Inmunotoxicidad inducida por cianotoxinas: microcistinas y cilindrospermopsina

Abstract

Las cianobacterias son bacterias Gram negativas fotosintéticas capaces de producir floraciones a nivel mundial. Estas cianobacterias pueden producir también cianotoxinas perjudiciales para la salud de humanos, animales y plantas, y pueden actuar como hepatotoxinas, citotoxinas, neurotoxinas o dermatotoxinas. Las cianotoxinas de mayor in terés son las microcistinas (MC) y la cilindrospermopsina (CYN) por su extensa distribución y toxicidad. Aunque se conoce que principalmente las MC son hepatotóxica s y la CYN citotóxica , se ha observado que pueden producir alteraciones en otros órganos y s istemas, de los cuales el sistema inmune está aún escasamente estudiado. La presente revisión tiene, por tanto, como objetivo poner de manifiesto en modelos experimentales tanto in vitro como in vivo las alteraciones que se producen en el sistema inmune tr as la exposición a estas cianotoxinas y la importancia que ello tiene en la respuesta inmunitaria. Tras la realización de una búsqueda bibliográfica se seleccionaron veintitrés y siete artículos relacionados con la inmunotoxicidad de MC y CYN, respectivame nte. En ellos se evidencia el efecto de las MC sobre la proliferación de los linfocitos y la expresión de múltiples citoquinas, entre otros. Así mismo, se ha observado el efecto de la CYN sobre la viabilidad y capacidad de los linfocitos a pesar de que los estudios de inmunotoxicidad sobre ésta sean escasos. Por tanto, ambas cianotoxinas presentan potencial inmunotóxico que debería ser estudiado en mayor profundidad, especialmente en el caso de la CYN.
