Citotoxicidad de nanopartículas metálicas en cultivos de células cerebrales

Abstract

Las nanopartículas (NP) se han investigado por su tamaño diminuto y su posibilidad de llegar a sitios específicos. Se estudian materiales para diseñar nanovectores inocuos. Son pocos los estudios de la exposición a diferentes NP que atraviesan la barrera hematoencefálica (BHE) y de los efectos que tienen sobre células en este tejido. Objetivo: determinar el deterioro celular en presencia de tres diferentes nanopartículas de origen metálico en cultivo de células cerebrales. Material y métodos: Realizamos un estudio de viabilidad con MTT y morfológico de cultivos cerebrales (glía y neurona) al contacto con concentraciones de: 10, 50 100 y 250 µg/ml de NP de óxido de silicio (NPSiO2), oro recubierto con silicio (NPAu@ Si) y plata (NPAg) Resultados: las células cerebrales se ven afectadas en su viabilidad y morfología, siendo más aparente la muerte celular con NPAg, con NPSiO2 se observa un descenso en la viabilidad de las mismas pero no tan severo como con NPAg, y para las NPAu@Si, se nota un poco más de resistencia incluso a la concentración más alta.
