Article Abstract
Glioblastoma is a highly aggressive and treatment-resistant primary brain cancer. While chimeric antigen receptor (CAR) T-cell therapy has demonstrated promising results in targeting these tumors, it has not yet been curative. An innovative approach to improve CAR T-cell efficacy is to combine them with other immune modulating therapies. In this study, we investigate combination of IL-13R2 targeted CAR T-cells with an oncolytic virus (OV) and study the complex interplay between tumor cells, CAR T-cells, and OV dynamics with a novel mathematical model. We fit the model to data collected from experiments with each therapy individually and in combination to reveal determinants of therapy synergy and improved efficacy. Our analysis reveals that the virus bursting size is a critical parameter in determining the net tumor infection rate and overall combination treatment efficacy. Moreover, the model predicts that administering the oncolytic virus simultaneously with, or prior to, CAR T-cells could maximize therapeutic efficacy.

Background And Objectives: Neuroimaging findings in immune effector cell-associated neurotoxicity syndrome (ICANS) have not been systematically described. We created the chimeric antigen receptor (CAR) T-cell Neurotoxicity Imaging Virtual Archive Library (CARNIVAL), a centralized imaging database for children and young adults receiving CAR T-cell therapy. Objectives of this study were to (1) characterize neuroimaging findings associated with ICANS and (2) determine whether specific ICANS-related neuroimaging findings are associated with individual neurologic symptoms.

T-cell therapies have proven to be a promising treatment option for cancer patients in recent years, especially in the case of chimeric antigen receptor (CAR)-T cell therapy. However, the therapy is associated with insufficient activation of T cells or poor persistence in the patient's body, which leads to incomplete elimination of cancer cells, recurrence, and genotoxicity. By extracting the splice element of PD-1 pre-mRNA using biology based on CRISPR/dCas13 in this study, our ultimate goal is to overcome the above-mentioned challenges in the future.

Large B cell lymphomas (LBCL) are clinically and biologically heterogeneous lymphoid malignancies with complex microenvironments that are central to disease etiology. Here, we have employed single-nucleus multiome profiling of 232 tumor and control biopsies to characterize diverse cell types and subsets that are present in LBCL tumors, effectively capturing the lymphoid, myeloid, and non-hematopoietic cell compartments. Cell subsets co-occurred in stereotypical lymphoma microenvironment archetype profiles (LymphoMAPs) defined by; (1) a sparsity of T cells and high frequencies of cancer-associated fibroblasts and tumor-associated macrophages (FMAC); (2) lymph node architectural cell types with naive and memory T cells (LN); or (3) activated macrophages and exhausted CD8 T cells (TEX).

Antibody-based therapies have revolutionized cancer treatment but have several limitations. These include: down-regulation of the target antigen; mutation of the target epitope; or in the case of antibody drug conjugates (ADCs), resistance to the chemotherapy warhead. Since TROP2-targeted therapy with ADCs yields responses in TROP2+ solid tumors but lacks the durability observed with other immunotherapy-based approaches, we developed novel TROP2-targeting chimeric antigen receptor (CAR) T cells as an alternative.

Metastatic and relapsed osteosarcoma (OS) remains difficult to treat despite advanced surgical techniques, intensified chemotherapy, and targeted therapies. Adoptive immunotherapies such as chimeric antigen receptor (CAR) T cells, are in their nascent stage, but remain a viable therapeutic strategy for patients with aggressive solid tumors such as OS. Folate receptor- (FOLR1) has been functionally implicated in OS pathophysiology, providing rationale as a potential therapeutic target.
