چکیده
background : malaria remains a serious public health problem with significant morbidity and mortal-ity. this study was conducted to identify whether ficolin-a could play an active role of against mala-ria infection. methods : the function of ficolin-a was analyzed in mouse model. the open reading frame of fico-lin-a was cloned from the liver of new born c57bl/6 mice by rt-pcr and then inserted into the expression vector of eukaryon to construct pvax1-ficolin-a plasmid. meanwhile, the open reading frame of the 19-kda fragment of merozoite surface protein-1 of plasmodium berghei (msp1 19 ) was cloned and then the expression vector of eukaryon, pvax1- msp1 19 was constructed. both recom-binant vectors were used in the mouse model of infection by plasmodium berghei. results : pvax1-ficolin-a alone could not significantly suppress parasite density and prolong sur-vival time of infection mice; however, when injected pvax1-ficolin-a and pvax1- msp1 19 together, the percent of invasion by plasmodium was decreased (from 43.78% to 22.23% at 10 day after infec-tion, compared to vector ) and the survival time was prolonged significantly in the infection mouse model ( p =0.01). conclusion : ficolin-a can enhance the immunoprotection of msp1 19 , it implies ficolin-a may be used as immunoenhancer in the study of vaccine defending malaria.

بررسی گلیکوزیلاسیون آنتی ژن c-terminal msp1 (c-terminal merozoite surface protein) در پلاسمودیوم فالسیپاروم
مالاریا یکی از بیماری های مهم انگلی در کشورهای گرمسیری دنیا است. پلاسمودیوم فالسیپاروم انگل تک یاخته ای است که تب سه یک بدخیم را ایجاد می کند. آنتی ژن های پلاسمودیوم فالسیپاروم در سطح انگل یا در سطح سلول های آلوده ،کاندیداهای عمده جهت تولید واکسن می باشند، مانند: msp 1 و msp2 . کربوهیدرات های متصل به پروتئین های انگل مالاریا بعنوان اپی توپ های آنتی ژنیک مطرح بوده و بوسیله سیستم ایمنی میزبان تشخ...
analysis of plasmodium vivax merozoite surface protein-1 gene sequences
the emergence of plasmodium vivax in dashte moghan in northwestern iran has become a major concern for iranian's health officials. knowledge of genetic make up of the p. vivax populations in this area would give us an insight into the origin of the prevalent infections and the possible routes they are introduced. this paper reports the analysis of a variable region between the two interspecies ...

We expressed a protein in Saccharomyces cerevisiae in order to evaluate the humoral immune responses to the C-terminal region of the merozoite surface protein 1 of Plasmodium vivax. This protein (Pv200(18)) had a molecular mass of 18 kDa and was reactive with the sera of individuals with patent vivax malaria on immunoblotting analysis. The levels of immunoglobulin M (IgM) and IgG antibodies aga...
