Role of collagens and perlecan in microvascular stability: exploring the mechanism of capillary vessel damage by snake venom metalloproteinases
(2011-12-08)
Hemorrhage is a clinically important manifestation of viperid snakebite envenomings, and is induced by snake venom metalloproteinases (SVMPs). Hemorrhagic and non-hemorrhagic SVMPs hydrolyze some basement membrane (BM) and ...
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. ...
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 ...
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 ...
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 ...
Muscle Tissue Damage Induced by the Venom of Bothrops asper: Identification of Early and Late Pathological Events through Proteomic Analysis
(2016-04-01)
The time-course of the pathological effects induced by the venom of the snake Bothrops asper in muscle tissue was investigated by a combination of histology, proteomic analysis of exudates collected in the vicinity of ...
Purification and characterization of BaH4, a hemorrhagic metalloproteinase from the venom of the snake Bothrops asper
(2000-01)
A hemorrhagic metalloproteinase, named BaH4, was isolated from the venom of the snake Bothrops asper by a combination of ion-exchange chromatography on DEAE-Sepharose and gel filtration on Sephacryl S-200. BaH4 is a 69 kDa ...
Blister formation and skin damage induced by BaP1, a haemorrhagic metalloproteinase from the venom of the snake Bothrops asper
(1998-08)
Blister formation and skin damage can be induced by BaP1, a haemorrhagic metalloproteinase from the venom of the snake Bothrops asper. Pathological changes in the skin were investigated after intramuscular injections of ...
Characterization of the local tissue damage induced by LHF-II, a metalloproteinase with weak hemorrhagic activity isolated from Lachesis muta muta snake venom
(1999-09)
Local tissue damage induced by LHF-II, a 22-kDa hemorrhagic metalloproteinase from Lachesis muta venom was studied. Intravital microscopy experiments evidenced hemorrhagic events 2 min after LHF-II application onto cremaster ...
Novel insights into capillary vessel basement membrane damage by snake venom hemorrhagic metalloproteinases: A biochemical and immunohistochemical study
(2016-11-15)
The hemorrhagic activity characteristic of viperid snake envenomations is due to the action of venom metalloproteinases (SVMPs) on the capillary vessel basement membrane (BM). This study compared the action of two SVMPs ...
