Evaluation of the Immune Response in Mice Infected

Evaluation of Th1 and TH2 Cytokine Network in Aspergilus Infected Tumor Bearing Mice

Background & Objective: Invasive Aspergillosis is a fatal infection in immunocompromised patients. The aim of this study was to evaluate the interaction of infectious with Aspergillus and tumor on immune response and cytokine network in Aspergillus infected tumor-bearing mice. Materials and Methods: Mice were implanted by sterile pieces of mouse mammary tumor and then infected by Aspergillus co...

The Assessment of Cytokine and Antibody Responses to Recombinant 31kDa Brucella Cell-Surface Protein in Brucella Abortus Infected Mouse Model

Background & Objective: One of the most common diseases between zoonosis - especially in developing countries – is brucellosis. Identification of Brucella cell antigen combinations in terms of the amount and type of immune response in infected hosts, are important in vaccine design. 31kDa Brucella cell surface protein (BCSP31) is shared among all Brucellae. We aimed to define specific immune r...

Evaluation of Humoral Immune Response to Foot-and-Mouth Disease Vaccination in Experimentally Infected Guinea Pigs with Trypanosoma evansi

Western Blot Analysis of Sera from Leishmania major-Infected BALB/c and C57BL/6 Mice

In Leishmania (L.) major-infected BALB/c mice Th2-type cells results in disease progression, whereas C57BL/6-infected mice mount a Th1-type response, which leads to control of the infection. Th2 response correlates with IgG1 whereas, Th1 response supports switching to IgG2a subclasses. Since IgG isotype-dominated response depends on different CD4 + T cell subsets, we studied the antigenic profi...

Evaluation of immune response against autoclaved Leishmania major incorporated into positively charged liposomes in Balb/c mice

Background and aim: Efficacy of vaccines is mainly depending on the type of adjuvant used. Efficacy trials of first generation vaccine against leishmaniasis showed a limited efficacy due to lack of an appropriate adjuvant. The objective of this study was to investigate whether positively charged liposomes containing ALM could induce Th1 type immune response in susceptible Balb/c mice.Mate...

Protective Role of Antigens from Peritoneal Exudates of Infected Mice against Toxoplasmosis

Background: Toxoplasma gondii is an obligate intracellular parasite that infects all mammalian cells. Several antigens such as excreted/secreted antigens have been identified as a potential vaccine candidate. Objective: To determine how excreted/secreted antigens from peritoneal exudates of infected mice (mESA) stimulate cell-mediated immune responses and induce protective immunity against toxo...
