Construction and physiochemical characterisation of a multi-composite, potential oral vaccine delivery system (VDS)
International journal of pharmaceutics
Abstract: An increasing human population requires a secure food supply and a cost effective, oral vaccine delivery system for livestock would help facilitate this end. Recombinant antigen adsorbed onto silica beads and coated with myristic acid, was released (∼15% (w/v)) over 24 h at pH 8.8. At pH 2, the myristic acid acted as an enteric coating, protecting the antigen from a variety of proteases. The antigen adsorbed onto silica particles, coated in myristic acid had a conserved secondary…
Abstract: An increasing human population requires a secure food supply and a cost effective, oral vaccine delivery system for livestock would help facilitate this end. Recombinant antigen adsorbed onto silica beads and coated with myristic acid, was released (∼15% (w/v)) over 24 h at pH 8.8. At pH 2, the myristic acid acted as an enteric coating, protecting the antigen from a variety of proteases. The antigen adsorbed onto silica particles, coated in myristic acid had a conserved secondary structure (measured by circular dichroism (CD) spectroscopy) following its pH-triggered release. Small angle neutron scattering (SANS) was used to measure the thickness of the adsorbed antigen, finding that its adsorbed conformation was slightly greater than its solution radius of gyration, i.e. 120–160 Å. The addition of myristic acid led to a further increase in particle size, with scattering data consistent with an acid thickness slightly greater than a monolayer of fully extended alkyl chains and a degree of hydration of around 50%. Whilst adsorbed onto the silica and coated in myristic acid, the protein was stable over 14 days at 42 °C, indicating a reduced need for cold chain storage. These data indicate that further investigation is warranted into the development of this technology.

Antisense Oligonucleotide Compositions
Issued GB GB201311057D0
The present invention relates to antisense oligonucleotide (ASO) compositions and particularly to compositions and methods for the cytosolic delivery of antisense oligonucleotides (ASOs). Hybrid ASOs, part single-stranded and part double-stranded, are provided, hybridising to form a double-stranded region that can non-covalently bond to nucleic-acid-binding protein regions. In this way, ASO::protein complexes may be produced that facilitate delivery of antisense DNA into target cells. Such…
