Down-Regulation of T Cell Function by Heat Shock-Induced Excretory Factor of Leishmania Major

Background: Despite demonstration of molecular and biochemical changes induced by heat shock on Leishmania, the immunological importance of such changes has not been elucidated.  Objective: Studying the effect of two excretory factors prepared under heat shock and ambient temperature from Leishmania major on Balb/c splenocytes function.  Methods: The parasites were cultured at 25°C and then sub...

Dengue virus type-3 envelope protein domain III; expression and immunogenicity

Objective(s): Production of a recombinant and immunogenic antigen using dengue virus type-3 envelope protein is a key point in dengue vaccine development and diagnostic researches. The goals of this study were providing a recombinant protein from dengue virus type-3 envelope protein and evaluation of its immunogenicity in mice. Materials and Methods: Multiple amino acid sequences of different i...

Interferon Gamma Unresponsiveness Due to Down-Regulation of IFN-γR Expression in Experimental Cutaneous Leishmaniasis

It is now well documented that interferon gamma (IFN-γ) is the indispensable cytokine for inducing protective immunity against experimental and human cutaneous leishmaniaisis. The importance of IFN-γ receptor (IFN-γR) has also been studied. In the present study, we made attempts to find out whether L. major infection is able to alter the expression of IFN-γR in vivo. In addition, we studied the...

IFN-gamma up-regulates IL-18 gene expression via IFN consensus sequence-binding protein and activator protein-1 elements in macrophages.

Constitutive IL-18 expression is detected from many different cells, including macrophages, keratinocytes, and osteoblasts. It has been known that IL-18 gene expression is regulated by two different promoters (p1 promoter and p2 promoter). When RAW 264.7 macrophages were treated with IFN-gamma, IL-18 gene expression was increased in a dose- and time-dependent manner. IFN-gamma activated the ind...
