Representative photomicrographs showing immunohistochemical stainings for MOMA-2 (macrophage) (dark red in a, b) and CD3 (lymphocytes) (red dots in c, d) in transversal sections from the aortic sinus of CCR1^+/+ (a, c) and CCR1^−/− (b, d) mice. We found a 30% increase in macrophage content and a persistent substantial accumulation of T cells in lesions of CCR1^−/− mice. Original magnifications × 200.
