Fibronectin EDA and CpG synergize to enhance antigen-specific Th1 and cytotoxic responses

Jeffrey Alan Hubbell, Melody Swartz, Alexandre de Titta, Ziad Julier, Eleonora Simeoni, Alizée Jéléna Grimm

Subunit vaccines, employing purified protein antigens rather than intact pathogens, require the addition of adjuvants for enhanced immunogenicity with a correct balance between strong activation of the immune system and low toxicity. Here we show that the ...

TLR-3 stimulation improves anti-tumor immunity elicited by dendritic cell exosome-based vaccines in a murine model of melanoma

Jeffrey Alan Hubbell, Eleonora Simeoni, Martina Damo, David Scott Wilson

Dendritic cell (DC)-derived exosomes (Dexo) contain the machinery necessary to activate potent antigen-specific immune responses. As promising cell-free immunogens, Dexo have been tested in previous clinical trials for cancer vaccine immunotherapy, yet res ...

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 ...

Nanoparticle conjugation and pulmonary delivery enhance the protective efficacy of Ag85B and CpG against tuberculosis

Jeffrey Alan Hubbell, Melody Swartz, Cyntia De Piano, Alexandre de Titta, Marie Ballester, Miriella Carmela Pasquier, Eleonora Simeoni, John McKinney, Neeraj Dhar

Vaccines that drive robust T-cell immunity against Mycobacterium tuberculosis (Mtb) are needed both for prophylactic and therapeutic purposes. We have recently developed a synthetic vaccine delivery platform with Pluronic-stabilized polypropylene sulfide n ...

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 ...

PEG-b-PPS-b-PEI micelles and PEG-b-PPS/PEG-b-PPS-b-PEI mixed micelles as non-viral vectors for plasmid DNA: Tumor immunotoxicity in B16F10 melanoma

Jeffrey Alan Hubbell, Melody Swartz, Eleonora Simeoni, Susan Thomas

Cationic micelles formed from poly(ethylene glycol)-bl-poly(propylene sulfide)-bl-poly(ethylene imine) (PEG-b-PPS-b-PEI) and from mixtures of poly(ethylene glycol)-bl-poly(propylene sulfide) (PEG-b-PPS) with PEG-b-PPS-b-PEI were explored as non-viral vecto ...

Carbon Monoxide-Releasing Micelles for Immunotherapy

Jutta Christine Wandrey, Jeffrey Alan Hubbell, Eleonora Simeoni, Urara Hasegawa

With the discovery of important biological roles of carbon monoxide (CO), the use of this gas as a therapeutic agent has attracted attention. However, the medical application of this gas has been hampered by the complexity of the administration method. To ...

Nanoparticles for immunotherapy

Jeffrey Alan Hubbell, Melody Swartz, Conlin O'Neil, Sai Reddy, Eleonora Simeoni

Nanoparticles that activate complement in the absence of biological molecules are described. The nanoparticles are shown to specifically target antigen presenting cells in specifically in lymph nodes, without the use of a biological molecule for targeting. ...
