Cytotoxicity of snake venom Lys49 PLA2-like myotoxin on rat cardiomyocytes ex vivo does not involve a direct action on the contractile apparatus
(2021-09)
Viperid snake venoms contain a unique family of cytotoxic proteins, the Lys49 PLA2 homologs, which are devoid of enzymatic activity but disrupt the integrity of cell membranes. They are known to induce skeletal muscle ...
Venomic and antivenomic analyses of the Central American coral snake, Micrurus nigrocinctus (Elapidae)
(2011-01-31)
The proteome of the venom of Micrurus nigrocinctus (Central American coral snake) was analyzed by a “venomics” approach. Nearly 50 venom peaks were resolved by RP-HPLC, revealing a complex protein composition. Comparative ...
Snake Venomics and Antivenomics of the Arboreal Neotropical Pitvipers Bothriechis lateralis and Bothriechis schlegelii
(2008-04-30)
We report the comparative proteomic characterization of the venoms of two related neotropical arboreal pitvipers from Costa Rica of the genus Bothriechis, B. lateralis (side-striped palm pit viper) and B. schlegelii (eyelash ...
First look into the venom of Roatan Island´s critically endangered coral snake Micrurus ruatanus: proteomic characterization, toxicity, immunorecognition and neutralization by an antivenom
(2019)
A proteomic and toxicological study of the venom from one specimen of Micrurus ruatanus, a critically endangered
coral snake species endemic to Roatan Island, Honduras, was carried out. Immunorecognition and
neutralization ...
Envenomations by Bothrops and Crotalus Snakes Induce the Release of Mitochondrial Alarmins
(PLoS Negl Trop Dis 6(2): e1526, 2012-02-21)
Skeletal muscle necrosis is a common manifestation of viperid snakebite envenomations. Venoms from snakes of the genus Bothrops, such as that of B. asper, induce muscle tissue damage at the site of venom injection, provoking ...
Integrative characterization of the venom of the coral snake Micrurus dumerilii (Elapidae) from Colombia: proteome, toxicity, and cross-neutralization by antivenom
(2016-03)
In Colombia, nearly 2.8% of the 4200 snakebite accidents recorded annually are inflicted by coral snakes (genus
Micrurus). Micrurus dumerilii has a broad distribution in this country, especially in densely populated ...
Proteomic profiling, functional characterization, and immunoneutralization of the venom of Porthidium porrasi, a pitviper endemic to Costa Rica
(2019)
The genus Porthidium includes nine pitviper species inhabiting Mexico, Central America, and northern South
America. Porthidium porrasi is a species endemic to the Southwest of Costa Rica, for which no information on ...
Structural basis for phospholipase A2-like toxin inhibition by the synthetic compound Varespladib (LY315920)
(2019)
The World Health Organization recently listed snakebite envenoming as a Neglected Tropical Disease,
proposing strategies to significantly reduce the global burden of this complex pathology by 2030. In
this context, ...
Intravascular hemolysis induced by phospholipases A2 from the venom of the Eastern coral snake, Micrurus fulvius: functional profile of hemolytic and non-hemolytic isoforms
(2018-04)
A unique feature of the venom of Micrurus fulvius (Eastern coral snake) is its ability to induce severe intravascular
hemolysis in particular species, such as dogs or mice. This effect was previously shown to be induced ...
Amino acid sequence and biological characterization of BlatPLA2, a non-toxic acidic phospholipase A2 from the venom of the arboreal snake Bothriechis lateralis from Costa Rica
(2013-10)
Bothriechis is considered a monophyletic, basal genus of arboreal Neotropical pitvipers
distributed across Middle America. The four species found in Costa Rica (B. lateralis, B.
schlegeli, B. nigroviridis, B. supraciliaris) ...
