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
Streptococcus pneumoniae is a human pathogen that, despite the development of vaccines, continues to be an important cause of mortality and morbidity. We investigate the mechanisms of antibiotic resistance in this bacterium. On the one hand by identifying new therapeutic targets and on the other hand by investigating the molecular basis of the action of antibiotics already used in clinical practice (the fluoroquinolones levofloxacin and moxifloxacin) or not yet used (seconeolitsine). For this purpose, we used a multidisciplinary analysis involving genomics, transcriptomics and proteomics to understand the organization of the S. pneumoniae chromosome and the identification of the factors that stabilize this organization, including ncRNAs. Changes in the level of global supercoiling, either by inhibition of gyrase (decrease) or by inhibition of topoisomerase I (increase) alter the transcriptome. The modulated genes are located in domains, whose genes show specific functional characteristics. The aim is to identify new factors essential for S. pneumoniae physiology and to characterize transcriptional regulation in response to topological stress. In addition, RNA interference technology and CRISPR systems will be used as novel antibacterials. These studies will establish the bases for translational research aimed at the development of new therapeutic targets for the treatment of pneumococcal diseases.
