The PAs were based on epitopes gB409-505 and gD301-309, selected from HSV envelope glycoprotein B (gB) and glycoprotein D (gD), that had their N-terminus modified with hydrophobic moieties containing two C18 hydrocarbon chains. Pure and mixed micelles of gB and/or gD peptide epitopes were easily prepared after starting with the synthesis of corresponding PAs by solid phase methods. Structural characterization of the aggregates confirmed that they were sufficiently stable and compatible with in vivo use: critical micelle concentration values around 4.0 · 10-7 mol · Kg-1; hydrodynamic radii (RH) between 50–80 nm, and a zeta potential (ζ) around – 40 mV were found for all aggregates. The in vitro results indicate that both peptide epitopes and micelles, at 10 µM, triggered U937 and RAW 264.7 cells to release appreciable levels of cytokines. In particular, interleukin (IL)-23-, IL-6-, IL-8- or macrophage inflammatory protein (MIP)-2-, and tumor necrosis factor (TNF)-α-release increased considerably when cells were treated with the gB-micelles or gD-micelles compared with the production of the same cytokines when the stimulus was the single gB or gD peptide.Keywords: epitopes, self-adjuvant vaccine, HSVAccardo AVitiello MTesauro DGaldiero MFinamore EMartora FMansi RRinghieri PMorelli GDove Medical PressarticleMedicine (General)R5-920ENInternational Journal of Nanomedicine, Vol 2014, Iss Issue 1, Pp 2137-2148 (2014) |
