PUBMED DOIAdditional Information
The AIDS Immunopathology Unit has been coordinated since 2000 by Dr. José Alcamí, bringing together during its history more than 20 independent researchers who collaboratively study different aspects of HIV infection. During this years, more than 30 visiting researchers and more than 50 national and international students have passed through the unit. From the beginning of the year 2025, Javier García Pérez and Francisco Díez Fuertes assumed the coordination of the AIDS Immunopathology Unit, with the aim of projecting its scientific competitiveness following multidisciplinary approaches and through the maintenance of the current close collaborations, as well as the promotion of participation in new national and international research networks.
Historically, the current members of the unit have focused on different lines of basic research that include the study of antibodies and the development of vaccines against HIV-1, the study of viral entry and tropism of the virus or the study of the host through the genomic characterization of populations with an extreme phenotype. Currently, the activity of our unit in the field of HIV-1 is focused on three main lines:
1. Mecanismos moleculares asociados a la protección de la infección por VIH-1 en pacientes con distrofia muscular de cinturas dominante D2 (LGMDD2).
2. Generación de anticuerpos neutralizantes de uso terapéutico basados en la respuesta neutralizante de amplio espectro frente a virus fundadores.
3. Cribado y caracterización de nuevos fármacos anti-latencia frente al VIH-1.
A partir del año 2020, nuestra unidad se vuelca con la investigación sobre COVID-19, participando y liderando diferentes proyectos de investigación aplicada y clínica. Fruto de esta fuerte implicación en el campo, en la actualidad se mantienen diferentes estudios sobre la caracterización de la respuesta inmune frente a SARS-CoV-2, integrando diferentes técnicas de virología molecular, estrategias de inteligencia epidemiológica y tecnologías de célula única.
We also participate in different research consortiums and networks, such as the Spanish AIDS Research Network or the Center for Biomedical Research in Infectious Diseases Network (CIBER-INFEC), in which we participate as researchers in different lines and work packages within the research programs “Global Health, emerging and re-emerging infections” as well as “HIV/AIDS and sexually transmitted infections”.
