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
Our group is interested in infections caused by the 8 known human herpes, which are very important etiological agents due to the high rates of infection, as well as their morbidity and mortality, especially in situations in which the immune system is immature (pediatric disease), senescent (pathologies in advanced age) or immunocompromised (transplanted).
They form a very heterogeneous group, but once the infection occurs, it persists for life through its latency phases. The pathogenicity of alpha- and beta-herpesviruses is related to primary infection and its recurrences, but in gamma-herpesviruses their main pathogenicity lies in their ability to produce tumors.
The main objective of the group is to respond to the medical problems caused by these infections from a multidisciplinary point of view, which includes virological, immunological and molecular aspects.
At present, the group's specific research objectives focus mainly on two topics:
Pathogenicity markers in congenital cytomegalovirus disease that modulate the immune system during infection and
Molecular characterization of the varicella zoster virus in cases of vaccine failure. The group's IP is part as a promoter partner of Spin-off: Virnóstica-ISCIII
