Mapping clinical CAR-T cells: insights from scRNA-seq
Abstract
Single cell RNA sequencing (scRNA-seq) has revolutionized the field of biology and become the most powerful tool for evaluating transcriptional profiles of a biological sample. Given its power, it is widely utilized across multiple disciplines, including chimeric antigen receptor (CAR)-T cell therapy. In this review, we provide a comprehensive summary of published studies that have used scRNA-seq to analyze clinical CAR-T cells, focusing on T cell exhaustion, cytotoxicity, memory, expansion, clonal diversity, and cytokines. We also highlight findings on activation, CD4+/CD8+ ratios, proliferation, regulatory T cells (Tregs) and metabolism, and their relevance to patient response across diseases. Finally, we discuss the limitations and future directions of scRNA-seq in CAR-T cell research, providing key insights for clinicians and researchers.
