ABSTRACT
The morphogenetic program in the pathogenic fungus Candida albicans, including the dimorphic transition, is an interesting field of study, not only because it is absent in the commonly used model yeast Saccharomyces cerevisiae, but because of the close relationship between hyphal development and virulence of C. albicans. We studied one of the most important aspects of fungal morphogenesis-the septin ring-in C. albicans. By using a fusion construct to green fluorescent protein (GFP), the subcellular localization and dynamics of C. albicans Cdc10 in the different morphologies that this fungus is able to adopt was identified. The localization features reached were contrasted and compared with the results obtained from Candida cells directly extracted from an animal infection model under environmental conditions as similar as possible to the physiological conditions encountered by C. albicans during host infection (AU)
RESUMEN
La morfogénesis del hongo patógeno Candida albicans, incluyendo el fenómeno de transición dimórfica, es un interesante campo de estudio, no sólo por estar ausente en Saccharomyces cerevisiae, que es el modelo habitual de levadura en los estudios morfogenéticos, sino por la correlación existente entre virulencia y filamentación en C. albicans. Este trabajo describe el estudio de uno de los aspectos fundamentales de la morfogénesis fúngica, el anillo de septinas, en C. albicans. Usando el método de fusión con la proteína verde fluorescente (GFP), se identificó la localización subcelular y la dinámica de la septina Cdc10 de Candida albicans en las diferentes formas que puede adoptar este hongo. Los datos obtenidos se compararon y contrastaron con los logrados al extraer las células de Candida directamente de ratones previamente infectados con dicho hongo, en condiciones ambientales lo más parecidas posible a las condiciones fisiológicas que Candida encuentra al infectar un huésped (AU)
