A high-throughput nanoimmunoassay chip applied to large-scale vaccine adjuvant screening

Jeffrey Alan Hubbell, Sebastian Maerkl, Armando Stano, Jose Luis Garcia Cordero

Large-scale experimentation is becoming instrumental in enabling new discoveries in systems biology and personalized medicine. We developed a multiplexed high-throughput nanoimmunoassay chip capable of quantifying four biomarkers in 384 5 nL samples, for a ...

Tunable T cell immunity towards a protein antigen using polymersomes vs. solid-core nanoparticles

Jeffrey Alan Hubbell, Melody Swartz, Armando Stano, Karen Dane

Using poly(propylene sulfide) (PPS) and poly(ethylene glycol) (PEG) as components of a nanocarrier platform, we sought to compare immune responses induced by PPS-bl-PEG polymersomes (PSs; watery-core structures, with antigen incorporated within the PSs) an ...

Improving Immunogenicity of Subunit Vaccines Using Nanocarrier Systems

Armando Stano

New generation vaccines, which are subunit vaccines, have considerably improved safety profiles, but are often poorly immunogenic, especially when administered through mucosal routes. Also, the diversity of the mechanisms of action of infectious pathogens ...

Nanoparticle size influences the magnitude and quality of mucosal immune responses after intranasal immunization

Jeffrey Alan Hubbell, Melody Swartz, Eleonora Simeoni, Armando Stano

Background: The development of nanoparticulate antigen-delivery systems is an important emerging area of vaccinology, being sought to amplify immune responses to recombinant antigens that are poorly immunogenic. Nanoparticle size may play an important role ...

Dendritic cell activation and T cell priming with adjuvant- and antigen-loaded oxidation-sensitive polymersomes

Jeffrey Alan Hubbell, Melody Swartz, Armando Stano

While current subunit vaccines successfully induce humoral immune responses, a need exists for vaccine strategies to elicit strong cell-mediated immunity to address diseases such as cancer and chronic viral infection. Polymersomes are stable vesicles compo ...

Nanoparticle conjugation of antigen enhances cytotoxic T-cell responses in pulmonary vaccination

Jeffrey Alan Hubbell, Melody Swartz, Marie Ballester, Armando Stano, Karen Dane, Benjamin John Marsland

The ability of vaccines to induce memory cytotoxic T-cell responses in the lung is crucial in stemming and treating pulmonary diseases caused by viruses and bacteria. However, most approaches to subunit vaccines produce primarily humoral and only to a less ...

PPS nanoparticles as versatile delivery system to induce systemic and broad mucosal immunity after intranasal administration

Mikaël Martino, Jeffrey Alan Hubbell, Melody Swartz, Eleonora Simeoni, Armando Stano

Degradable polymer nanoparticles (NPs, 50nm) based on polypropylene sulfide (PPS) were conjugated to thiolated antigen and adjuvant proteins by reversible disulfide bonds and evaluated in mucosal vaccination. Ovalbumin was used as a model antigen, and anti ...
