In silico Analysis of Immunologic Regions of Surface Antigens (Sags) of Toxoplasma gondii

<h2>Background: Surface antigens (SAGs) of Toxoplasma gondii are known candidates for diagnostic tests and vaccines. The present study argues about the main necessary properties for determination and prediction of T-cell agretopes and B-cell epitopes of surface antigens of Toxoplasma gondii.&l...

description <h2>Background: Surface antigens (SAGs) of Toxoplasma gondii are known candidates for diagnostic tests and vaccines. The present study argues about the main necessary properties for determination and prediction of T-cell agretopes and B-cell epitopes of surface antigens of Toxoplasma gondii.</h2><p><strong>M</strong><strong>aterials and Methods: </strong>Primary, secondary and tertiary structures of the proteins were analyzed by different methods. The three-dimensional structures were determined by use of <em>ab initio</em> method for prediction of discontinues epitopes. The agretopes and epitopes were predicted via several various web servers with different methods employed.</p><p><strong>R</strong><strong>es</strong><strong>ults: </strong>The results of <em>in silico</em> analyses showed that the regions 129-GAPAGRNNDGSSAPT-143 for protein p22, 234-SENPWQGNASSD-245 for protein p30 and 348-PGTEGESQAGT-358 for protein p43, have the highest immunogenic potential.</p><p><strong>C</strong><strong>onclusion: </strong>We reached to three antigenic epitopes for cloning and protein expression.
