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...
Processing of Plasmodium falciparum Merozoite Surface Protein MSP1 Activates a Spectrin-Binding Function Enabling Parasite Egress from RBCs
The malaria parasite Plasmodium falciparum replicates within erythrocytes, producing progeny merozoites that are released from infected cells via a poorly understood process called egress. The most abundant merozoite surface protein, MSP1, is synthesized as a large precursor that undergoes proteolytic maturation by the parasite protease SUB1 just prior to egress. The function of MSP1 and its pr...
متن کاملPlasmodium falciparum 19-kilodalton merozoite surface protein 1 (MSP1)-specific antibodies that interfere with parasite growth in vitro can inhibit MSP1 processing, merozoite invasion, and intracellular parasite development.
Merozoite surface protein 1 (MSP1) is a target for malaria vaccine development. Antibodies to the 19-kDa carboxy-terminal region referred to as MSP1(19) inhibit erythrocyte invasion and parasite growth, with some MSP1-specific antibodies shown to inhibit the proteolytic processing of MSP1 that occurs at invasion. We investigated a series of antibodies purified from rabbits immunized with MSP1(1...
متن کاملAntibodies inhibit the protease-mediated processing of a malaria merozoite surface protein
When merozoites of the malaria parasite Plasmodium falciparum are released from infected erythrocytes and invade new red cells, a component of a protein complex derived from the merozoite surface protein 1 (MSP-1) precursor undergoes a single proteolytic cleavage known as secondary processing. This releases the complex from the parasite surface, except for a small membrane-bound fragment consis...
متن کاملMolecular Identification of a Malaria Merozoite Surface Sheddase
Proteolytic shedding of surface proteins during invasion by apicomplexan parasites is a widespread phenomenon, thought to represent a mechanism by which the parasites disengage adhesin-receptor complexes in order to gain entry into their host cell. Erythrocyte invasion by merozoites of the malaria parasite Plasmodium falciparum requires the shedding of ectodomain components of two essential sur...
