Engineering Venom’s Toxin-Neutralizing Antibody Fragments and Its Therapeutic Potential
Serum therapy remains the only specific treatment against envenoming, but anti-venoms are still prepared by fragmentation of polyclonal antibodies isolated from hyper-immunized horse serum. Most of these anti-venoms are considered to be efficient, but their production is tedious, and their use may be associated with adverse effects. Recombinant antibodies and smaller functional units are now em...
متن کاملRecombinant Clostridium difficile Toxin Fragments as Carrier Protein for PSII Surface Polysaccharide Preserve Their Neutralizing Activity
Clostridium difficile is a Gram-positive bacterium and is the most commonly diagnosed cause of hospital-associated and antimicrobial-associated diarrhea. Despite the emergence of epidemic C. difficile strains having led to an increase in the incidence of the disease, a vaccine against this pathogen is not currently available. C. difficile strains produce two main toxins (TcdA and TcdB) and expr...
متن کاملToxin-neutralizing effect of antibody against subtilisin-digested tetanus toxin.
A form of systemic tetanus with atypical symptoms was observed in mice injected in the left thigh with a mixture of tetanus toxin and antibody produced in guinea pigs against a fragment of toxin obtained from a subtilisin digest of the crystallized toxin. The mice did not show typical symptoms of the local tetanus such as convulsions or spastic paralysis of the injected limb.
متن کاملRecombinant Shiga toxin B subunit can induce neutralizing immunoglobulin Y antibody.
Previously, we have shown that chickens immunized with Shiga toxin (Stx) produce Stx-neutralizing egg yolk immunoglobulin Y (IgY) antibody. The anti-Stx-1 IgY and anti-Stx-2 IgY exert their neutralizing activity through their antibody activity against the B subunit of the toxin but not the A subunit. In the present study, chickens were immunized with recombinant Stx-1 B subunit (rStx-1B) and re...
متن کاملRecombinant Antibody Fragments for Neurodegenerative Diseases
BACKGROUND Recombinant antibody fragments are promising alternatives to full-length immunoglobulins and offer important advantages compared with conventional monoclonal antibodies: extreme specificity, higher affinity, superior stability and solubility, reduced immunogenicity as well as easy and inexpensive large-scale production. OBJECTIVE In this article we will review and discuss recombina...
