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 ...
Neutralization of coral snake Micrurus nigrocinctus venom by a monovalent antivenom
(1991)
The neutralizing ability of a monovalent anti-Micrurus nigrocinctus (coral snake) antivenom produced in Costa Rica was tested against the lethal, myotoxic and phospholipase A2 activities of homologous venom. In addition, ...
Isolation from a polyvalent antivenom of antibodies to a myotoxin in Bothrops asper snake venom
(1985)
Antibodies against Bothrops asper rmyotoxin were purified from a polyvalent antivenom by affinity chromatography . These antibodies neutralized most of the myotoxic activity of crude B. asper venom, as judged by histologic ...
Skeletal muscle necrosis and regeneration after injection of Thalassophryne nattereri (niquim) fish venom in mice
(2001-02)
Stings by Thalassophryne nattereri are responsible for envenomation of fishermen in north-eastern Brazil. Its venom induces prominent local tissue damage, characterized by pain, oedema and necrosis. The pathogenesis of ...
A snake venom secreted phospholipase A2 induces foam cell formation depending on the activation of factors involved in lipid homeostasis
(2018-06)
MT-III, a snake venom GIIA sPLA2, which shares structural and functional features with mammalian GIIA sPLA2s, activates
macrophage defense functions including lipid droplet (LDs) formation, organelle involved in both lipid ...
Antibody-dependent enhancement of toxicity of myotoxin II from Bothrops asper
(2024)
Improved therapies are needed against snakebite envenoming, which kills and
permanently disables thousands of people each year. Recently developed
neutralizing monoclonal antibodies against several snake toxins have ...
Snake venomics of the pit vipers Porthidium nasutum, Porthidium ophryomegas, and Cerrophidion godmani from Costa Rica: Toxicological and taxonomical insights
(2012-02-16)
Within the Neotropical pit vipers, a lineage of primarily Middle American snake species
referred to as the “Porthidium group” includes the genera Atropoides, Cerrophidion, and
Porthidium. In this study, the venom proteomes ...
Ability of fucoidan to prevent muscle necrosis induced by snake venom myotoxins: comparison of high- and low-molecular weight fractions
(2008)
Fucoidan, a natural polysaccharide extracted from brown seaweed, inhibits the myotoxic phospholipases A2 present in
the venoms of crotalid snakes. This study evaluated the influence of molecular weight on the ability of ...
Detection of proteins antigenically-related to Bothrops asper myotoxin in crotaline snake venoms
(1987)
The presence of components antigenically related to Bothrops asper myotoxin was investigated by Western blotting and immunoelectrophoretic techniques. B. asper myotoxin is a non-glycosylated monomeric phospholipase A with ...
Half a century of research on Bothrops asper venom variation: biological and biomedical implications
(2022)
Snake venoms are a complex biological mixture of proteins with or without enzymatic activity, peptides, and nucleotides, among other components. It is produced in specialized secretory glands located in the maxillary region, ...
