Immune Response Towards Snake Venoms 

León Montero, Guillermo; Sánchez Céspedes, Laura Vanessa; Hernández, Andrés; Villalta Arrieta, Mauren; Herrera Vega, María; Segura Ruiz, Álvaro; Estrada Umaña, Ricardo; Gutiérrez, José María (2011)
The immune response involves a complex repertoire of innate and adaptive responses to foreign agents in the organism. The present review focuses on the immune response to snake venoms, including those occurring in snakebite ...

Comparison of the adjuvant activity of aluminum hydroxide and calcium phosphate on the antibody response towards Bothrops asper snake venom 

Olmedo, Hidekel; Herrera Vega, María; Rojas Sánchez, Leonardo; Villalta Arrieta, Mauren; Vargas Arroyo, Mariángela; Leiguez, Elbio; Teixeira, Catarina de Fátima; Estrada Umaña, Ricardo; Gutiérrez, José María; León Montero, Guillermo; Montero Villalobos, Mavis Lili (2014)
The adjuvanticity of aluminum hydroxide and calcium phosphate on the antibody response in mice towards the venom of the snake Bothrops asper was studied. It was found that, in vitro, most of the venom proteins are similarly ...

Preclinical evaluation of caprylic-acid fractionated IgG antivenom for the treatment of taipan (Oxyuranus scutellatus) envneoming in Papua New Guinea 

Vargas Arroyo, Mariángela; Segura Ruiz, Álvaro; Herrera Vega, María; Villalta Arrieta, Mauren; Estrada Umaña, Ricardo; Cerdas Solís, Maykel; Paiva, Owen K.; Matainaho, Teatulohi; Jensen, Simon D.; Winkel, Kenneth D.; León Montero, Guillermo; Gutiérrez, José María; Williams, David J. (PLoS Neglected Tropical Diseases 5 (5) e1144, 2011-05-17)
Background: Snake bite is a common medical emergency in Papua New Guinea (PNG). The taipan, Oxyuranus scutellatus, inflicts a large number of bites that, in the absence of antivenom therapy, result in high mortality. ...

Intravenous administration of equine-derived whole IgG antivenom does not induce early adverse reactions in non-envenomed horses and cows 

Estrada Umaña, Ricardo; Herrera Vega, María; Segura Ruiz, Álvaro; Araya, Javier; Boschini Figueroa, Carlos; Gutiérrez, José María; León Montero, Guillermo (2010-11)
Administration of antivenoms to treat snakebite envenomings has the potential risk of inducing early adverse reactions. The mechanisms involved in these reactions are unclear. In this study, polyspecific antivenom consisting ...

Comparison of the effect of Crotalus simus and Crotalus durissus ruruima venoms on the equine antibody response towards Bothrops asper venom: Implications for the production of polyspecific snake antivenoms 

Dos Santos, María Cristina; Arroyo Portilla, Cynthia; Solano Rojas, Sergio; Herrera Vega, María; Villalta Arrieta, Mauren; Segura Ruiz, Álvaro; Estrada Umaña, Ricardo; Gutiérrez, José María; León Montero, Guillermo (2011-02)
Antivenoms are preparations of immunoglobulins purified from the plasma of animals immunized with snake venoms. Depending on the number of venoms used during the immunization, antivenoms can be monospecific (if venom from ...

Role of the animal model on the pharmacokinetics of equine-derived antivenoms 

Rojas Araya, Alicia; Vargas Arroyo, Mariángela; Ramírez Arguedas, Nils Antonio; Estrada Umaña, Ricardo; Segura Ruiz, Álvaro; Herrera Vega, María; Villalta Arrieta, Mauren; Gómez Argüello, Aarón; Gutiérrez, José María; León Montero, Guillermo (2013-08)
Antivenom pharmacokinetics has been studied in heterologous models in which the animal species used as immunoglobulin source is different from that used as recipient. In these models, after intravenous administration of ...

Snake venomics and antivenomics of Protobothrops mucrosquamatus and Viridovipera stejnegeri from Taiwan: Keys to understand the variable immune response in horses 

Villalta Arrieta, Mauren; Pla Ferrer, Davinia; Yang, Su Lin; Sanz, Libia; Segura Ruiz, Álvaro; Vargas Arroyo, Mariángela; Chen, Pei Yu; Herrera Vega, María; Estrada Umaña, Ricardo; Cheng, Ya Fen; Lee, Cheng Dow; Cerdas Solís, Maykel; Chiang, Jen Ron; Angulo Ugalde, Yamileth; León Montero, Guillermo; Calvete Chornet, Juan José; Gutiérrez, José María (2012-10-22)
The proteomes of the venoms of the snakes Viridovipera stejnegeri and Protobothrops mucrosquamatus from Taiwan were characterized by N-terminal sequencing, MALDI-TOF mass fingerprinting, and collision-induced dissociation ...

Impact of Regional Variation in Bothrops asper Snake Venom on the Design of Antivenoms: Integrating Antivenomics and Neutralization Approaches 

Gutiérrez, José María; Sanz, Libia; Flores Díaz, Marietta; Figueroa, Lucía; Madrigal Villalobos, Marvin; Herrera Vega, María; Villalta Arrieta, Mauren; León Montero, Guillermo; Estrada Umaña, Ricardo; Borges, Adolfo; Alape Girón, Alberto; Calvete Chornet, Juan José (2010-10-21)
Intraspecific snake venom variations have implications in the preparation of venom pools for the generation of antivenoms. The impact of such variation in the cross-reactivity of antivenoms against Bothrops asper venom was ...
