Identification and Characterization of Eimeria tenella Apical Membrane Antigen-1 (AMA1)
Apical membrane antigen-1 (AMA1) is a micronemal protein of apicomplexan parasites that appears to be essential during the invasion of host cells. In this study, a full-length cDNA of AMA1 was identified from Eimeria tenella (Et) using expressed sequence tag and the rapid amplification of cDNA ends technique. EtAMA1 had an open reading frame of 1608 bp encoding a protein of 535 amino acids. Qua...
متن کاملCharacterization of the antigen SO7 during development of Eimeria tenella.
The developmental expression of the antigen SO7, which has been previously shown to protect chickens against infection by several Eimeria species, was investigated. Using RT-PCR, mRNA for SO7 was found to be restricted primarily to unsporulated oocysts (0 hr). Western blot (WB) analysis with an antibody to recombinant SO7 (rbSO7) revealed expression of the protein from 6 to 72 hr (fully sporula...
متن کاملبررسی گلیکوزیلاسیون آنتی ژن (apical membrane antigen) ama1 در پلاسمودیوم فالسیپاروم
یک فرآیند مهم در چرخه زندگی پلاسمودیوم فالسیپاروم تهاجم به گلبولهای قرمز انسان است. ورود به سلولهای میزبان نیازمند آنتی ژن ama1 می باشد. بدلیل اینکه در یوکاریتوها آنتی بادیهایی که بر علیه این آنتی ژن ایجاد می شود می تواند مانع تهاجم شود بنابراین ama1 یکی از اهداف اولیه در تولید واکسن به شمار می رود. گفته می شود گلیکوزیلاسیون پروتئینهای سطحی در بسیاری از اعمال سلولی نظیر شناسایی سلولها سیگنالینگ...
15 صفحه اولAn Extended Surface Loop on Toxoplasma gondii Apical Membrane Antigen 1 (AMA1) Governs Ligand Binding Selectivity
Apicomplexan parasites are the causative agents of globally prevalent diseases including malaria and toxoplasmosis. These obligate intracellular pathogens have evolved a sophisticated host cell invasion strategy that relies on a parasite-host cell junction anchored by interactions between apical membrane antigens (AMAs) on the parasite surface and rhoptry neck 2 (RON2) proteins discharged from ...
متن کاملAnalysis of Plasmodium vivax Apical Membrane Antigen-1 (PvAMA-1) Haplotypes among Iranian Isolates
Plasmodium vivax apical membrane antigen-1(PvAMA-1) is a surface protein with polymorphic sites. This study was aimed to analyze the polymorphic amino acid residues at PvAMA-1 in different infected age groups. 92 blood samples were collected from south and southeast of Iran. The DNA coding for the domain I (DI), DII, and partial DIII of this antigen was amplified by Nested-PCR, and sequenced. N...
