Colocalization of free OVA^FITC, ^TCCSia‐Ace‐Dex‐OVA^FITC‐Rd (11), ^TCCSia‐Ace‐Dex‐OVA^FITC (12), PEG‐Ace‐Dex‐OVA^FITC‐Rd (13), PEG‐Ace‐Dex‐OVA^FITC (14), Ace‐Dex OVA^FITC/Rd (15), and Ace‐Dex OVA^FITC (16) within CD169⁺ bone marrow‐derived macrophages (BMMs) upon incubation with the nanoparticles (NPs; containing the same amount of OVA^FITC, 10 µg) for 6 h. The intracellular FITC signals were merged with Lysotracker (Lyso) Red, and the colocalization was shown in yellow. Scale bars: 10 µm.
