Efficacy of IgG and F(ab′)2 Antivenoms to Neutralize Snake Venom-induced Local Tissue Damage as Assessed by the Proteomic Analysis of Wound Exudate
Proteomic analysis of wound exudates represents a valuable tool to investigate tissue pathology and to assess the therapeutic success of various interventions. In this study, the ability of horse-derived IgG and F(ab0)2 ...
Key events in microvascular damage induced by snake venom hemorrhagic metalloproteinases
Hemorrhage is one of the most significant effects in envenomings induced by viperid snakebites. Damage to the microvasculature, induced by snake venom metalloproteinases (SVMPs), is the main event responsible for this ...
Hemorrhage induced by snake venom metalloproteinases: biochemical and biophysical mechanisms involved in microvessel damage
Zinc-dependent metalloproteinases are responsible for the hemorrhagic activity characteristic of viperid snake venoms. Snake venom metalloproteinases (SVMPs) are classified in various groups (P-I–IV), according to their ...
Isolation and characterization of a myotoxic phospholipase A2 from the venom of the arboreal snake Bothriechis (Bothrops) schlegelii from Costa Rica
A new myotoxic phospholipase A2was isolated from the venom of the arboreal snakeBothriechis schlegelii(formerlyBothrops schlegelii) from Costa Rica, by ion-exchange chromatography on CM-Sephadex.B. schlegeliimyotoxin I is ...
Neutralization of myonecrosis, hemorrhage, and edema induced by Bothrops asper snake venom by homologous and heterologous pre-existing antibodies in mice
The ability of pre-existing antibodies to neutralize locally-acting toxins of Bothrops asper snake venom was investigated. Hemorrhage, myonecrosis, and edema were markedly reduced in actively immunized mice, although ...
Identification of New Snake Venom Metalloproteinase Inhibitors Using Compound Screening and Rational Peptide Design
The majority of snakebite envenomations in Central America are caused by the viperid species Bothrops asper, whose venom contains a high proportion of zinc-dependent metalloproteinases that play a relevant role in the ...
