Comparison between IgG and F(ab′)2 polyvalent antivenoms: neutralization of systemic effects induced by Bothrops asper venom in mice, extravasation to muscle tissue, and potential for induction of adverse reactions
(2001-06)
Whole IgG and F(ab′)2 equine-derived polyvalent (Crotalinae) antivenoms, prepared from the same batch of hyperimmune plasma, were compared in terms of neutralization of the lethal and defibrinating activities induced by ...
Snake venomics of Micrurus alleni and Micrurus mosquitensis from the Caribbean region of Costa Rica reveals two divergent compositional patterns in New World elapids
(2015-12-01)
Protein composition, toxicity, and neutralization of the venoms of Micrurus alleni and Micrurus mosquitensis, two sympatric monadal coral snakes found in humid environments of the Caribbean region of Costa Rica, were ...
Snake venomics and antivenomics of Bothrops atrox venoms from Colombia and the Amazon regions of Brazil, Perú and Ecuador suggest the occurrence of geographic variation of venom phenotype by a trend towards paedomorphism
(2009-11-02)
The venom proteomes of Bothrops atrox from Colombia, Brazil, Ecuador, and Perú were characterized using venomic and antivenomic strategies. Our results evidence the existence of two geographically differentiated venom ...
Intraspecies variation in the venom of the rattlesnake Crotalus simus from Mexico: Different expression of crotoxin results in highly variable toxicity in the venoms of three subspecies
(2013-07)
The composition and toxicological profile of the venom of the rattlesnake Crotalus simus in
Mexico was analyzed at the subspecies and individual levels. Venoms of the subspecies C. s.
simus, C. s. culminatus and C. s. ...
Comparison of venom composition and biological activities of the subspecies Crotalus lepidus lepidus, Crotalus lepidus klauberi and Crotalus lepidus morulus from Mexico
(2013-08-01)
The rock rattlesnakes Crotalus lepidus comprise a group (lepidus, klauberi, morulus and
maculosus) of poorly known mountain cold-tolerant snakes in Mexico. In particular, Crotalus
lepidus morulus is a snake endemic of ...
Anti-human erythrocyte antibodies in horse-derived antivenoms used in the treatment of snakebite envenomations
(2007-03)
This work examined the presence of antibodies reacting with human erythrocytes in horse-derived antivenoms used in the treatment of snakebite envenomations, and assessed the efficacy of various fractionation protocols in ...
Critical role of TLR2 and MyD88 for functional response of macrophages to a group IIA-Secreted phospholipase A2 from snake venom
(PLoS One 9(4):e93741, 2014-04-09)
The snake venom MT-III is a group IIA secreted phospholipase A2 (sPLA2) enzyme with functional and structural similarities with mammalian pro-inflammatory sPLA2s of the same group. Previously, we demonstrated that MT-III ...
Pharmacokinetics of whole IgG equine antivenom: comparison between normal and envenomed rabbits
(2006-09-01)
Pharmacokinetics of antivenoms has been mainly studied in normal animals, whereas very little is known on pharmacokinetics in envenomed animals. The aim of this study was to compare pharmacokinetic parameters of whole IgG ...
A Lys49 Phospholipase A2, Isolated from Bothrops asper Snake Venom, Induces Lipid Droplet Formation in Macrophages Which Depends on Distinct Signaling Pathways and the C-Terminal Region
(2013)
MT-II, a Lys49PLA2 homologue devoid of catalytic activity from B. asper venom, stimulates inflammatory events in macrophages. We investigated the ability of MT-II to induce formation of lipid droplets (LDs), key elements ...
Structural and functional properties of BaTX, a new Lys49 phospholipase A2 homologue isolated from the venom of the snake Bothrops alternatus
(2007-04)
BaTX PLA2, a K49 phospholipase A2 homologue was purified from Bothrops alternatus venom after two chromatographic steps, molecular exclusion on Superdex 75 and reverse phase HPLC on μ-Bondapack C-18. A molecular mass of ...
