[ 1 ] - An LTB-entrapped protein in PLGA nanoparticles preserves against enterotoxin of enterotoxigenic Escherichia coli
Objective(s): Enterotoxigenic Escherichia coli (ETEC) is known as the most common bacterial causes of diarrheal diseases related to morbidity and mortality. Heat-labile enterotoxin (LT) is a part of major virulence factors in ETEC pathogenesis. Antigen entrapment into nanoparticles (NPs) can protect them and enhance their immunogenicity.Materials and Methods: In the present study, recombinant L...
[ 2 ] - بررسی ایمنی‌زایی کاندید واکسن نوترکیب ناحیه اتصالی نوروتوکسین بوتولینوم تیپ E بر پایه کیتوسان به روش مخاطی
زمینه و هدف: سندروم بوتولیسم توسط سروتیپ‌های A تا G نوروتوکسین باکتری‌های جنس کلستریدیوم ایجاد می‌شود. زیرواحد اتصالی نوروتوکسین به‌علت داشتن خاصیت ایمونوژنی، کاندید مناسبی جهت تهیه واکسن است. در این تحقیق ایمنی‌زایی کاندید واکسن نوترکیب ناحیه اتصالی نوروتوکسین بوتولینوم تیپ E بر پایه کیتوسان به روش مخاطی بررسی گردید. روش بررسی: در این مطالعه تجربی، نانوذرات کیتوسان حاوی پروتئین rBoNT/E با روش ...
[ 3 ] - طراحی یک کاندید واکسن نوترکیب حاوی پروتئین هایی از سه باکتری EHEC، ETEC و شیگلا دیسانتری در باکتری E.coli و بررسی ایمنی هومورال آن در موش
Background and purpose: Different genera of enterobacteriaceae have important roles in gastrointestinal diseases such as diarrhea. Among these, Enterotoxigenic E. coli (ETEC), enterohemorrhagic E. coli (EHEC), and Shigella are three main bacteria which are transmitted via contaminated food and water. Vaccination is a good strategy to combat these pathogens. In the present study, a chimeric anti...
[ 4 ] - تهیه نانو واکسن نوترکیب نوروتوکسین بوتولینوم تیپ E بر پایه کیتوسان و مقایسه ایمنی‌زایی آن به دو روش تزریقی و خوراکی در موش سوری
Background and Objectives: Botulism syndrome is caused by one of the seven botulinum neurotoxins. The toxins binding domain have immunogenicity effect and can be used as a recombinant vaccine candidate against botulism disease. Due to the low immunogenicity of recombinant protein , the use of an appropriate vehicle for antigen delivery to target cells is inevitable. The purpose of this study ...
[ 5 ] - Immunogenicity evaluation of rBoNT/E nanovaccine after mucosal administration
Objective(s): The Botulism syndrome is caused by types A to G of botulinum neurotoxins. The binding domains of these neurotoxins are immunogenic and considered as appropriate candidate vaccines. Due to the low immunogenicity of recombinant vaccines, there have been many studies on the use of biocompatible carriers such as chitosan nanoparticles for the delivery of these vaccines. The aim of thi...
[ 6 ] - Expression, purification, and immunization of a chimeric protein containing immunogenic regions of flagellin and intimin proteins against E. coli O157: H7
Introduction: Enterohemorrhagic Escherichia coli (EHEC) and serotype O157: H7 is one of the most important diseases causing diarrhea. Shiga-like toxin secreted by the bacteria destroys epithelial cells and, in acute cases, causes hemolytic uremic syndrome (HUS). Antibiotic therapy is not effective against this pathogen, because it increases the production of Shiga toxin. Designing chimeric immu...
