RAG2 and vascular disorder: Of note, no anti-Kd alloantibody was detected in the reconstituted BL/6 Rag2−/− SWHEL recipients (Figure 6C) and the simultaneously-transplanted BALB/c heart allografts survived until day 100, with development of mild vasculopathy and parenchymal injury, comparable in severity to that observed in similarly-reconstituted Rag2−/− recipients (Figures 5D, 6D).
