Regulatory T (T) cells are a suppressive subset of CD4 T cells that maintain immune homeostasis and restrain inflammation. Three decades after their discovery, the promise of strategies to harness T cells for therapy has never been stronger. Multiple clinical trials seeking to enhance endogenous T cells or deliver them as a cell-based therapy have been performed and hint at signs of success, as well as to important limitations and unanswered questions.
View Article and Find Full Text PDFTregs expressing chimeric antigen receptors (CAR-Tregs) are a promising tool to promote transplant tolerance. The relationship between CAR structure and Treg function was studied in xenogeneic, immunodeficient mice, revealing advantages of CD28-encoding CARs. However, these models could underrepresent interactions between CAR-Tregs, antigen-presenting cells (APCs), and donor-specific Abs.
