Pros and cons of different therapeutic antibody formats for recombinant antivenom development
(2018-05)
Antibody technologies are being increasingly applied in the field of toxinology. Fuelled by the many
advances in immunology, synthetic biology, and antibody research, different approaches and antibody
formats are being ...
Chemical modification of histidine and lysine residues of myotoxic phospholipases A2 isolated from Bothrops asper and Bothrops godmani snake venoms: effects on enzymatic and pharmacological properties
(1997-02)
Lysine and histidine residues of two myotoxic phospholipases A2, Bothrops asper myotoxin III and Bothrops godmani myotoxin I, were chemically modified in order to study the effects of these treatments on enzymatic and ...
Backbone Flexibility Controls the Activity and Specificity of a Protein−Protein Interface: Specificity in Snake Venom Metalloproteases
(2010-07-09)
Protein-protein interfaces have crucial functions in many biological processes. The large interaction areas of such interfaces show complex interaction motifs. Even more challenging is the understanding of (multi)specificity ...
Industrial Production and Quality Control of Snake Antivenoms
(2014)
The production of snake antivenoms involves stages such as production of venom, immunization of animals to generate hyperimmune plasma, immunoglobulin purification, viral inactivation (or removal), and stabilization of the ...
High Efficacy of Therapeutic Equine Hyperimmune Antibodies Against SARS-CoV-2 Variants of Concern
(2021)
SARS-CoV-2 variants of concern show reduced neutralization by vaccine-induced and
therapeutic monoclonal antibodies; therefore, treatment alternatives are needed. We
tested therapeutic equine polyclonal antibodies (pAbs) ...
Polyspecific snake antivenom may help in antivenom crisis
(2003-02)
In Africa snakebites cause thousands of deaths annually and much permanent physical disability, but the supply of antivenom, the only specific treatment, is threatened by commercial pressures and privatisation. This has ...
Ability of a polyvalent antivenom to neutralize the venom of Lachesis muta melanocephala, a new Costa Rican subspecies of the bushmaster
(1987)
Several toxic and enzymatic activities of the venom of L. m. melanocephala were studied. This venom has many similarities with that of L. m. stenophrys, although there are quantitative differences in venom activities, as ...
Tissue pathology induced by snake venoms: How to understand a complex pattern of alterations from a systems biology perspective?
(2010-01)
The study of snake venom-induced local tissue pathology has been predominantly based on experimental designs and concepts that view tissue alterations from a dichotomous, homogeneous and reductionist perspective. Experimental ...
12-HETE is a regulator of PGE2 production via COX-2 expression induced by a snake venom group IIA phospholipase A2 in isolated peritoneal macrophages
(2020)
The snake venom myotoxin (MT)-III is a group IIA secreted phospholipase A2 (sPLA2) with pro-inflammatory activities. Previous studies have demonstrated that MT-III has the ability to stimulate macrophages to release ...
Toxicovenomics and antivenom profiling of the Eastern green mamba snake (Dendroaspis angusticeps).
(2016-03-16)
A toxicovenomic study was performed on the venom of the green mamba, Dendroaspis angusticeps. Forty-two different proteins were identified in the venom of D. angusticeps, in addition to the nucleoside adenosine. The most ...
