As with intestinal IRI, Rag1-deficient mice are protected from cerebral IRI, and two IgM monoclonal antibodies were identified that reconstituted cerebral IRI in Rag1-deficient mice; these monoclonal antibodies recognized annexin IV and a subset of phospholipids, and thus identified danger-associated molecular determinants expressed after stroke in mice (71). The gene discussed is RAG1; the disease is stroke disorder.
