Claudia Nobrega research interest is related to the involvement of the immune system on multiple sclerosis (MS) pathophysiology.
Using a homogenous group of relapsing-remitting MS (RRMS) and of primary progressive MS (PPMS) patients, newly-diagnosed and treatment-naïve, Claudia and her colleagues reported that, in comparison to healthy controls, patients’ T cell phenotype in the blood tips towards a less differentiated phenotype. Following this observation, they were granted the opportunity to explore the mechanisms underlying this, and to understand how this observation can be integrated in the current model of MS pathophysiology. Additionally, and in line with the recent compelling evidence supporting that infection with the Epstein-Barr virus (EBV) precedes MS, Claudia and her colleagues are also interested in assessing the function and the T cell receptor (TCR) repertoire of EBV specific CD8+ T cells from MS vs. EBV-seroconverted controls.
Claudia completed her PhD in 2009 studying the impact of thymic infection by mycobacteria on the differentiation of new T cells. Her Post-Doc was a turning point when she embraced human studies, to complement the mouse models she had been working with so far. She followed her interest in immunology in the context of chronic diseases, namely on infections by HIV and Mycobacterium tuberculosis, and more recently on MS. In these studies, gained traction on the implementation, nurturing and organization of biobanks of human samples (serum/plasma and PBMCs), maintenance of the respective data bases and fostering interaction and collaboration with the clinicians.
