Despite the success of highly active antiretroviral therapy, AIDS still remains as one of the most important world health problems. Toxicity of current available drugs and inevitable emergence of multi-drug resistant strains makes things worse. In the present study a series of novel Biginelli-type pyrimidine compounds were evaluated as potential anti-human(More)
The use of cytokines as adjuvants has been shown to be a promising approach for enhancing DNA vaccine induced-immune responses. In this report, we investigate the administration of cytokines to modulate both humoral and cell-mediated immune responses elicited by an HCV-core plasmid DNA vaccine in Balb/c mice. Our studies indicate that the HCV-core DNA(More)
Genetic adjuvants have potential role in improvement of immune responses against DNA vaccines. GM-CSF as a genetic adjuvant can recruit and augment dendritic cell numbers in the site of immune responses and thereby induce cellular and humoral immune responses. Here we show that co-immunization of a DNA vaccine from HIV-1P24-Nef with GM-CSF in DNA priming(More)
BACKGROUND Using molecular adjuvants offers an attractive strategy to augment DNA vaccine-mediated immune responses. Several studies have revealed that an efficient HCV vaccine model should be able to induce both humoral and cell mediated immune responses targeting the conserved regions of the virus to circumvent the immune escape mutants. The beta(More)
Plasmid DNA vaccination is a promising vaccine platform for prevention and treatment of infectious disease. Enhancement of the DNA vaccine potency by co-inoculation of immunoadjuvant has been shown to be an effective strategy. Modulation of dendritic cells and T-cells locomotion and trafficking to prime an immune response is mediated by distinct chemokines.(More)
Cytokines are mediators for polarization of immune response in vaccines. Studies show that co-immunization of DNA vaccines with granulocyte-macrophage colony-stimulating factor (GM-CSF) can increase immune responses. Here, experimental mice were immunized with HIV-1tat/pol/gag/env DNA vaccine with GM-CSF and boosted with recombinant vaccine. Lymphocyte(More)
Background HTLV-I is causative agent of Acute T-cell Leukemia (ATL) and HTLV-I associated myelopathy/tropical spastic paraparesis (HAM/TSP). To date there isn’t an established treatment available for HTLV-I infection. Type-I IFNs are well known for their antiviral, anti proliferative and immunomodulatory effects. Antiviral mechanism of these IFNs varies(More)
BACKGROUND AIMS Recombinant adenoviruses have tremendous potential in both gene therapy research and therapeutic applications. Mesenchymal stromal cells have a set of several properties that make them ideally suited for both regenerative medicine and gene and drug delivery. A limitation of adenoviral-mediated gene transfer is indeed the poor transduction(More)
