Nanovehicles are promising delivery systems for various vaccines. Nevertheless, different biophysicochemical properties of nanoparticles (NPs), dominating their in vitro and in vivo performances for vaccination, remain unclear. We attempted to elucidate the effects of NPs and their pH-sensitivity on in vitro and in vivo efficacy of resulting prophylactic nanovaccines containing a contraceptive ...

Recent advancements in biotechnology have enabled the rapid identification and subsequent expression of pathogenic microbial major antigens that induce protective immune responses. However, subunit vaccines have not been successfully commercialized mainly due to the lack of sufficient levels of neutralizing antibodies (NAs). High levels of NA rely on the efficient recognition and cross-linking ...

The biomimetic nanovaccines not only promoted antigens endocytosis into dendritic cells via receptor-mediated pathways but also induced cross-presentation eliciting CD8+ T-cell responses. CPG-ODN as an adjuvant further enhanced the anti-tumor immune

Development of veterinary subunit vaccines comes with a spectrum challenges, such as the choice adjuvant, antigen delivery vehicle, and optimization dosing strategy. Over years, our laboratory has largely focused on investigating silica vesicles (SVs) for developing effective multiple targets. Rhipicephalus microplus (cattle tick) are known to have high impact cattle health livestock industry i...
