs. CARs used were a cMet 28z specific CAR comprised of the IgG4 hinge, CD28 transmembrane and CD28 and CD3zeta intracellular domains. A CD19 CD28 CAR was specific to CD19, and was comprised of a CD8a hinge, CD28 transmembrane and CD28 and CD3zeta intracellular domain. A third CAR, the CD19 BBz, was used that was specific to CD19 was comprised of a CD8a hinge, CD8a transmembrane and 4-1BB and CD3zeta intracellular domains. Expression data was analyzied on day 0, 6, 11 and 24.

Proteomics analysis reveal early event molecular effectors of anti-CD19 CAR-T cell therapy in hematological cancer

Project description:Chimeric antigen receptor T-cell (CAR-T) therapy is at the forefront of cell immunotherapy. In this study, we generated an anti-CD19 CAR-Jurkat T cell line using a locally produced second-generation CD19 CAR construct, enabling us to analyze early proteomic changes crucial for understanding the signaling pathways and mechanisms of action of this CAR-T cell. SILAC-heavy tagged RAJI B-cells and anti-CD19 CAR-Jurkat T-cells were co-cultured for ten minutes. The proteomic profiles were obtained via DIA methodology on the Orbitrap Astral LC-MS/MS platform. The proteome was extensively covered, resulting in approximately 8800 protein identifications at 1% FDR. The effector CAR-Jurkat cells showed proteomic changes involving antigen presentation by CD74. The target RAJI B-cells exhibited more significant alterations, such as CD28, essential for T-cell survival and activation.

Gene expression profiles of CD4-derived (CAR4) and CD8-derived (CAR8) chimeric antigen receptor T cells after stimulation through the CAR, TCR or both receptors

Project description:Chimeric antigen receptor (CAR)-expressing T-cells induce durable remissions in patients with relapsed/refractory B-cell malignancies. CARs are artificial constructs introduced into mature T-cells conferring a second, non-MHC restricted specificity in addition to the endogenous T-cell receptor (TCR). The impact of TCR activation on CAR T-cell efficacy in vivo has important implications for clinical optimization of CAR T-cell therapy, but cannot be systematically evaluated in xenograft models. Using an immunocompetent, syngeneic murine model of CD19-targeted CAR T-cell therapy for pre-B cell ALL, we demonstrate loss of CD8 CAR T-cell mediated clearance of leukemia associated with T-cell exhaustion and apoptosis when TCR antigen is present. CD4 CAR T-cells demonstrate equivalent cytotoxicity, as compared to CD8 CAR T-cells, and in contrast, retain in vivo efficacy in the presence of TCR stimulation. Gene expression profiles confirm increased exhaustion and apoptosis of CAR8 upon dual receptor stimulation compared to CAR4, and indicate inherent differences in T-cell pathways. Chimeric antigen receptor (CAR) T cells express two activating receptors, the CAR and the endogenous T cell receptor (TCR). CAR T cells can be derived from either CD8 or CD4 T cells to generate CAR8 and CAR4 cells, respectively. In vivo, CAR8 and CAR4 cells respond differently when simultaneously stimulated through the CAR and TCR.

Phosphoproteomic analysis of successive Jurkat CD19-CAR generations reveals TCRζ-driven signalling

Project description:Although chimeric antigen receptor (CAR) T cell therapy has revolutionised individualised cancer therapies for relapsed/refractory lymphomas, low long-term retention due to basal signalling (antigen-independent activation in the absence of cognate antigen) and off-target toxicity limit the broad applicability of CAR-T products. During CAR development, researchers use model systems, like Jurkat T cells (Jurkats), to screen intracellular signalling arrangements based on their ability to activate (e.g., CD69 expression) and withstand repeated antigen encounters. Although Jurkats are standard for CAR screening, the mapping of CAR generations to Jurkat-specific pTyr networks relative to key TCR nodes and CD69 readouts is not well defined, blurring how hierarchical signalling drives activation. Here, we investigated how costimulation influenced tyrosine phosphorylation cascades using LC-MS/MS based phosphotyrosine (pY) proteomics and CD69 expression in the presence of small molecule inhibitors of key TCR signalling regulators. We found that including TCRζ (CD3ζ; gene CD247) in first (ζ-CAR), second (28ζ-CAR and BBζ-CAR), and third (28BBζ-CAR) generation CARs largely determined pY signalling, irrespective of costimulation. Further, we showed that the phosphatase activity of PTPN22 and SHP-1 were largely negligible for activation of CARs, but indiscriminate inhibition of phosphatases using pervanadate (PV) selectively activated BBζ-CARs without antigen encounter. Finally, we found that selective, partial inhibition of Itk using Soquelitinib reduced basal CD69 expression in CAR-Jurkat cells while maintaining their ability to activate in response to antigen. These data suggest that TCRζ determines the pY signalling profile and that Itk drives basal activation of CD19-CAR Jurkats, which may impact evaluation of new CAR designs in CAR-Jurkat screens.

Expression analysis of chimeric antigen receptor-transduced T cells following antigenic stimulation

Project description:Adoptive transfer of anti-CD19 chimeric antigen receptor (CAR)-engineered T cells has shown impressive clinical responses in patients with refractory B-cell malignancies. However, therapeutic effects of CAR-T cells targeting other hematologic malignancies and solid tumors are not yet satisfactory. Although inefficient tumor trafficking and multiple immunosuppressive molecules impede CAR-T cell effector responses, signals delivered by the current CAR constructs may still be insufficient to fully activate antitumor T cell functions. Optimal T cell activation and proliferation requires multiple signals including T cell receptor (TCR) engagement (signal 1), costimulation (signal 2), and cytokine engagement (signal 3). CAR genes developed to date contain a CD3z domain and costimulatory domain(s), but not a domain to transmit signal 3. In this study, we have developed a novel CAR construct capable of inducing cytokine signaling in an antigen-dependent manner. The new generation CD19 CAR encodes a cytoplasmic domain of IL-2RB and STAT3-binding YXXQ motif together with CD3z and CD28 domains (28-IL2RB-z (YXXQ)). The 28-IL2RB-z (YXXQ) CAR-T cells showed antigen-dependent JAK-STAT, especially the STAT3-mediated pathway activation, which promoted their proliferation and prevented terminal differentiation. The 28-IL2RB-z (YXXQ) CAR-T cells demonstrated superior in vivo persistence and antileukemia effects compared with the currently used CARs in multiple tumor models.
