Role of the snake venom toxin jararhagin in proinflammatory pathogenesis: In vitro and in vivo gene expression analysis of the effects of the toxin
(2005-09)
To assess the indirect effects of snake venom metalloproteinases (SVMP) on host tissue local necrosis, we investigated the effect of the SVMP jararhagin on the gene expression profiles of human fibroblasts in vitro and ...
Tyr→Trp-substituted peptide 115-129 of a Lys49 phospholipase A2 expresses enhanced membrane-damaging activities and reproduces its in vivo myotoxic effect
(1999)
Myotoxin II is a group II Lys49 phospholipase A2 (PLA2) isolated from the venom of the snake Bothrops asper. Previous
studies on a synthetic peptide derived from its heparin-binding, cationic/hydrophobic sequence 115^129 ...
Effects on cultured mammalian cells of myotoxin III, a phospholipase A2 isolated from Bothrops asper (terciopelo) venom
(1993-11)
Myotoxin III (MT-III), a myotoxic phospholipase A2 from Bothrops asper, was studied with respect to interactions with cultured mammalian cells and red blood cells. Tests of the cytopathogenic effect of MT-III on different ...
Pharmacological modulation of edema induced by Lys-49 and Asp-49 myotoxic phospholipases A2 isolated from the venom of the snake Bothrops asper (terciopelo)
(1998-12)
The pharmacological modulation of edema-forming activity of Bothrops asper myotoxins II and III, Lys-49 and Asp-49 phospholipases A2, respectively, was studied plethysmographically in the mouse foot pad model. Myotoxin III ...
Local tissue damage induced by BaP1, a metalloproteinase isolated from Bothrops asper (Terciopelo) snake venom
(1995-12)
The pathogenesis of hemorrhage and other local effects induced by the metalloproteinase BaP1, isolated from Bothrops asper venom, was investigated using various in vivo and in vitro models. Upon intramuscular injection in ...
Immunohistochemical demonstration of the binding of bothrops asper myotoxin to skeletal muscle sarcolemma
(1987)
The binding of Bothrops asper myotoxin to mouse skeletal muscle was studied at both the light and electron microscope levels using the peroxidase anti-peroxidase technique. The toxin binds to muscle cell sarcolemma, and ...
Exploring the venom of the forest cobra snake: Toxicovenomics and antivenom profiling of Naja melanoleuca
(2017-01-06)
A toxicovenomic analysis of the venomof the forest cobra, N. melanoleuca,was performed, revealing the presence
of a total of 52 proteins by proteomics analysis. The most abundant proteins belong to the three-finger ...
Inflammatory infiltrate in skeletal muscle injected with Bothrops asper venom
(1986)
The time-course and composition of inflammatory infiltrate in mouse gastrocnemius injected with Bothrops asper venom was studied. The venom induced myonecrosis, and a prominent decrease in muscle levels of creatine kinase ...
Isolation and partial characterization of a myotoxin from the venom of the snake Bothrops nummifer
(1986)
A myotoxin from the venom of the snake Bothrops nummifer was purified to homogeneity by ion-exchange chromatography on CM-Sephadex. The toxin is a basic dimer with a subunit molecular weight of 16,000, as estimated by ...
Efecto de extractos de artrópodos sobre la multiplicación del Toxoplasma gondiidentro de macrófagos peritoneales de ratón
(Rev. Biol. Trop. 51(2): 317-320, 2003, 2003)
Treatment of toxoplasmosis usually causes secondary effects. It is important to find active substances extracted from natural organisms. In this work we studied some arthropod extracts that have effect against Toxoplasma ...
