background: leishmaniasis is a worldwide disease prevalent in tropical and sub tropical coun­tries. many attempts have been made and different strategies have been approached to develop a potent vaccine against leishmania . dna immunisation is a method, which is shown to be effec­tive in leishmania vaccination. leishmania soluble antigen (sla) has also recently been used leishmania vaccination....

this study was performed in order to define the cellular immune response of 12 recovered cutaneous leishmaniasis subjects to different soluble antigens of the amastigote form of leishmania major. a soluble leishmanial antigen preparation (sla) derived from highly-purified amastigotes from infected nude mice was fractionated by mono q column using fast protein liquid chromatography (fplc) system...

Background: Macrophages activation is the important anti-leishmania immune response. Different signals could affect macrophages development and functional activation. Objectives: In the present study, we compared the effect of Leishmania Soluble Antigen (LSA)and Lipopolysaccharide (LPS) on peritoneal macrophage responses. Appropriate activation of macrophages depends on thesignals they receive ...

Vi antibody response of rabbits varied depending on whether Vi antigen was administered in particulate or soluble state. Vi antigen in particulate form induced hemagglutinins, bacterial agglutinins, and passive cutaneous anaphylaxis (PCA) antibodies, whereas soluble Vi antigen induced only hemagglutinins. Guinea pigs passively sensitized with antisera against particulate Vi antigen gave PCA rea...
