Associate Professor (Docent), Principal Investigator and Group Leader
In my laboratory, we investigate bacterial interactions with brain cells during bacterial meningoencephalitis pathogenesis.
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 do 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 meningitis. 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 in mBio, Cellular Microbiology, Infection & Immunity, and PLOS One.
After my PhD graduation in November 2013, I have immediately started my postdoc in December 2013 at the Karolinska Institutet, Department of Microbiology, Tumor and Cell Biology (MTC), in the laboratory of Prof. Birgitta Henriques-Normark where I continued my studies on pneumococcal meningitis. My postdoc studies have been published in the leading journals Journal of Clinical Investigation, Journal of Experimental Medicine, Trends in Microbiology and Journal of Infectious Diseases.
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 at the Department of MTC until December 2020. I am one of the 2020 awardee of Starting Grant in Medicine and Health from the Swedish Research Council (Vetenskapsrådet). Because of my profound interest in nervous system infections, in January 2021 I have started my own independent laboratory of Neuro-Infections and Neuroinflammation at the Department of Neuroscience at Karolinska Institutet. I was appointed Docent (Associate Professor) in Medical Microbiology in December 2021 and Principal Researcher in April 2023.

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.
Study the pneumolysin release pattern of Streptococcus pneumoniae and its implication in neuronal cell damage
Pneumolysin is a pore-forming toxin released by Streptococcus pneumoniae and is known to damage the eukaryotic cells that gets in contact with. Pneumolysin is a conserved protein among pneumococcal serotypes, however it is not known if several isoforms of pneumolysin are released by different strains of S. pneumoniae. We want to investigate if different meningitis clinical isolates express and release different pneumolysins, and if different isoforms of pneumolysin have different pore-forming activity which can lead to different degrees of cytotoxicity towards eukaryotic cells, neurons in particular.
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).

Fluid dynamics in the brain during pneumococcal meningitis
The glymphatic system is responsible for solute exchange and clearance is a critical process to maintain proper brain homeostasis and take away from the brain harmful material. During pneumococcal meningitis, the glymphatic system's functionality is impaired and the lack of proper solute exchange process leads to a progressive accumulation in the brain of bacteria and bacterial toxic components with consequent neuroinflammation and neuronal damage. In this project, we investigate how physiological processes of the brain are altered during cerebral invasive infectious diseases and how we can translate our results into new therapeutic strategies to preserve solute exchange systems to protect the brain during infections.
