Research Interests

Research area: Neuroimmunology, Neurodegeneration, Brain metabolism, Aging.
 

Current Research Topics:  The research is focus on glia cells activity to support brain activity in normal condition and in the process of aging.  Special focus is given to the role of glia in supporting essential brain metabolism using different mouse models such of stroke, Alzheimer's disease, Parkinson’s disease Huntington’s disease and multiple sclerosis.

 

 

Methods & Techniques: Neurobiology, Immunology, Metabolism, Cell biology, Molecular biology, Histology.

 

The  research in the laboratory focus  on glial-neuronal cell interactions to clarify their role in neurological diseases, both in culture and in animal models of different neurological diseases. The research is focus on the link between diabetes to neurological diseases. The laboratory combines approaches such as molecular biology, immunological approaches, histological approach, and behavioral approach to shed light on the genes and proteins involved in glial cell function, in particular microglia and astrocyte, in neurodegenerative diseases. The laboratory developed novel approaches to isolate adult glia from mice and to investigate their genetic and proteins profile that relate to pathological condition. Research focus on the link of glia failure to support brain metabolism in aging to the development neurodegenerative diseases. The laboratory develop and investigate new therapeutic approaches to treat neurological diseases such as Alzheimer’s disease and Parkinson’s diseases and has several approved patents.
