Lemnitoxin, the major component of Micrurus lemniscatus coral snake venom, is a myotoxic and pro-inflammatory phospholipase A2
(2016-08-26)
The venom of Micrurus lemniscatus, a coral snake of wide geographical distribution in South America, was fractionated by reverse-phase HPLC and the fractions screened for phospholipase A2 (PLA2) activity. The major component ...
Immunochemical characterization of Micrurus nigrocinctus nigrocinctus venom with monoclonal and polyclonal antibodies
(1994)
Eleven murine monocloncal antibodies (MAbs) against Micrurus nigrocinctus nigrocinctus venom were produced and partially characterized. When M. n. nigrocinctus venom proteins were separated by SDS-PAGE under non-reducing ...
Phospholipase A2 myotoxins from Bothrops snake venoms [Artículo de revisión]
(1995-11)
Several myotoxins have been isolated from Bothrops snake venoms during the last 10 years. All of them are group II basic phospholipases A2, although some lack enzymatic activity (i.e. Lys-49 variants). These myotoxins ...
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 ...
Phospholipases A2: Unveiling the secrets of a functionally versatile group of snake venom toxins
(2013-02)
Phospholipases A2 (PLA2s) are abundant components of snake venoms, where they play toxic and digestive roles. Despite having a similar three-dimensional structure, venom PLA2s exert an amazing variety of toxic and ...
A phospholipase A2 from Bothrops asper snake venom activates neutrophils in culture: Expression of cyclooxygenase-2 and PGE2 biosynthesis
(2011-02)
In this study, the production of prostaglandin E2 (PGE2) and up-regulation in cyclooxygenase (COX) pathway induced by a phospholipase A2 (PLA2), myotoxin-III (MT-III), purified from Bothrops asper snake venom, in isolated ...
Omics Meets Biology: Application to the Design and Preclinical Assessment of Antivenoms
(Toxins vol.6:3388-3405, 2014-12-15)
Snakebite envenoming represents a neglected tropical disease that has a heavy public health impact worldwide, mostly affecting poor people involved in agricultural activities in Africa, Asia, Latin America and Oceania. A ...
Preclinical evaluation of the efficacy of antivenoms for snakebite envenoming: State-of-the-art and challenges ahead
(2017-05)
Animal-derived antivenoms constitute the mainstay in the therapy of snakebite envenoming. The efficacy of antivenoms to neutralize toxicity of medically-relevant snake venoms has to be demonstrated through meticulous ...
Snake venomics of the South and Central American Bushmasters. Comparison of the toxin composition of Lachesis muta gathered from proteomic versus transcriptomic analysis
(2008-04-30)
We report the proteomic characterization of the venoms of two closely related pit vipers of the genus Lachesis, L. muta (South American Bushmaster) and L. stenophrys (Central American Bushmaster), and compare the toxin ...
Discovery and optimization of a broadly-neutralizing human antibody against long-chain α-neurotoxins from snakes
(2023-02-08)
Snakebite envenoming continues to claim many lives across the globe, necessitating the development of improved therapies. To this end, broadly-neutralizing human monoclonal antibodies may possess advantages over current ...
