Horacio Gil Gil
Research Scientist
ORCID code: 0000-0002-7114-6686
Degree in Veterinary Medicine in 1995 and PhD in Veterinary Medicine in 2002 from the University of Zaragoza. He did his PhD thesis at NEIKER Tecknalia (Derio, Vizcaya) and the National Center for Microbiology of Instituto de Salud Carlos III (CNM-ISCIII, Majadahonda, Madrid) on the biological cycle of Lyme disease in the Basque Country. After that, he developed his postdoctoral training in different aspects of the pathogenesis of tularemia at the Center for Infectious Diseases, Stony Brook University, New York (USA) for 3 years. In December 2005, he joined the Reference and Research Laboratory in Special Pathogens of the CNM-ISCIII where he developed diagnostic, reference and research activities, in Bartonella, Leptospira and pathogens of interest in bioterrorism. Between 2014-2016 he participated in the European Program for the Training of Microbiologists in Public Health (EUPHEM), organized by the European Centre for Disease Prevention and Control. During this program, he participated in an international mission for the investigation of a cholera outbreak in Ghana, proposed by the Bernhard Nocht Institute for Tropical Diseases in Hamburg (Germany). In December 2016, he worked as a laboratory consultant for the World Health Organization at their office in Phnom Penh (Cambodia). Subsequently, he worked one year with Médecins Sans Frontières as director and quality manager of the TB laboratory in Nukus (Uzbekistan).
In 2019, he joined the HIV Variability and Biology Unit at CNM-ISCIII, where he developed different reference and research activities, including his contribution to the molecular epidemiological surveillance of HIV-1 in Spain and the study of HIV-1 antiretroviral resistance. Since September 2022 he has been leading the Human Papillomavirus Unit at the CNM-ISCIII. -

Additional Information
The group is interested in the study of the immune response from a multidisciplinary perspective that includes genomic, biochemical, proteomic, in vivo and biotechnological models aimed at the design of therapeutic strategies against various chronic, infectious and rare diseases that have a clear immunological component in their etiology.
The current specific objectives focus on:
- Antigenic presentation: Identification of antigenic presentation rules for their application in the design of therapeutic treatments including vaccines.
- Study of CD69 function and its regulation; its use as a therapeutic target in the mobilization of hematopoietic precursors and in the potentiation of the immune response mediated by CD69 with the potentiation of vaccines using the vaccinia virus as a vector.
