Venom of the Coral Snake Micrurus clarki: Proteomic Profile, Toxicity, Immunological Cross-Neutralization, and Characterization of a Three-Finger Toxin
(2016)
Micrurus clarki is an uncommon coral snake distributed from the Southeastern Pacific of Costa Rica to Western Colombia, for which no information on its venom could be found in the literature. Using a 'venomics' approach, ...
A myotoxic Lys49 phospholipase A2-homologue is the major component of the venom of Bothrops cotiara from Misiones, Argentina
(2018-04-27)
Bothrops cotiara is a pitviper found in Southeastern Brazil and, scarcely, in the Misiones province of Argentina. In contrast to considerable information available on the venom of the Brazilian snake population, that of ...
Increments in cytokines and matrix metalloproteinases in skeletal muscle after injection of tissue-damaging toxins from the venom of the snake Bothrops asper
(2002)
Envenomations by the snake Bothrops asper are characterized by prominent local tissue damage (i.e. myonecrosis), blistering, hemorrhage and edema. Various phospholipases A2 and metalloproteinases that induce local pathological ...
Comparison of the adjuvant activity of aluminum hydroxide and calcium phosphate on the antibody response towards Bothrops asper snake venom
(2014)
The adjuvanticity of aluminum hydroxide and calcium phosphate on the antibody response in
mice towards the venom of the snake Bothrops asper was studied. It was found that, in vitro,
most of the venom proteins are similarly ...
A new method for the detection of phospholipase A2 variants: identification of isozymes in the venoms of newborn and adult Bothrops asper (terciopelo) snakes
(1988)
A new method for the identification of phospholipase A2 isozymes in snake venoms is described. The technique is based on the separation of the venom components by isoelectric focusing in agarose gels, transfer of the protein ...
A Lys49 phospholipase A2 homologue from Bothrops asper snake venom induces proliferation, apoptosis and necrosis in a lymphoblastoid cell line
(2005-04)
Lys49 phospholipase A2 homologues are abundant in viperid snake venoms. These proteins have substitutions at the calcium-binding loop and catalytic center which render them enzymatically inactive; however, they display a ...
Venom Composition and Diet of the Cantil Agkistrodon bilineatus howardgloydi (Serpentes: Viperidae)
(1999-12)
The southernmost subspecies of the cantil, Agkistrodon bilineatus howardgloydi, occurs in almost all terrestrial habitats of the sector Santa Rosa National Park, in Guanacaste Conservation Area, Costa Rica. We obtained 21 ...
Why myotoxin-containing snake venoms possess powerful nucleotidases?
(2013-01-25)
The venom of the snake Bothrops asper causes muscle necrosis, pain and inflammation. This venom contains myotoxins which cause an increase in intracellular Ca2+ concentration and release of K+ and ATP from myotubes. ATP ...
Catalytically inactive phospholipase A2 homologue binds to vascular endothelial growth factor receptor-2 via C-terminal loop region
(2008)
VEGF (vascular endothelial growth factor) regulates neovascularization
through binding to its receptorKDR(kinase insert domaincontaining
receptor; VEGF receptor-2). We recently identified
a catalytically inactive PLA2 ...
A randomized double-blind clinical trial of two antivenoms in patients bitten by Bothrops atrox in Colombia
(1996-12)
A randomized double-blind clinical trial in 39 patients envenomed by Bothrops atrox in Antioquia and Chocó, Colombia, was performed to compare the efficacy and safety of 2 equine-derived antivenoms prepared at Instituto ...
