Protein catenation potentiates antitumor activity of malaria VAR2CSA navigation CAR-T cells in a mouse model of hematological malignancies

Background
While CD19-targeting chimeric antigen receptor T-cell (CAR-T) therapies have shown efficacy in B-cell hematological malignancies, treatment of antigen-negative or relapsed tumors remains challenging. The recombinant malaria protein VAR2CSA …

Engineering TME-activated CD47-specific CAR macrophage via Arg1 promoter for safe and effective solid tumor immunotherapy

Background
Chimeric antigen receptor macrophage (CAR-M) therapy has promising therapeutic potential in solid tumors, yet challenges remain in target compatibility and systemic toxicity.

Methods
In this study, we screened the CD47-scFv sequence of CAR…

CAR-T cell therapy targeting MUC17 in gastric tumors

Background
Chimeric antigen receptor (CAR)-T cell therapy has achieved significant success in hematologic malignancies; however, its efficacy in solid tumors remains limited. A major limitation is the difficulty in identifying suitable target antigens…

JNK knockdown enhances CAR-T cell cytotoxicity through elevated NFATc1-dependent transcription in preclinical ovarian cancer models

Background
Boosting the performance of chimeric antigen receptor T (CAR-T) cell therapy in solid tumors may provide a substantial advantage for patients with cancer. Recognizing the vital role of the nuclear factor of activated T cells (NFAT) in T cel…

Increased NFAT activity with dual CAR stimulation in CD19xCD22 CAR T-cells is associated with decreased exhaustion and improved survival

Background
Chimeric antigen receptor (CAR) T-cell therapy is effective in treating B-cell malignancies, however relapse due to lack of CAR persistence and antigen-modulated escape remains common. Multiple strategies to simultaneously target CD19 and C…

Targeting the extracellular matrix with Tenascin-C-specific CAR T cells extends survival in preclinical models of glioblastoma

Background
Glioblastoma (GBM) is an aggressive brain tumor associated with poor outcome and limited treatment options. Chimeric antigen receptor (CAR) T cells targeting cell surface antigens were shown to induce tumor regression in patients with GBM, …

Acquisition of an immunosuppressive microenvironment after anti-CD19 CAR T-cell therapy is associated with T-cell dysfunction and resistance

Background
Chimeric antigen receptor (CAR) T cells targeting CD19 induce durable responses in B-cell acute lymphoblastic leukemia (B-ALL). However, the contribution of the tumor microenvironment to the therapeutic response after CAR T-cell treatment r…

Acquisition of an immunosuppressive microenvironment after anti-CD19 CAR T-cell therapy is associated with T-cell dysfunction and resistance

Background
Chimeric antigen receptor (CAR) T cells targeting CD19 induce durable responses in B-cell acute lymphoblastic leukemia (B-ALL). However, the contribution of the tumor microenvironment to the therapeutic response after CAR T-cell treatment r…

Macrophages expressing chimeric cytokine receptors have an inflammatory phenotype and antitumoral activity upon IL-10 or TGF{beta} stimulation

Background
Triple-negative breast cancer (TNBC) is a highly aggressive subtype of breast cancer that lacks hormone receptors and human epidermal growth factor receptor 2 (HER2) amplification, making it unresponsive to standard hormone or HER2-targeted…

Envirotune-CAR-T: a hypoxia-responsive and glutamine-enhanced CAR-T cell therapy for overcoming tumor microenvironment-mediated suppression

Background
Chimeric antigen receptor (CAR)-T cell therapy has demonstrated remarkable success in hematologic malignancies; however, its efficacy in solid tumors remains limited. A major barrier is the immunosuppressive tumor microenvironment (TME), wh…
