Figure 2: Cytoplasmic CCR3 and CCR5 expression as assessed by immunofluorescence in control and IL-1β- treated RIN-5AH β-like cells. IL-1β significantly modified the cytoplasmic pools of CCR3 at 2 hours only, whereas significant modifications were obtained at 2, 4, 8 and 24 hours when cytoplasmic CCR5 expression was evaluated after IL-1β addition.
