[h=1]Chimeric virus-like Particles Made Using GAG and M1 Capsid Proteins Providing Dual Drug Delivery and Vaccination Platform.[/h] Deo VK, Kato T, Park EY.
[h=3]Abstract[/h] Nanobiomaterials such as enveloped virus-like particles with specificity can serve a dual function of vaccination and drug delivery system. Here, we expressed colon carcinoma cell-targeting chimeric virus-like particles (VLPs) made using two capsid proteins, gag and M1 from influenza virus A/swine flu/Iowa/15/30/H1N1 in silkworms. These chimeric VLPs displayed a glycosylphosphatidylinositol-anchored single-chain variable fragment region targeting colon carcinoma cells, and their shape was smooth with an average particle size of 21 nm in diameter. Large unilamellar vesicles made from DOPC
OPA (2:1) containing calcein-AM (10 μM) or doxorubicin (13.7 nM) were used to package chimeric VLPs. VLPs showed high specificity in targeting cancer cells and delivered the dye and drug to cells successfully. Chimeric VLPs were injected into BALB/c mice and the serum raised showed specificity for M1 protein as a model.
