Key events in microvascular damage induced by snake venom hemorrhagic metalloproteinases
(2011-08-24)
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 ...
Thrombocytopenia and platelet hypoaggregation induced by Bothrops asper snake venom. Toxins involved and their contribution to metalloproteinase-induced pulmonary hemorrhage.
(2005-07)
Thrombocytopenia and platelet dysfunction occur in patients bitten by Bothrops sp snakes in Latin America. An experimental model was developed in mice to study the effects of B. asper venom in platelet numbers and function. ...
Tissue Localization and Extracellular Matrix Degradation by PI, PII and PIII Snake Venom Metalloproteinases: Clues on the Mechanisms of Venom-Induced Hemorrhage
(2015-04-24)
Snake venom hemorrhagic metalloproteinases (SVMPs) of the PI, PII and PIII classes were
compared in terms of tissue localization and their ability to hydrolyze basement membrane
components in vivo, as well as by a ...
Tissue pathology induced by snake venoms: How to understand a complex pattern of alterations from a systems biology perspective?
(2010-01)
The study of snake venom-induced local tissue pathology has been predominantly based on experimental designs and concepts that view tissue alterations from a dichotomous, homogeneous and reductionist perspective. Experimental ...
Hemorrhage Caused by Snake Venom Metalloproteinases: A Journey of Discovery and Understanding
(2016-03-26)
The historical development of discoveries and conceptual frames for understanding the hemorrhagic activity induced by viperid snake venoms and by hemorrhagic metalloproteinases (SVMPs) present in these venoms is reviewed. ...
Homogenates of skeletal muscle injected with snake venom inhibit myogenic differentiation in cell culture
(2013-02)
Introduction: Viperid snakebite envenomings are characterized by muscle necrosis and a deficient regenerative response. Methods: Homogenates from gastrocnemius muscles of mice injected with the venom of the snake Bothrops ...
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 ...
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 ...
Understanding structural and functional aspects of PII snake venom metalloproteinases: Characterization of BlatH1, a hemorrhagic dimeric enzyme from the venom of Bothriechis lateralis
(2014-06)
A new homodimeric PII metalloproteinase, named BlatH1, was purified from the venom of the Central American arboreal viperid snake Bothriechis lateralis by a combination of anion-exchange chromatography, hydrophobic interaction ...
