Susceptibilidad del huésped a las infecciones fúngicas invasoras
Se estima que más de un millón y medio de personas mueren al año en el mundo debido a una enfermedad fúngica invasora (EFI). Los tratamientos con inmunosupresores, terapias con corticoides, trasplantes de células hematopoyéticas y órgano sólido así como tratamientos quimioterapéuticos contra el cáncer han favorecido el aumento de estas infecciones fúngicas. El género Aspergillus es la principal causa de EFI por hongos filamentosos, siendo A. fumigatus la especie principalmente aislada en la mayoría de los casos y más frecuentemente asociada a Aspergilosis Invasora.
Muchas de estas infecciones están infra-diagnosticadas debido, tanto a la falta de sospecha clínica como a las limitaciones diagnósticas. Esta línea de investigación tiene como principal objetivo mejorar el pronóstico de la infecciones en pacientes con riesgo de desarrollar infecciones invasoras por hongos. Para ello se estudian marcadores del individuo (denominados biomarcadores del hospedador) que puedan ser detectados de forme temprana en muestras de pacientes en riesgo y que nos permita estratificar a los mismos en función de la susceptibilidad a desarrollar una infección invasora por hongos. Además, estudios realizados en los últimos años muestran que el fondo genético del hospedador está asociado con la predisposición al desarrollo de este tipo de enfermedades. En concreto se han identificado polimorfismos genéticos de nucleótido simple (“Single Nucleotide Polymorphism”- SNP) en genes que codifican para componentes celulares que interaccionan con estructuras fúngicas y/o que están involucradas en la respuesta inmune del huésped frente a agentes infecciosos como Aspergillus. En este sentido se han estandarizado y aplicado herramientas para la detección de SNPs en humanos de genes diana asociados concretamente con la susceptibilidad a la Aspergilosis Invasora.
Estudio de los mecanismos de virulencia en Aspergillus fumigatus
En paralelo al estudio de la respuesta del hospedador se sigue una línea cuyo objetivo es caracterizar mecanismos de virulencia en A. fumigatus. Uno de los principales mecanismos por los que A. fumigatus es capaz de causar enfermedad en humanos es su capacidad de adaptarse a las condiciones ambientales del hospedador. Entre las moléculas y los genes que se han relacionado con la virulencia de este hongo se encuentran componentes de la pared celular, genes y moléculas relacionadas con la evasión de la respuesta inmune, sistemas de detoxificación de los compuestos derivados del oxígeno, la producción de toxinas, la obtención de nutrientes como hierro, fósforo, nitrógeno y la adaptación a pH y temperatura del hospedador. Estos estudios permiten profundizar en el conocimiento sobre la patogenicidad de este hongo e identificar nuevas dianas terapéuticas

Leticia Bernal Martínez
Staff Scientist
ORCID code: 0000-0002-1694-5522
Dr. Bernal-Martínez obtained her degree in Biochemistry from the University of Zaragoza in 2005. She joined the Mycology Reference and Research Laboratory (LRIM) in 2006 under a trainee contract and completed her PhD within the Official Doctoral Program in Microbiology and Parasitology at the Complutense University of Madrid, defending her thesis in 2010 with highest honors (Cum Laude). In 2007, she continued her research activity at LRIM within the framework of the Spanish Network for Research in Infectious Diseases (REIPI). In 2016, she completed a Postgraduate Diploma in Promotion and Management of International Projects (Technical University of Madrid) and undertook a research stay at the Microbiology and Infection Research Domain, Life and Health Sciences Research Institute (ICVS), School of Health Sciences, University of Minho (Braga, Portugal). She was subsequently appointed as a PhD researcher within the Biomedical Research Networking Center in Infectious Diseases (CIBERINFEC). Since 2024, she serves as Specialist Scientist at the Carlos III Health Institute (ISCIII) and is responsible for the Diagnostic and Serology Section for Endemic Fungi at the Mycology Reference and Research Laboratory.
Dr. Bernal-Martínez has authored more than 30 peer-reviewed scientific publications and two book chapters. She has actively participated in over 12 research projects and has presented her work at numerous national and international scientific conferences. Her research has focused on human fungal infections, antifungal resistance, therapeutic drug monitoring, genetic variants associated with antifungal metabolism, and the identification of predictive biomarkers of invasive fungal infections. However, her primary expertise lies in the diagnostic field, particularly in the design, optimization, and validation of real-time PCR–based methodologies.
She is currently Principal Investigator of a research project aimed at improving current diagnostic techniques for invasive fungal infections, evaluating emerging diagnostic technologies, and studying primary fungal pathogens. A substantial part of her work has been transferred to the Spanish National Health System and to research centers in Latin America. Many of the diagnostic methodologies developed have been incorporated into the official service portfolio of ISCIII. She has collaborated with multiple hospitals through research projects and clinical trials applying these technologies, as well as with the ISCIII spin-off company Micomol S.L.
Dr. Bernal-Martínez has supervised several Master’s and Undergraduate Final Degree Projects from students at the Complutense University of Madrid and the University of Alcalá. She is a member of the teaching staff of the UNED-ISCIII PhD Program in Biomedical Sciences and Public Health and serves as lecturer in the Master’s Program in Public Health and Research in Infectious Diseases at the University of Alcalá. -

Laura Alcázar Fuoli
Research Scientist
Graduated in Biochemistry from the Autonomous University of Madrid and PhD in Biology from the Complutense University of Madrid in 2006. She completed her doctoral thesis at the National Center of Microbiology (CNM) under the direction of Dr. Emilia Mellado, in the study of the synthesis of Ergosterol in Aspergillus fumigatus. In 2012 Laura joined the reference laboratory in mycology with a researcher contract for the “Miguel Servet” program after having worked for three years as an associate researcher at Imperial College London. During that period his research focused on host adaptation mechanisms and virulence factors of A. fumigatus. In 2014 he obtained the position of Senior Scientist of Public Research Organizations carrying out his research work at the CNM.

Additional Information
The activity of this unit focuses on the development and clinical validation of point-of-care diagnostic methodology against liver viruses based on an emerging field, nanotechnology, a line of research that is developed in collaboration with BioAssays SL. Likewise, this unit focuses on delving into the immuno-virological mechanisms underlying viral infections and coinfections with other microorganisms and their influence on the host through a comprehensive approach to laboratory techniques.
One of the main lines of research involves the study of the coinfection of viral hepatitis with the Human Immunodeficiency Virus (HIV), evaluating the impact of coinfection and elimination of hepatitis C on the HIV reservoir, as well as its impact on virus-induced senescence, among others through the use of “omic” technologies.
Our group leads the Multidisciplinary HIV/Hepatitis Coinfection Group (COVIHEP), and maintains collaborations with national and international research groups of excellence, facilitating greater harmonization and quality in the biomedical research carried out. On the other hand, Dr. Briz maintains close collaboration with private companies, promoting intersectoral alliances that represent a competitive advantage.
