Nanoparticles (NPs) are effective and safe adjuvants for antigen delivery in modern vaccinology. Biodegradable nanomaterials with suitable properties are frequently applied for conjugation or loading with antigens; they protect the antigens from degradation in vivo. NPs are applied as effective delivery system to facilitate antigen uptake by antigen presenting cells (APCs) and especially dendri...
Chronic hepatitis B infection (CHB) is characterized by sub-optimal T cell responses to viral antigens. A therapeutic vaccine capable of restoring these immune responses could potentially improve HBsAg seroconversion rates in the setting of direct acting antiviral therapies. A yeast-based immunotherapy (Tarmogen) platform was used to make a vaccine candidate expressing hepatitis B virus (HBV) X...
Purpose:Wequestionedwhether the vaccine adjuvant combinationof TLR-7 ligand agonist, imiquimod, with granulocyte macrophage colony-stimulating factor (GM-CSF) would result in enhanced dendritic cell recruitment and activationwith increased antigen-specific immunity as comparedwith either adjuvant used
Several modes of vaccine delivery have been developed in the last 25 years, which induce strong immune responses in pre-clinical models and in human clinical trials. Some modes of delivery include, adjuvants (aluminum hydroxide, Ribi formulation, QS21), liposomes, nanoparticles, virus like particles, immunostimulatory complexes (ISCOMs), dendrimers, viral vectors, DNA delivery via gene gun, ele...
PURPOSE We questioned whether the vaccine adjuvant combination of TLR-7 ligand agonist, imiquimod, with granulocyte macrophage colony-stimulating factor (GM-CSF) would result in enhanced dendritic cell recruitment and activation with increased antigen-specific immunity as compared with either adjuvant used alone. EXPERIMENTAL DESIGN The adjuvant effects of GM-CSF and imiquimod were studied in...
Microneedle vaccines mimic several aspects of cutaneous pathogen invasion by targeting antigen to skin-resident dendritic cells and triggering local inflammatory responses in the skin, which are correlated with enhanced immune responses. Here, we tested whether control over vaccine delivery kinetics can enhance immunity through further mimicry of kinetic profiles present during natural acute in...
The goal of cancer vaccines is to induce antitumor immunity that ultimately will reduce tumor burden in tumor environment. Several strategies involving dendritic cells- (DCs)- based vaccine incorporating different tumor-associated antigens to induce antitumor immune responses against tumors have been tested in clinical trials worldwide. Although DCs-based vaccine such as fusions of whole tumor ...
during antigen capture and processing, mature dendritic cells (dc) express large amounts of peptide-mhc complexes and accessory molecules on their surface. we investigated the role of ifn-β in induction hla-g expression on the monocyte derived dc and cytokine profile in diabetes type 1. we accomplished secretary pattern and total cytokine production of the th1 cytokine (il-2, γifn) and th2 cyto...
BACKGROUND Harnessing the immune response in treating breast cancer would potentially offer a less toxic, more targeted approach to eradicating residual disease. Breast cancer vaccines are being developed to effectively train cytotoxic T cells to recognize and kill transformed cells while sparing normal ones. However, achieving this goal has been problematic due to the ability of established ca...
Immunization of cancer patients is most effective in tumor-free conditions or in the presence of minimal residual disease. In the attempt to develop new strategies able to control tumor recurrence while allowing the development of protective immunity, we have investigated the immunogenic potential of two distinct vaccine formulations when provided alone or upon single and repeated treatment wit...
