We then investigated the role of the murine analogue of human LILRB2, paired immunoglobulin-like receptor B (PirB, Lilrb3, Lir-3, Gp91; ENSMUSG00000058818, mouse chr7: 3,711,409-3,720,391(-)), in a myeloid-specific PirB-null Apoe−/− murine model of PAD. The gene discussed is LILRB2; the disease is peripheral arterial disease.
