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 ...
A group IIA-secreted phospholipase A2 from snake venom induces lipid body formation in macrophages: the roles of intracellular phospholipases A2 and distinct signaling pathways
(2011-07)
We investigated the ability of the sPLA(2), known as MT-III, isolated from the viperid snake Bothrops asper, to induce LB formation in macrophages and the major cellular signaling pathways involved in this process. The ...
Intravascular hemolysis induced by the venom of the Eastern coral snake, Micrurus fulvius, in a mouse model: Identification of directly hemolytic phospholipases A2
(Toxicon 90, 2014)
Intravascular hemolysis has been described in envenomings by the Eastern coral snake,
Micrurus fulvius, in dogs. An experimental model of intravascular hemolysis was developed
in mice after intravenous (i.v.) injection ...
Wound exudate as a proteomic window to reveal different mechanisms of tissue damage by snake venom toxins
(2009)
In light of the complexity of wound tissue, proteomic analysis may not clearly reveal the nature of the wound or the processes involved in healing. However, exudate associated with wounds may provide a “window” on cellular ...
The venom of Bothrops asper from Guatemala: toxic activities and neutralization by antivenoms
(2001-02)
Bothrops asper is responsible for approximately half of the snakebite envenomations in Central America. Despite its medical relevance, only the venom of Costa Rican populations of this species has been studied to some ...
Systemic and local myotoxicity induced by snake venom group II phospholipases A2: Comparison between crotoxin, crotoxin B and a Lys49 PLA2 homologue
(2008-01)
The patterns of myotoxicity induced in mice by crotoxin, crotoxin B and a Lys49 phospholipase A2 (PLA2) homologue were compared. Lys49 PLA2-induced local myotoxicity is reflected by creatine kinase (CK) loss in injected ...
Neutralization, by a monospecific Bothrops lanceolatus antivenom, of toxic activities induced by homologous and heterologous Bothı́rops snake venoms
(1999-03)
A monospecific Bothrops lanceolatus antivenom, currently used in Martinique, was tested for its efficacy in the neutralization of several toxic and enzymatic activities of the venoms of B. lanceolatus, B. atrox and B. ...
Snake venomics and antivenomics: Proteomic tools in the design and control of antivenoms for the treatment of snakebite envenoming
(2009-03-06)
Snakebite envenoming represents a neglected tropical disease that has a heavy public health impact, particularly in Asia, Africa and Latin America. A global initiative, aimed at increasing antivenom production and ...
Evaluación de la capacidad de cuatro antivenenos comerciales para neutralizar el veneno de la serpiente Bothrops asper (terciopelo) de Costa Rica
(1995-09)
We studied the ability of four commercially available antivenoms to neutralize several toxic and enzymatic activities of Bothrops asper (terciopelo) venom from Costa Rica. Experiments with preincubation of venom and antivenom ...
