Production and partial characterization of monoclonal antibodies to Bothrops asper (terciopelo) myotoxin
(1988)
Seven murine monoclonal antibodies against Bothrops aspen myotoxin were produced and partially characterized. They revealed the presence of at least four cross-reacting basic components in crude venom, with a common subunit ...
Membrane cholesterol modulates the cytolytic mechanism of myotoxin II, a Lys49 phospholipase A2 homologue from the venom of Bothrops asper
(2011-04-19)
Lys49 phospholipase A2 (PLA2) homologues present in crotalid snake venoms lack enzymatic activity, yet they induce skeletal muscle necrosis by a membrane permeabilizing mechanism whose details are only partially understood. ...
Pharmacological modulation of hyperalgesia induced by Bothrops asper (terciopelo) snake venom
(2001-08)
The ability of Bothrops asper snake venom to cause hyperalgesia was investigated in rats, using the paw pressure test. Intraplantar injection of the venom (5–15 μg/paw) caused a dose and time-related hyperalgesia, which ...
Accelerated biodegradation of selected nematicides in tropical crop soils from Costa Rica
(2014)
Degradation and mineralization behavior of select ed nematicides was studied in soil samples from fields culti vated with banana, potato, and coffee. Degradation assays in
most of the studied soils revealed shorter ...
A cellular deficiency of gangliosides causes hypersensitivity to Clostridium perfringens phospholipase C
(2005-07-22)
Clostridium perfringens phospholipase C (Cp-PLC), also called alpha-toxin, is the major virulence factor in the pathogenesis of gas gangrene. Previously, a cellular UDP-Glc deficiency was related with a hypersensitivity ...
Comparison of venom composition and biological activities of the subspecies Crotalus lepidus lepidus, Crotalus lepidus klauberi and Crotalus lepidus morulus from Mexico
(2013-08-01)
The rock rattlesnakes Crotalus lepidus comprise a group (lepidus, klauberi, morulus and
maculosus) of poorly known mountain cold-tolerant snakes in Mexico. In particular, Crotalus
lepidus morulus is a snake endemic of ...
Antivenomics and in vivo preclinical efficacy of six Latin American antivenoms towards south-western Colombian Bothrops asper lineage venoms
(2021)
Snakebite envenoming is an important occupational health problem, particularly in rural areas of developing countries. The timely administration of an effective antivenom remains the mainstay of snakebite management. ...
Identification of linear B-cell epitopes on myotoxin-II, a Lys49 phospholipase A2 homologue from Bothrops asper snake venom
(2012)
Knowledge on toxin immunogenicity at the molecular level can provide valuable information
for the improvement of antivenoms, as well as for understanding toxin structure–
function relationships. The aims of this study ...
Antibody neutralization of a myotoxin from the venom of Bothrops asper (terciopelo)
(1987)
Neutralization of biological activities of B. asper myotoxin by a monospecific anti-myotoxin rabbit serum and polyvalent antivenom was studied. Both antisera neutralized myotoxic, phospholipase A and lethal activities of ...
