Towards 'Off-the-Shelf ' Universal Chimeric Antigen Receptor (CAR) T Cells: Mouse Anti-3rd Party Central Memory CD8 Veto Cells Prolong Functional Engraftment of Allogeneic Genetically Modified T Cells
Abstract:We recently demonstrated that mouse anti-3rd party central memory CD8 veto cells (Tcm) enable engraftment of fully mis-matched T cell depleted bone marrow (TDBM) in sublethally irradiated (5.5 Gy TBI) recipients (Eran et al. Blood 2013). Here we found that Tcm generated from (host x donor)F1 or fully allogeneic donors were able to engraft and sustain their presence in such sub-lethally irradiated mice in the absence of TDBM transplants. Limiting dilution analysis revealed that the reactivity of host T cells (H… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
