Time-dependent structural, functional and behavioural changes induced by acute stress at excitatory synapses in prefrontal and frontal cortex
Laboratory of Molecular and Cellular Pharmacology of Purinergic Transmission
Department of Pharmacological and Biomolecular Sciences, University of Milan
Stress deeply affects gene regulation, neurotransmission and synaptic morphology, and activate a stress response to restore homeostasis. However, when stress exposure is chronic, uncontrollable, or overwhelming, it represents a major risk factor for many diseases, including neuropsychiatric disorders.
Intriguingly, modifications of the glutamatergic system induced by stress in the prefrontal cortex seem to be biphasic. Indeed, while the fast response to stress suggests an enhancement in the number of excitatory synapses, synaptic transmission and working memory, long-term adaptive changes, including those consequent to chronic stress, induce opposite effects.
The identification of neural mechanisms underling resilience and vulnerability to stress is of crucial importance in the understanding of neuropsychiatric disorders pathophysiology and in the development of improved treatments.

Since 2001, this meeting represented an important event for basic and clinical researchers working on this emerging scientific topic. We will address state-of-the-art approaches in the field of steroids and nervous system, including behavior, epigenetics, genomic and non-genomic actions, the vitamin D, neurodegenerative and psychiatric disorders, and the interference among endocrine disruptors and steroid signaling.
Un malfunzionamento dei mitocondri, le centrali energetiche delle cellule, causa lo sviluppo della SCA28, una forma ereditaria di atassia. Dopo 10 anni di studi e grazie al sostegno di Fondazione Telethon, la scoperta del team di ricerca guidato dai proff. Alfredo Brusco e Filippo Tempia dell’Università di Torino e NICO. Lo studio pubblicato sulla prestigiosa rivista Neurobiology of Disease.
