In situ generation of proinflammatory CAR macrophages via mRNA-TLR agonist co-delivery for triple-negative breast cancer immunotherapy

Background
Chimeric antigen receptor (CAR) macrophage therapy shows significant potential for solid tumors owing to the intrinsic tumor infiltration and phagocytic capacity of macrophages. However, its clinical translation is limited by macrophage phe…

Sleeping Beauty mutagenesis identifies BACH2 and other regulators of CD8+ T-cell exhaustion, persistence in vivo, and CAR-T cell function under tumor-associated chronic antigen stimulation

Background
Genes that enhance T-cell function represent promising targets for improving engineered T-cell therapies for cancer. While extensive CRISPR knockout screens have identified key genes enhancing T-cell persistence, employing Sleeping Beauty (…

Unbiased avidity-based isolation of antigen-specific T cells

Background
Cancer immunotherapies have significantly improved treatment efficacy and patient survival by exploiting antigen-specific T cells to eliminate cancer cells. However, current approaches for identifying and isolating antigen-specific T cells …

Circumventing Ewing sarcoma tumor microenvironment resistance by IL1RAP CAR-modified TGF{beta}1-imprinted natural killer cells in combination with IL-15 agonist and anti-GD2 antibody

Background
The prognosis of patients with metastatic/relapsed/refractory Ewing sarcoma (ES) is dismal. Natural killer (NK) cells are highly cytotoxic to ES but limited by resistance within the ES tumor microenvironment (TME). Here we sought to overcom…

ENPP3 CAR T cells combined with CD206 modulation suppress adrenocortical carcinoma

Background
Adrenocortical carcinoma (ACC) is a rare and aggressive malignancy with poor prognosis and limited curative treatment options. While chimeric antigen receptor (CAR) T cells have shown some promise in solid tumors, ACC remains largely unexpl…

Chimeric switch scaffold protein augments CAR synapse formation and signaling networks

Background
Chimeric antigen receptor (CAR) T-cell therapy has achieved clinical success in hematologic malignancies, but remains limited in solid tumors due to immune checkpoint-mediated suppression and intrinsic signaling constraints. Unlike T-cell r…

Differential cytokine architecture in patients treated with CART19 versus CART22

Background
Cytokine release syndrome (CRS) is a life-threatening toxicity of chimeric antigen receptor T-cell therapy (CART) for B-cell acute lymphoblastic leukemia (B-ALL). Lower rates of severe CRS have been reported in patients treated with CD22-di…

Integrin CD11b/CD18 reprograms macrophage polarization by suppressing ERK/STAT3 signaling to enhance antitumor immunity in colitis-associated colorectal cancer

Background
Chronic inflammation is a well-established driver of colorectal cancer (CRC), with the resulting inflammatory microenvironment facilitating tumor initiation and progression. The integrin CD11b/CD18, a leukocyte-specific heterodimeric adhesi…

Novel CAR T cell blend targeting PDPN and GD2 to overcome glioblastoma heterogeneity

Background
While chimeric antigen receptor (CAR) T cells have achieved encouraging remission rates in hematological malignancies, they have demonstrated limited success in treating glioblastoma (GBM), particularly due to high intratumoral and intertum…

Systemic pre-conditioning favors effector over exhausted CD8 T-cell subsets following Sup2-IL33 armored CAR T-cell therapy

Background
Systemic pre-conditioning prior to chimeric antigen receptor (CAR) T-cell infusion enhances engraftment and increases infiltration and activity of adoptively transferred cells within the tumor. Despite promising responses in some patients, …
