Identification of the SV2 protein receptor-binding site of botulinum neurotoxin type E.

Immunogenic and Protective Potentials of Recombinant Receptor Binding Domain and a C-Terminal Fragment of Clostridium botulinum Neurotoxin Type E

Clostridium Botulinum Type E neurotoxin heavy chain consists of two domains: the translocation domain asthe N-terminal half and the binding domain as the Cterminal half (Hc). One effective way to neutralize botulinum neurotoxin is to inhibit binding of this toxin to neuromuscular synapses with antibodies against binding domain. Two synthetic genes, coding for Hc (the full length binding d...

Comparative Study of Immunological and Structural Properties of Two Recombinant Vaccine Candidates against Botulinum Neurotoxin Type E

Background: Recently, botulinum neurotoxin (BoNT)-derived recombinant proteins have been suggested as potential botulism vaccines. Here, with concentrating on BoNT type E (BoNT/E), we studied two of these binding domain-based recombinant proteins: a multivalent chimer protein, which is composed of BoNT serotypes A, B and E binding subdomains, and a monovalent recombinant protein, which contains...

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 ...

Cloning, Expression and Purification of Clostridium botulinum Neurotoxin Type E Binding Domain

Botulinum Neurotoxin D Uses Synaptic Vesicle Protein SV2 and Gangliosides as Receptors

Botulinum neurotoxins (BoNTs) include seven bacterial toxins (BoNT/A-G) that target presynaptic terminals and act as proteases cleaving proteins required for synaptic vesicle exocytosis. Here we identified synaptic vesicle protein SV2 as the protein receptor for BoNT/D. BoNT/D enters cultured hippocampal neurons via synaptic vesicle recycling and can bind SV2 in brain detergent extracts. BoNT/D...
