عنوان انگلیسی EVALUATION OF CELLULAR IMMUNE RESPONSES TO AMASTIGOTE SOLUBLE Leishmania major ANTIGENS IN RECOV ERED CASES OF CUTANEOUS LEISHMANIASIS
چکیده انگلیسی مقاله 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. Three different fractions were obtained. The lymphoproliferative response, interferon•gamma (IFN.'Y) and interleukin•4 (JL•4) to amastigote SLA and its three subfractions were measured. The highest proliferative response and specific IFN.'Y production without synthesis of fL•4, was induced by the fITst fraction of amastigote SLA. These results showed that the individuals who had recovered from cutaneous leishmaniasis had expanded memory T- cell clones recognizing different antigens in the first fraction of amastigote SLA. The main and most important point of this study was the identification of one fraction of an amastigote antigen which preferentially reacted with cells from recovered human cutaneous leishmaniasis cases.
