PMID Cancer type Relation to immunity Evidence sentences
27693350Diffuse Large B-Cell Lymphoma Germinal Center B-Cell TypePromote immunityTo deliver solHVEM to lymphomas in vivo, we engineered CD19-targeted chimeric antigen receptor (CAR) T cells that produce solHVEM locally and continuously. These modified CAR-T cells show enhanced therapeutic activity against xenografted lymphomas.
27605551Refractory Non-Hodgkin LymphomaPromote immunity (T cell function)Immunotherapy with CD19 CAR-T cells in a defined CD4(+)/CD8(+) ratio allowed identification of correlative factors for CAR-T cell expansion, persistence, and toxicity, and facilitated optimization of lymphodepletion that improved disease response and overall and progression-free survival.
24623129Diffuse Large B Cell LymphomaPromote immunityDifferential role of Th1 and Th2 cytokines in autotoxicity driven by CD19-specific second-generation chimeric antigen receptor T cells in a mouse model. In summary, the adoptive transfer of second-generation CD19-specific CAR T cells can result in a cell dose-dependent acute toxicity, whereas the prolonged secretion of high levels of Th2 cytokines from these CAR T cells in vivo drives a granulomatous reaction resulting in chronic toxicity.
24500882Large B cell lymphomaPromote immunity (T cell function); essential for immunotherapyTargeting high-grade B cell lymphoma with CD19-specific T cells.
28576927Hodgkin LymphomaPromote immunityHowever, Hodgkin lymphoma lacks CD19 and contains a highly immunosuppressive tumor microenvironment (TME).
27571406B Acute Lymphoblastic LeukemiaPromote immunity (T cell function); essential for immunotherapyFinally, we devised a dual CAR-expressing construct that combined CD19- and CD123-mediated T cell activation and demonstrated that it provides superior in vivo activity against B-ALL compared with single-expressing CART or pooled combination CART. In conclusion, these findings indicate that targeting CD19 and CD123 on leukemic blasts represents an effective strategy for treating and preventing antigen-loss relapses occurring after CD19-directed therapies.
27460500Pre-B Acute Lymphoblastic LeukemiaPromote immunity (T cell function); essential for immunotherapyAdoptive immunotherapy using chimeric antigen receptor (CAR) expressing T cells targeting the CD19 B lineage receptor has demonstrated marked success in relapsed pre-B-cell acute lymphoblastic leukaemia (ALL). Using murine ALL models we study the long-term effects of CD19 CAR-T cells and demonstrate partial or complete lineage switch as a consistent mechanism of CAR resistance depending on the underlying genetic oncogenic driver. Deletion of Pax5 or Ebf1 recapitulates lineage reprogramming occurring during CD19 CAR pressure. Our findings establish lineage switch as a mechanism of CAR resistance exposing inherent plasticity in genetic subtypes of pre-B-cell ALL.
18227839Lymphoma; LeukemiaPromote immunity (T cell function); essential for immunotherapyIn order to test whether this system can be used for genetically modifying both PB T cells and umbilical cord blood (UCB) T cells as graft-versus-leukemia effector cells, an SB transposon was constructed to coexpress a single-chain chimeric antigen receptor (CAR) for human CD19 and CD20. The engineered CD4(+) T cells and CD8(+) T cells both exhibited specific cytotoxicity against CD19(+) leukemia and lymphoma cell lines, as well as against CD19 transfectants, and produced high-levels of antigen-dependent Th1 (but not Th2) cytokines. The in vivo adoptive transfer of genetically engineered T cells significantly reduced tumor growth and prolonged the survival of the animal.
25005243Acute Lymphoblastic LeukemiaPromote immunity (T cell function); increase the efficacy of immunotherapyIL-12-secreting CD19-targeted cord blood-derived T cells for the immunotherapy of B-cell acute lymphoblastic leukemia.
24919807leukemiaPromote immunityThe best example of this is represented by the anti-CD19 chimeric antigen receptor (CD19.CAR) T cells.
29685162Colon CarcinomaPromote immunityThe Food and Drug Administration has approved CAR T cells that target CD19 for treatment of advanced B cell leukemia and lymphoma.
29635163Acute Lymphoblastic LeukemiaPromote immunityCD19 loss is infrequent after blinatumomab, preserving the option for alternative CD19-direct treatments.
29633386acute lymphoblastic leukemiaPromote immunityA total of 18 R/R ALL patients with or without prior murine CD19 CAR-T therapy were treated with humanized CD19-targeted CAR-T cells (hCART19s).
29620951B-cell leukemia; lymphomaPromote immunityEarly trials with anti-CD19 CAR T cells have achieved spectacular remissions in B-cell leukemia and lymphoma, so far refractory, very recently resulting in the Food and Drug Administration approval of CD19 CAR T cells for therapy.
29605760lymphomaPromote immunityRemarkable responses have been observed in patients receiving autologous CD19-redirected T cells for the treatment of B-lymphoid malignancies.
27784674Acute Lymphoblastic LeukemiaPromote immunityResistance to anti-CD19/CD3 BiTE in acute lymphoblastic leukemia may be mediated by disrupted CD19 membrane trafficking. The CD19 antigen is a promising target for immunotherapy of acute lymphoblastic leukemia (ALL), but CD19- relapses remain a major challenge in about 10% to 20% of patients.
20110422B Acute Lymphoblastic LeukemiaPromote immunityWe have now generated CTL lines from peripheral blood (PB) or CB units that recognize multiple common viruses and provide antileukemic activity by transgenic expression of a chimeric antigen receptor (CAR) targeting CD19 expressed on B-ALL.
29334771Ovarian CancinomaPromote immunityCD19-targeted chimeric antigen receptor (CAR) engineered T/natural killer (NK)-cell therapies can result in durable clinical responses in B-cell malignancies.
29226764Diffuse Large B-Cell Lymphoma; Follicular LymphomaPromote immunityWe used autologous T cells that express a CD19-directed CAR (CTL019) to treat patients with diffuse large B-cell lymphoma or follicular lymphoma that had relapsed or was refractory to previous treatments. CTL019 cells can be effective in the treatment of relapsed or refractory diffuse large B-cell lymphoma and follicular lymphoma.
20668228Follicular LymphomaPromote immunityEradication of B-lineage cells and regression of lymphoma in a patient treated with autologous T cells genetically engineered to recognize CD19. The patient's lymphoma underwent a dramatic regression, and B-cell precursors were selectively eliminated from the patient's bone marrow after infusion of anti-CD19-CAR-transduced T cells.
20631379LymphomaPromote immunityAdoptive transfer of syngeneic T cells transduced with a chimeric antigen receptor that recognizes murine CD19 can eradicate lymphoma and normal B cells. Anti-CD19-CAR-transduced T cells eradicated intraperitoneally injected lymphoma cells and large subcutaneous lymphoma masses.

Content High-throughput screening data (e.g. CRISPR-Cas9, shRNA and RNAi) for T cell-mediated killing. Genetic screen techniques can identify mechanisms of tumor cell resistance (e.g., PTPN2) and sensitivity (e.g., APLNR) to killing by cytotoxic T cells, the central effectors of anti-tumor immunity. After comprehensively searching, eight groups of screening data sets were collected in the current database. In this tab, users can check whether their selected genes cause resistance or increase sensitivity to T cell-mediated killing in various data sets.
