Abstract

The blending system of chitooligosaccharide (COS) and polyethyleneimine (PEI) was studied as a drug carrier for tumor treatment. Nanoparticles COS/PEI-PolyI:C-OVA-x (CP-P-O-x) (x=1, 2, 3) were prepared by electrostatic self-assembly of COS and PEI with the immune enhancing drug PolyI:C and the mimic antigen ovalbumin (OVA) using different feeding methods. The results showed that the nanoparticle solution could be stable only when the concentration of the added PEI was above 5.0% w/w. PolyI:C could be coated well and protected from nuclease degradation. The OVA encapsulation efficiency was above 75%. The results of cell viability experiments showed that the blend of COS and PEI had low cytotoxicity. The CP-P-O-1 had a suitable particle size, which was easy to be absorbed and expressed by cells. The results of in vitro immunization showed that due to the addition of PolyI:C, whether OVA was loaded on the inside or on the surface, nanoparticles significantly promoted the secretion of cytokines mouse tumor necrosis factor α (TNF-α) and mouse interferon-γ (IFN-γ). The feeding method mainly had a greater impact on the morphology and size of the nanoparticles, and had little effect on solution stability, OVA encapsulation efficiency, binding ability with PolyI:C, resistance to nuclease degradation and immune performance. CP-P-O-x prepared by the blend system of COS and PEI will be a potential candidate for tumor treatment.[graphic not available: see fulltext]
