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 ...
12-HETE is a regulator of PGE2 production via COX-2 expression induced by a snake venom group IIA phospholipase A2 in isolated peritoneal macrophages
(2020)
The snake venom myotoxin (MT)-III is a group IIA secreted phospholipase A2 (sPLA2) with pro-inflammatory activities. Previous studies have demonstrated that MT-III has the ability to stimulate macrophages to release ...
Toxicovenomics and antivenom profiling of the Eastern green mamba snake (Dendroaspis angusticeps).
(2016-03-16)
A toxicovenomic study was performed on the venom of the green mamba, Dendroaspis angusticeps. Forty-two different proteins were identified in the venom of D. angusticeps, in addition to the nucleoside adenosine. The most ...
Evaluation of antivenoms in the neutralization of hyperalgesia and edema induced by Bothrops jararaca and Bothrops asper snake venoms
(2002-10)
Neutralization of hyperalgesia induced by Bothrops jararaca and B. asper venoms was studied in rats using bothropic antivenom produced at Instituto Butantan (AVIB, 1 ml neutralizes 5 mg B. jararaca venom) and polyvalent ...
Venomous snakes of Costa Rica: biological and medical implications of their venom proteomic profiles analyzed through the strategy of snake venomics
(Journal of Proteomics XX (2014) XXX – XXX, Available online 24 February 2014, 2014-02-24)
In spite of its small territory of ~50,000 km2, Costa Rica harbors a remarkably rich biodiversity. Its herpetofauna includes 138 species of snakes, of which sixteen pit vipers (family Viperidae, subfamily Crotalinae), five ...
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. ...
Neurotoxicity and other pharmacological activities of the snake venom phospholipase A2 OS2: the N-terminal region is more important than enzymatic activity
(2006-05)
Several snake venom secreted phospholipases A2 (sPLA2s) including OS2 exert a variety of pharmacological effects ranging from central neurotoxicity to anti-HIV activity by mechanisms that are not yet fully understood. To ...
Comparative study on the ability of IgG and F(ab')2 antivenoms to neutralize lethal and myotoxic effects induced by Micrurus nigrocinctus (coral snake) venom
(1999-08)
A comparative study was performed on the ability of IgG and F(ab')2 antivenoms to neutralize lethal and myotoxic activities of Micrurus nigrocinctus venom. Both antivenoms were adjusted to a similar neutralizing potency ...
Neutralization of local tissue damage induced by Bothrops asper (terciopelo) snake venom
(1998-11)
Local tissue damage represents a serious consequence of Bothrops asper envenomations. It encompasses a complex series of alterations, including myonecrosis, dermonecrosis, hemorrhage and edema. Due to its rapid development ...
Comparative study on the ability of IgG and Fab sheep antivenoms to neutralize local hemorrhage, edema and myonecrosis induced by Bothrops asper (terciopelo) snake venom
(2000-02)
The ability of sheep antivenoms, consisting of whole IgG molecules or Fab fragments, to neutralize local hemorrhage, edema and myonecrosis induced by Bothrops asper venom was comparatively studied in mice. The two antivenoms ...
