A novel pentameric phospholipase A2 myotoxin (PophPLA2) from the venom of the pit viper Porthidium ophryomegas
(2018-06-07)
The first toxin isolated from the venomous pit viper Porthidiumophryomegas is a basic pentameric phospholipase
A2 (PophPLA2). Elucidation of its amino acid sequence showed that it belongs to the group IIA of secreted ...
Isolation of two basic phospholipases A2 from Bothrops diporus snake venom: comparative characterization and synergism between Asp49 and Lys49 variants
(2019)
Bothrops diporus, previously considered a subspecies of the B. neuwiedi complex, is a medically relevant viperid in
Northeastern Argentina. The venom of this species causes local tissue damage characterized by ...
Snake venomics of Bothriechis nigroviridis reveals extreme variability among palm pitviper venoms: different evolutionary solutions for the same trophic purpose
(2010)
We report the proteomic characterization and biological activities of the venom of the black-speckled palm pitviper, Bothriechis nigroviridis, a neotropical arboreal pitviper from Costa Rica. In marked contrast to other ...
The recovery from the neuroparalysis caused by Micrurus nigrocinctus venom is accelerated by an agonist of the CXCR4 receptor
(2022)
Snake envenoming is a major but neglected human disease in tropical and subtropical regions. Among venomous snakes in the Americas, coral snakes of the genus Micrurus are particularly dangerous because they cause a peripheral ...
Myotoxin-neutralizing peptides
PEPTIDES NEUTRALISANT LES MYOTOXINES
(2018-03-27)
The present invention relates to polypeptides having myotoxin-neutralizing properties and their use for treatment of envenomation. The present invention further relates to methods for neutralizing a venom using the polypeptide ...
Venoms of Micrurus coral snakes: evolutionary trends in compositional patterns emerging from proteomic analyses
(2016-11)
The application of proteomic tools to the study of snake venoms has led to an impressive growth in the
knowledge about their composition (venomics), immunogenicity (antivenomics), and toxicity (toxicovenomics).
About ...
Antivenomics of Atropoides mexicanus and Atropoides picadoi snake venoms: Relationship to the neutralization of toxic and enzymatic activities
(2010-09-30)
Viperid snakes of the genus Atropoides are distributed in Mexico and Central America and, owing to their size and venom yield, are capable of provoking severe envenomings in humans. This study evaluated, using an ‘antivenomics’ ...
Characterization of a novel snake venom component: Kazal-type inhibitor-like protein from the arboreal pitviper Bothriechis schlegelii
(2016-06)
Snake venoms are composed mainly of a mixture of proteins and peptides. Notably, all snake venom toxins have been assigned to a small number of protein families. Proteomic studies on snake venoms have recently identified ...
Comparative biochemical characterization of Viperidae snake venoms from Perú reveals two compositional patterns of phospholipase A2 expression
(2020)
Snake species within the Bothrops complex (sensu lato) are of medical relevance in Latin America, but knowledge on their venom characteristics is limited, or even unavailable, for some taxa. Perú harbors 17 species of pit ...
