Dictyostelium discoideum, una ameba peculiar

Abstract

[CAT]: Dictyostelium discoideum és una ameba unicel·lular, encara que també presenta una etapa de desenvolupament multicel·lular en el seu cicle biològic. Aquest organisme ha estat utilitzat com un sistema model des de fa més de quaranta anys a causa de la seva similitud funcional amb les cèl·lules de mamífer. A més, mostra molts avantatges experimentals per a estudis de biologia i bioquímica de la cèl·lula. És genèticament manejable i molt accessible per a la manipulació experimental. Les cèl·lules de D. discoideum són molt mòbils i s’han utilitzat àmpliament en estudis del citosquelet cel·lular, la motilitat cel·lular i la migració quimiotàctica. El desenvolupament multicel·lular és relativament simple i ha estat un terreny fèrtil per a l’estudi de l’agregació, la diferenciació cel·lular, la morfogènesi i les vies genètiques i de senyalització que regulen aquests processos. A més, les cèl·lules de D. discoideum són cada vegada més utilitzades per a l’estudi de les malalties humanes. Per exemple, la interacció de cèl·lules amb bacteris patògens, el mecanisme d’acció de diferents drogues, la resistència als medicaments o les bases moleculars de les malalties humanes han estat recentment analitzats en aquest organisme model.

[EN]: Dictyostelium discoideum is a unicellular amoeba although it also presents a stage of multi-cellular development in its biological cycle. This organism has been used as a model system for over 40 years given its functional similarity to mammalian cells. In addition, it shows many experimental advantages for biochemical and cell biology studies. It is genetically tractable and highly accessible for experimental manipulation. D. discoideum cells are highly motile and have been extensively used in studies of the cellular cytoskeleton, cell motility and chemotactic migration. Multi-cellular development is relatively simple and has been a fertile ground for the study of aggregation, cell differentiation, morphogenesis, and the genetic and signalling pathways that regulate these processes. In addition D. discoideum cells are being increasingly used for the study of human disease. For example, cell interaction with bacterial pathogens, the mechanism of action of different drugs, drug resistance or the molecular basis of human diseases have been recently studied using this model organism.
