HLA-independent T-cell receptors (TCRs) with specific reactivity against the urokinase receptor (uPAR) provide a novel approach for targeted immunotherapy.
Unlike conventional TCRs, these receptors directly recognize uPAR on the cell surface and do not require HLA presentation or antigen processing, which may enable broader applicability across patient populations.
The anti-uPAR TCRs were isolated from healthy blood donors and include candidates recognizing both cell-surface forms of uPAR. They are functional in both CD4 and CD8 T cells, show avidity comparable to neoantigen-specific HLA-restricted TCRs, and demonstrate robust cytolytic activity against target cells.
