Mipartoxin-I, a novel three-finger toxin, is the major neurotoxic component in the venom of the redtail coral snake Micrurus mipartitus (Elapidae)
(2012)The major venom component of Micrurus mipartitus, a coral snake distributed from Nicaragua to northern South America, was characterized biochemically and functionally. This protein, named mipartoxin-I, is a novel member ... -
MipLAAO, a new L-amino acid oxidase from the redtail coral snake, Micrurus mipartitus
(2018-06-08)L-amino acid oxidases (LAAOs) are ubiquitous enzymes in nature. Bioactivities described for these enzymes include apoptosis induction, edema formation, induction or inhibition of platelet aggregation, as well as antiviral, ... -
MmTX1 and MmTX2 from coral snake venom potently modulate GABAA receptor activity
(2015-02-24)GABAA receptors shape synaptic transmission by modulating Cl− conductance across the cell membrane. Remarkably, animal toxins that specifically target GABAA receptors have not been identified. Here, we report the discovery ... -
Modeling dengue cases in health Regions of Costa Rica using El Niño Southern Oscillation and local vegetation dynamics
(2009-11)Temporal behavior of dengue fever and dengue hemorrhagic fever (DH/DHF) has been associated with climate, which may modulate mosquito vector populations. El Niño Southern Oscillation (ENSO) fluctuations can be related to ... -

(2019)Brucella abortus es un patógeno intracelular bacteriano causante de la brucelosis bovina, una zoonosis desatendida de gran importancia mundial. Una vez entra a la célula hospedera B. abortus transita en un compartimento ... -
Modulation of the Susceptibility of Human Erythrocytes to Snake Venom Myotoxic Phospholipases A2: Role of Negatively Charged Phospholipids as Potential Membrane Binding Sites
(2001-07-01)Cerrophidion (Bothrops) godmani myotoxins I (CGMT-I) and II (CGMT-II), Asp-49 and Lys-49 phospholipases A(2) (PLA2s), which drastically differ in enzymatic activity, were devoid of direct hemolytic effects on erythrocytes ... -
Molecular architecture of the antiophidic protein DM64 and its binding specificity to myotoxin II from Bothrops asper venom
(2022)DM64 is a toxin-neutralizing serum glycoprotein isolated from Didelphis aurita, an ophiophagous marsupial naturally resistant to snake envenomation. This 64 kDa antitoxin targets myotoxic phospholipases A2, which account ... -
Molecular Characterization of Two Major Dengue Outbreaks in Costa Rica
(2016-07)Dengue virus (DENV) (Flavivirus, Flaviviridae) is a reemerging arthropod-borne virus with a worldwide circulation, transmitted mainly by Aedes aegypti and Aedes albopictus mosquitoes. Since the first detection of its ... -
