Associate Professor (Docent) and Group Leader
In my lab we investigate host-pathogen interactions during bacterial infectious disease of the Central Nervous System.
I have studied Human Biology and Biomedical Sciences, bachelor and master, at the University of Pavia in Italy. After my undergraduate studies, I moved to the University Medical Center of Groningen, The Netherlands, to perform my PhD in Medical Microbiology under the supervision of Prof. Jan Maarten van Dijl and Prof. Grietje Molema studying how Streptococcus pneumoniae interact with endothelial cells causing invasive pneumococcal disease, in particular meningitis. During my PhD in 2010, I have been visiting PhD student in the lab of Prof. Carlos Orihuela in the Department of Microbiology and Immunology at the University of Texas Health Science Center in San Antonio, USA. My PhD studies on pneumococcal meningitis pathogenesis have been published by international microbiology and infectious diseases journals such as Cellular Microbiology, Infection and Immunity and mBio.
After my PhD graduation in November 2013, I have immediately started my postdoc in December 2013 at the Karolinska Institutet in the laboratory of Prof. Birgitta Henriques-Normark where I continued my studies on pneumococcal meningitis. My postdoc studies have been published in leading international journals like Journal of Clinical Investigation, Journal of Experimental Medicine, Journal of Infectious Diseases and Trends in Microbiology.
I was awarded in November 2018 with the 4-year funding for Assistant Professor position by the Karolinska Institutet Board of Research. I have then established my own research team within the Unit of Prof. Birgitta Henriques-Normark until December 2020. I am one of the 2020 awardee of Starting Grant in Medicine and Health from the Swedish Research Council (Vetenskapsrådet), and in January 2021 I have started my own laboratory of neuro-infections and neuro-inflammation at the Department of Neuroscience at Karolinska Institutet. My group investigates host-pathogen interaction during bacterial meningitis pathogenesis.

Neurological sequelae caused by meningitis: Interaction between pneumococci and neurons
Neurons are the main cell component of the brain, and mediate many functions controlled by the brain. Neurological sequelae caused by bacterial infection of the brain occur in 50% of meningitis survivors and are often related to neuronal damage. Our goal is to study how pneumococci can interact with neurons, invade and kill neuronal cells.

Blockade of pneumococcal interaction with neurons, a novel therapeutic strategy to prevent neuronal damage post-bacterial meningitis
Following up our recent discovery that ß-actin mediates pneumococcal binding to neuronal plasma membrane, we are now investigating novel approaches to block the interaction of S. pneumoniae with neuronal ß-actin to protect neurons during bacterial meningitis pathogenesis.
Study the role of neurons as "helper cells" in brain´s immunity towards bacterial infections
Neurons, as well as other eukaryotic cells, use the ubiquitin-proteasome system (UPS) and autophagy to degrade mis-folded proteins. Brain endothelial cells were previously shown to use the UPS system to kill intracellular pneumococci (https://journals.asm.org/doi/10.1128/mBio.00984-14). We want to investigate how neurons can use the UPS and autophagy to eliminate intracellular pneumococci and protect themselves from bacterial infections during meningitis pathogenesis.
The interplay between pneumococci and microglia, the primary immune cells of the brain
Study the biology of how microglia sense bacterial pathogens and initiate phagocytosis and/or neuroinflammatory process during meningitis pathogenesis; Study how pneumococci in the brain can survive and grow within microglia.

Study the pattern of entry of the brain by blood-borne S. pneumoniae
Using our bacteremia-derived meningitis mouse model and whole brain microscopy imaging, we want to identify what are the brain regions/lobes that are mostly affected by pneumococcal invasion upon penetration of the blood-brain barrier.
The relationship between bacterial meningitis and dementia
Many molecular processes, like the injury of neuronal cells and the neuro-inflammation process, are common in both bacterial meningitis and neurodegenerative diseases. We want to investigate to what extent the neuronal damage caused by a bacterial infection of the brain can increase the risk for onset of dementia, such as Parkinson´s disease. This project is a collaboration with the research groups of Prof. Gilberto Fisone (Department of Neuroscience, KI), Prof. Per Svenningsson (Department of Clinical Neuroscience, KI), Dr. Joana Pereira (Department of Neurobiology, Care Science and Society, KI), and Prof. Fang Fang (Institute of Environmental Medicine, KI).

Identification of new antimicrobial agents produced by placental amnion epithelial (AE) cells
Placental amnion epithelial (AE) cells can be isolated from a full-term placenta following live birth. AE cells have been previously reported to possess important immunomodulatory and anti-inflammatory properties, and have been proposed for the treatment of chronic inflammation. In this project, we investigate the capacity of AE cells to secrete molecules that have bactericidal activity against penicillin-resistant S. pneumoniae clinical isolates. Our goal is to establish a new antimicrobial treatment against penicillin-resistant bacterial pathogens. This project is a collaboration with the research group of Dr. Roberto Gramignoli (Department of Laboratory Medicine Huddinge, KI).
