Decreased immune response after PASylation of stealth ferritin nanocarriers
The effects on immunocompatibility after performed surface modifications (PEGylation
and PASylation) of natural nanocarriers based on ferritin (FRT) were tested in this work. Potential cytostatic drug ellipticine (Elli) was encapsulated into FRT, leading to formation of FRTElli. The main goals of prepared PEG-FRTElli, PAS-10-FRTElli and PAS-20-FRTElli were to achieve decreased in vitro macrophage uptake and decreased in vivo complement activation. Macrophage uptake was studied via flow cytometry and complement activation via western blot. According to performed experiments PAS-10 modification was the only one that was sufficient to ensure both aspects.
