[ 1 ] - The role of ISCOMATRIX bilayer composition to induce a cell mediated immunity and protection against leishmaniasis in BALB/c mice

Objective(s):Development of new generation of vaccines against leishmaniasis is possible because long-term protection is usually seen after recovery from cutaneous leishmaniasis. ISCOMATRIX is particulate antigen delivery system composed of antigen, cholesterol, phospholipid and saponin. In this study, the role of ISCOMATRIX bilayer composition made by different phase transition temperature (Tc...

[ 2 ] - DDA/TDB liposomes containing soluble Leishmania major antigens induced a mixed Th1/Th2 immune response in BALB/c mice

Objective(s): Leishmaniasis is a complex parasitic disease that represents a major public health problem. Despite numerous attempts over the past decades, yet there is no effective vaccine against human leishmaniasis probably due to the lack of suitable adjuvants. In this study, a first generation liposomal-based Leishmania vaccine was developed using soluble Leishmania major antigens (SLA) and...

[ 3 ] - The role of surface charge of ISCOMATRIX nanoparticles on the type of immune response generated against Leishmaniasis in BALB/c mice

Objective(s): ISCOMATRIX vaccines have now been shown to induce strong antigen-specific cellular or humoral immune responses to a broad range of antigens of viral, bacterial, parasite or tumor. In the present study, we investigated the role of ISCOMATRIX charge in induction of a Th1 type of immune response and protection against Leishmania major infection in BALB/c mice.  Materials and Methods:...

[ 4 ] - Niosome-loaded antifungal drugs as an effective nanocarrier system: A mini review

Skin is an important organ of the body due to offering an accessible and convenient site for drug administration. One of the disadvantages of transdermal drug delivery is the low penetration rate of drugs through the skin. Over the past decades, nanoparticles have been used as drug delivery systems to increase therapeutic effects or reduce toxicity. Encapsulation of drugs in nanoparticulate ves...

[ 5 ] - Immunogenicity and protection effects of cationic liposome containing imiquimod adjuvant on leishmaniasis in BALB/c mice

Objective(s): Protection against leishmaniasis, in the murine model, is dependent on developing a potent CD4+ mediated Th1 type response. Liposomes can be applied as immunoadjuvants to stimulate immune responses to different antigens. In the present study, it was investigated whether DOTAP liposomes having SLA and imiquimod adjuvant, can induce a Th1 response and prote...

[ 6 ] - kDNA and Molecular Typing of Leishmania spp. of Cutaneous Leishmaniasis Patients in Sistan and Baluchestan Province with Low Amount of Parasite

Background: Cutaneous Leishmaniasis, is endemically observed in different parts of Iran in two forms of anthroponotic and zoonotic. The identification of both species and the type of disease are beneficial for treatment and prevention. Microscopic identification of Leishmania species has not provided promising efficacy. The aim of this study was to determine the Le...

[ 7 ] - Liposomes containing the imiquimod adjuvant as a vaccine in the cutaneous leishmaniasis model

Objective(s): Attempts to produce vaccines for leishmaniasis need adjuvants to trigger the kind of immune reaction required for protection. In this study, we examined the properties of the TLR7 agonist imiquimod, a vaccine adjuvant, making use of a live model of infection where the immune reactions could be identified prior to and following the challenge of infection. Materials and Method...
