Evaluación del efecto del péptido sintético Pb53A derivado de toxinas de la araña Phoneutria boliviensis sobre la viabilidad celular de la línea HEK293 Authors: Bermúdez Urrego, Yair Santiago

“…The use of peptide toxins of animal origin is of great importance in modulating the activity of the NMDA receptor, which is associated with the excitotoxic phenomenon resulting from the increase in intracellular calcium concentration; an example is the Phoneutria boliviensis peptide toxins that show high homology with Phoneutria nigriventer peptide toxins that interact with the GluN2B subunit of the NMDA receptor. In this document we present the study of the cytotoxic effect that these peptides exert on the adherent eukaryotic cell line HEK-293, by means of the assay of the metabolic reduction of 3- (4,5-dimethylthiazol-2-yl) -2,5- bromide diphenyltetrazolium (MTT), as a preliminary assay for the evaluation of this peptide in the regulation of NMDAR receptor activity. …”
