Amino acid sequence and crystal structure of BaP1, a metalloproteinase from Bothrops asper snake venom that exerts multiple tissue-damaging activities
(2003-10)
BaP1 is a 22.7-kD P-I-type zinc-dependent metalloproteinase isolated from the venom of the snake Bothrops asper, a medically relevant species in Central America. This enzyme exerts multiple tissue-damaging activities, ...
Isolation, characterization and molecular cloning of AnMIP, a new α-type phospholipase A2 myotoxin inhibitor from the plasma of the snake Atropoides nummifer (Viperidae: Crotalinae)
(2007)
A new phospholipase A2 (PLA2)-inhibitory protein was isolated from the plasma of Atropoides nummifer, a crotaline snake from Central
America. This inhibitor was named AnMIP, given its ability to neutralize the activity ...
Profiling the venom gland transcriptomes of Costa Rican snakes by 454 pyrosequencing
(BMC Genomics, 12:259, 2011, 2011)
Background: A long term research goal of venomics, of applied importance for improving current antivenom
therapy, but also for drug discovery, is to understand the pharmacological potential of venoms. Individually ...
Bacterial Sphingomyelinases and Phospholipases as Virulence Factors
(2016-06-15)
Bacterial sphingomyelinases and phospholipases are a heterogeneous group of esterases which are usually surface associated or secreted by a wide variety of Gram-positive and Gram-negative bacteria. These enzymes hydrolyze ...
In vitro Characterization of Anti-SARS-CoV-2 Intravenous Immunoglobulins (IVIg) Produced From Plasma of Donors Immunized With the BNT162b2 Vaccine and Its Comparison With a Similar Formulation Produced From Plasma of COVID-19 Convalescent Donors
(2022)
Despite vaccines are the main strategy to control the ongoing global COVID-19
pandemic, their effectiveness could not be enough for individuals with
immunosuppression. In these cases, as well as in patients with ...
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 ...
Antibody-mediated neutralization and binding-reversal studies on α-neurotoxins from micrurus nigrocinctus nigrocinctus (coral snake) venom
(1996-03)
An ELISA based, non-radioactive acetylcholine receptor (AchR) binding assay was used to detect the alpha-neurotoxins present in Micrurus nigrocinctus nigrocinctus venom. Sera from horses hyperimmunized against M. nigrocinctus ...
High Efficacy of Therapeutic Equine Hyperimmune Antibodies Against SARS-CoV-2 Variants of Concern
(2021)
SARS-CoV-2 variants of concern show reduced neutralization by vaccine-induced and
therapeutic monoclonal antibodies; therefore, treatment alternatives are needed. We
tested therapeutic equine polyclonal antibodies (pAbs) ...
Comparative study on the ability of IgG and F(ab')2 antivenoms to neutralize lethal and myotoxic effects induced by Micrurus nigrocinctus (coral snake) venom
(1999-08)
A comparative study was performed on the ability of IgG and F(ab')2 antivenoms to neutralize lethal and myotoxic activities of Micrurus nigrocinctus venom. Both antivenoms were adjusted to a similar neutralizing potency ...
Snake venomics and antivenomics: Proteomic tools in the design and control of antivenoms for the treatment of snakebite envenoming
(2009-03-06)
Snakebite envenoming represents a neglected tropical disease that has a heavy public health impact, particularly in Asia, Africa and Latin America. A global initiative, aimed at increasing antivenom production and ...
