Bothrops snake myotoxins induce a large efflux of ATP and potassium with spreading of cell damage and pain
(2010-07-26)
Myotoxins play a major role in the pathogenesis of the envenomations caused by snake bites in large parts of the world where this is a very relevant public health problem. We show here that two myotoxins that are major ...
Characterization of a novel snake venom component: Kazal-type inhibitor-like protein from the arboreal pitviper Bothriechis schlegelii
(2016-06)
Snake venoms are composed mainly of a mixture of proteins and peptides. Notably, all snake venom toxins have been assigned to a small number of protein families. Proteomic studies on snake venoms have recently identified ...
A new muscle damaging toxin, myotoxin II, from the venom of the snake Bothrops asper (terciopelo)
(1989)
A new muscle damaging toxin, myotoxin II, was purified from the venom of Bothrops asper by ion-exchange chromatography on CMSephadex C-25. The toxin is a dimeric, basic protein with a monomer mol.wt of 13,341, according ...
Human heterophilic antibodies against equine immunoglobulins: assessment of their role in the early adverse reactions to antivenom administration
(2008)
The presence of human heterophilic antibodies against horse immunoglobulins
(HHA-HI) was determined by ELISA in sera from healthy volunteers and from patients who
received equine antivenom for therapy of snake bite ...
The dynamics of local tissue damage induced by Bothrops asper snake venom and myotoxin II on the mouse cremaster muscle: an intravital and electron microscopic study
(1994-01)
The acute tissue damaging effects of Bothrops riper snake
venom and a myotoxic Lys-49 phospholipase A2 (myotoxin In on the mouse
cremaster muscle were studied by intravital and electron microscopy. Both
venom and myotoxin ...
Isolation and biochemical, functional and structural characterization of a novel L-amino acid oxidase from Lachesis muta snake venom
(2012-12-01)
The aim of this study was the isolation of the LAAO from Lachesis muta venom (LmLAAO) and its biochemical, functional and structural characterization. Two different purification protocols were developed and both provided ...
Proteomic profiling, functional characterization, and immunoneutralization of the venom of Porthidium porrasi, a pitviper endemic to Costa Rica
(2019)
The genus Porthidium includes nine pitviper species inhabiting Mexico, Central America, and northern South
America. Porthidium porrasi is a species endemic to the Southwest of Costa Rica, for which no information on ...
Histopathological and biochemical alterations induced by intramuscular injection of Bothrops asper (terciopelo) venom in mice
(1989)
The local and systemic pathological changes induced by an i.m. injection of 100 micrograms of Bothrops asper venom in mice were studied histologically and by following the changes in serum levels of enzymes, proteins, ATP ...
Unveiling the nature of black mamba (Dendroaspis polylepis) venom through venomics and antivenom immunoprofiling: identification of key toxin targets for antivenom development.
(2015-04-24)
The venom proteome of the black mamba, Dendroaspis polylepis, from Eastern Africa, was, for the first time, characterized. Forty- different proteins and one nucleoside were identified or assigned to protein families. The ...
Venom, venomics, antivenomics
(2009)
Venoms comprise mixtures of peptides and proteins tailored by Natural Selection to act on vital systems
of the prey or victim. Here we review our proteomic protocols for uncoiling the composition,
immunological profile, ...
