Although several SARS-CoV-2 vaccines have ...
The Phospholipase A2 Homologues of Snake Venoms: Biological Activities and Their Possible Adaptive Roles
(2009)
A particular subgroup of toxins with phospholipase A2 (PLA2) structure, but devoid of this enzymatic activity, is commonly found in the venoms of snakes of the family Viperidae, and known as the PLA2 homologues. Among ...
Delayed oral LY333013 rescues mice from highly neurotoxic, lethal doses of Papuan Taipan (Oxyuranus scutellatus) venom
(2018)
There is an unmet need for economical snakebite therapies with long shelf lives
that are effective even with delays in treatment. The orally bioavailable, heat-stable, secretory
phospholipase A2 (sPLA2) inhibitor, LY333013, ...
Proteomic and toxicological analysis of the venom of Micrurus yatesi and its neutralization by an antivenom
(2022)
Coralsnakes belong to the family Elapidae and possess venoms which are lethal to humans and can be grouped based on the predominance of either three finger toxins (3FTxs) or phospholipases A2 (PLA2s). A proteomic and ...
Unresolved issues in the understanding of the pathogenesis of local tissue damage induced by snake venoms
(2018-06)
Snakebite envenoming by viperid species, and by some elapids, is characterized by a complex pattern of
tissue damage at the anatomical site of venom injection. In severe cases, tissue destruction may be so
extensive as ...
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 ...
Phospholipase A2 myotoxins from Bothrops snake venoms
(1995-11)
The genus Bothrops is distributed over all Latin America, From Mexico to Argentina, and comprises nearly 31 species of snake. In most of these countries, Bothrops spp. cause the majority of snake bit envenomations, which ...
Neutralization of myotoxic phospholipases A2 from the venom of the snake Bothrops asper by monoclonal antibodies
(1992)
The neutralization of two myotoxic phospholipases A2 from the venom of Bothrops asper, myotoxins I and II, by two murine monoclonal antibodies is reported. The monoclonal antibodies, MAb-3 and Mab-4, recognize different ...

costarricense, y posteriormente presentar las principales ...
Cytotoxicity of snake venom Lys49 PLA2-like myotoxin on rat cardiomyocytes ex vivo does not involve a direct action on the contractile apparatus
(2021-09)
Viperid snake venoms contain a unique family of cytotoxic proteins, the Lys49 PLA2 homologs, which are devoid of enzymatic activity but disrupt the integrity of cell membranes. They are known to induce skeletal muscle ...
