Cellular Neurobiology. Coordinator: Monti

Understanding the biochemical and molecular mechanisms in the cross-talk between glial cells (microglia, astrocytes or oligodendrocytes) and neurons in physiological conditions, as well as their alterations in neurodegenerative diseases to identify potential therapeutic targets.

Research themes

1. Microglia and astrocytes role in neuronal protection in physiopathological conditions: identification of proteic factors and miRNAs secreted by the glial cells both as soluble molecules and through exosomes in Amyotrophic lateral sclerosis, in collaboration with Dr. Zuccheri (FaBiT, Italy), granted by ALSA;

2. Neurons-oligodendrocytes interactions in ACG-1 deficiency: study of mutual signaling mechanisms between these cells under physiological conditions and their pathological alterations in the rare genetic, neurodegenerative and demyelinating disease, AGC-1 deficiency, by using both in vitro (cell lines, neurospheres and brain cell cultures derived from human iPS) and in vivo models in collaboration with Dr. Lasorsa (CNR, Bari, Italy), granted by Telethon.

3. Screening and characterization of the effect of small synthetic molecules on neuronal survival/death, neuron-glia regeneration and glial immunomodulation, in collaboration with Prof. Bolognesi (FaBiT, Italy).
