Single–gene knockout of RNLS or HIVEP2 are insufficient to protect β–cell spheroids from allo– and xeno–rejection

These data indicate that single-gene deletions of RNLS or HIVEP2 are insufficient to protect β-cell grafts from the barriers of allo- or xenorejection. By defining the limitations of these targets in isolation, our findings highlight the necessity for combinatorial genome editing strategies or complementary integration with immunomodulatory biomaterials to achieve effective and sustained β-cell graft survival.
