TLR4 was localized to the plasma membrane of non-stimulated (Figure 4a,c) and 40 min LPS-stimulated (Figure 4e,g) control macrophages but not AAA macrophages in either the non-stimulated (Figure 4m,o) or LPS-stimulated (Figure 4q,s) conditions. This evidence concerns the gene TLR4 and triple-A syndrome.
