ABSTRACT

BACKGROUND:

Mucor circinelloides is an opportunistic fungus capable of causing mucormycosis, a highly aggressive infection of quick spreading. Besides, it also has a high mortality rate due to late diagnosis and difficult treatment.

AIMS:

In this study we have identified the most immunoreactive proteins of the secretome and the total protein extract of M. circinelloides using sera from immunocompromised infected mice.

METHODS:

The proteins of the secretome and the total extract were analyzed by two-dimensional electrophoresis and the most immunoreactive antigens were detected by Western Blot, facing the sera of immunocompromised infected mice to the proteins obtained in both extracts of M. circinelloides.

RESULTS:

Seven antigens were detected in the secretome extract, and two in the total extract, all of them corresponding only to three proteins. The enzyme enolase was detected in both extracts, while triosephosphate isomerase was detected in the secretome, and heat shock protein HSS1 in the total extract.

CONCLUSIONS:

In this work the most immunoreactive antigens of the secretome and the total extract of M. circinelloides were identified. The identified proteins are well known fungal antigens and, therefore, these findings can be useful for future research into alternatives for the diagnosis and treatment of mucormycosis
RESUMEN
ANTECEDENTES Mucor circinelloides es un hongo oportunista causante de la mucormicosis, una infección altamente agresiva y de rápida expansión. Además, también presenta una alta mortalidad debido al diagnóstico tardío y el difícil tratamiento.

OBJETIVOS:

En este estudio se han identificado las proteínas más inmunorreactivas del secretoma y del extracto total de proteínas de M. circinelloides mediante el uso de sueros obtenidos de ratones inmunodeprimidos infectados.

MÉTODOS:

Las proteínas del secretoma y del extracto total se analizaron mediante electroforesis bidimensional y se detectaron los antígenos más inmunorreactivos mediante Western Blot, enfrentando el suero de los ratones inmunodeprimidos infectados a las proteínas obtenidas en ambos extractos de M. circinelloides.

RESULTADOS:

Se identificaron 7 antígenos en el secretoma y 2 en el extracto total, todos ellos correspondientes a 3 proteínas. La enolasa se detectó en ambos extractos, mientras que la triosafosfato isomerasa se detectó en el secretoma, y la proteína de choque térmico HSS1 en el extracto total.

CONCLUSIONES:

En este trabajo se identificaron los antígenos más inmunorreactivos del secretoma y del extracto total de M. circinelloides. Todas las proteínas identificadas son antígenos fúngicos muy conocidos y, por ello, estos resultados pueden ser de gran utilidad en futuras investigaciones relacionadas con la mejora del diagnóstico y el tratamiento de la mucormicosis
