Single-cell transcriptomic sequencing of BCMA CAR-T cells during CAR-T therapy in refractory primary plasma cell leukemia

Project description:Chimeric antigen receptor T-cell (CAR-T) therapy has revolutionized the clinical treatment of hematological malignancies due to the prominent anti-tumor effects. B-cell maturation antigen (BCMA) CAR-T cells have demonstrated promising effects in patients with relapsed/refractory multiple myeloma. However, the dynamics of CAR-T cell proliferation and cytotoxicity in a patient remains largely unexplored. Single-cell RNA sequencing samples were collected at three phases: CAR-T products before infusion, CAR-T on day 8 after infusion, and CAR-T on day 15 after infusion. After obtaining the PBMCs for each phase, CAR-T and endogenous T cells were collected by fluorescence-activated cell sorting with anti-Mouse IgG Biotin, FITC Streptavidin, and anti-human CD3 APC.

Single cell RNA sequencing of CD45.2+ endogenous immune cells following treatment with CAR-T cells

Project description:The goal of this study was to assess the consequences of RNA delivery via CAR-T cell on endogenous immune cells within the B16 tumor microenvironment. RN7SL1 RNA-producing CAR-T cells are the relevant experimental condition, while control scramble RNA and No RNA 19BBz CAR-T cells are also included.

Analysis of the transcriptomic profiles for HER2 CD8+ CAR T cells-overexpressed FOXO1WT

Project description:T cell exhaustion and metabolic dysfunction induced by chronic antigen stimulation within the tumor microenvironment represent formidable obstacles in CAR T cell therapy for solid tumors. Previously, we developed a method to convert effector/exhausted CAR T cells that emerge from repeated antigen stimulation into stem cell memory-like CAR T (termed CAR-iTSCM) cells. These CAR-iTSCM cells exhibit expression of early memory markers and enhanced mitochondrial metabolism after quiescence under culture conditions containing IL-7, CXCL12, and the NOTCH-ligand. However, we noticed that this strategy was effective for CD19 CAR used for blood cancers, but not for HER2 CAR commonly used to treat solid tumors, due to tonic CAR signals. In this study, we developed a new culture condition for CAR iTSCM cells suitable for HER2 CAR and elucidated the mechanism of induction of stemness and mitochondrial fitness. We found that short-term resting condition with IL-7, CXCL12, and pan-tyrosine kinase inhibitor, Dasatinib can induce stem-like CAR T cells at the epigenetic level and enhance mitochondrial metabolism. We identified FOXO1 as a critical regulator in the process of epigenetic and metabolic reprogramming, and anti-tumor activity. We found that overexpression of FOXO1 leads to enhanced mitochondrial metabolism, efficient CAR T cell expansion, and potent anti-tumor effects through epigenetic modifications. These findings suggest that regulating the transcriptional activity of FOXO1 is a promising strategy for engineering effective CAR T cells for treating solid tumors. In this analysis, we aimed to investigate the effects of FOXO1WT overexpression on the transcriptomic profiles in 4-1BB-based HER2 CD8+ CAR T cells which exhibit tonic signals-induced exhaustion hallmarks.

single cell RNA-sequencing analysis of human SUV39H1-knockout CAR T compared to control CAR T cells (mock) in a xenograft model of lung adenocarcinoma

Project description:We have observed that the inactivation of SUV39H1 enhances 41BBz-CAR T cell long-term persistence, providing protection against tumor relapses and rechallenges in a xenograft mouse model of lung adenocarcinoma. The purpuse of this study is to investigate the transcriptomic differences of lung-infiltrating SUV39H1 knock-out versus mock 41BBz-CAR T cells by single cell RNA sequencing at days 8 and 28 after CAR T cell infusion.

The role of a novel CAR-induced gene TUBA8 in hepatocellular carcinoma cell lines

Project description:The Tuba8 gene was identified as a CAR-regulated gene that was induced during phenobarbital (PB) promotion of liver tumor. TUBA8 was then over-expressed in heaptocarcinoma cells to determine the function of TUBA8. First, identify genes that are regulated by CAR and are induced during liver tumor development. Second, overexpressiong of an identified gene in transformed cells to detemine the biolgical function of the gene product. In this manuscript, the TUBA8 gene was examined.

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.

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

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.
