Comparative study of the cytolytic activity of snake venoms from African spitting cobras (Naja spp., Elapidae) and its neutralization by a polyspecific antivenom
(2011-11)
Venoms of several Naja species found in Sub-Saharan Africa, and commonly known as "spitting cobras", induce a predominantly cytotoxic pattern of envenomings that may evolve into tissue necrosis and gangrene. Cytotoxic ...
Antivenomics: a proteomics tool for studying the immunoreactivity of antivenoms
(2015-03)
Envenoming following snakebite is largely a neglected threat to public health in tropical and subtropical regions of Africa, Asia, Latin America and Oceania addicting some of the world’s poorest rural communities. An ...
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 ...
Profiling the venom gland transcriptomes of Costa Rican snakes by 454 pyrosequencing
(BMC Genomics, 12:259, 2011, 2011)
Background: A long term research goal of venomics, of applied importance for improving current antivenom
therapy, but also for drug discovery, is to understand the pharmacological potential of venoms. Individually ...
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 of Central American Pitvipers: Clues for Rationalizing the Distinct Envenomation Profiles of Atropoides nummifer and Atropoides picadoi
(2008)
We report the proteomic characterization of the Central American pitvipers Atropoides nummifer and
Atropoides picadoi. The crude venoms were fractionated by reverse-phase high-performance liquid
chromatography (HPLC), ...
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 ...
Venom, venomics, antivenomics
(2009)
Venoms comprise mixtures of peptides and proteins tailored by Natural Selection to act on vital systems
of the prey or victim. Here we review our proteomic protocols for uncoiling the composition,
immunological profile, ...
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’ ...
Novel catalytically-inactive PII metalloproteinases from a viperid snake venom with substitutions in the canonical zinc-binding motif
(2016-10-12)
Snake venom metalloproteinases (SVMPs) play key biological roles in prey immobilization
and digestion. The majority of these activities depend on the hydrolysis of relevant protein substrates
in the tissues. Hereby, we ...
