Spinal cord injury (SCI) is a devastating condition of the CNS for which there are no restorative therapies. Neuronal death at the primary lesion site and in remote regions that are functionally connected to it is one of the major contributors to neurological deficits induced by SCI. In this study we examined the crosstalk between mitochondria and the epigenome, defined as “mitonuclear communication” and its contribution to the remote damage-induced by SCI in the red nucleus (RN) contralateral to the injury site. Using a mouse model of SCI, we performed RNA-seq analysis on RN isolated from con

Cocaine use disorder (CUD) is a chronic neuropsychiatric condition characterized by a compulsion to use cocaine, resulting from enduring cellular and molecular adaptations. Among substance use disorders (SUDs), CUD is notable for its rising prevalence and the lack of approved pharmacotherapies. The nucleus accumbens (NAc), integral to the brain's reward circuitry, plays a crucial role in the initiation and continuation of maladaptive behaviors intrinsic to CUD. Leveraging advancements in neuroproteomics, we undertook an in-depth proteomic analysis of the NAc in a mouse model that spans membran

Aberrant insulin signalling was recently identified as a causative mechanism of Obsessive-Compulsive Disorder (OCD). Indeed, TALLYHO/JngJ mouse models of Type 2 diabetes are compulsive and anxious, with treatment with the Type 2 diabetes drug metformin generating partial rescue. Here, we aimed to establish the mechanisms behind this insulin-behavioural axis via proteomic analysis of brain and blood. Additionally, data from Genome-Wide Association studies (GWAS) of relevant disorders were compared using Ingenuity Pathway Analysis (IPA) (Qiagen). IPA analysis of proteomic results showed dysregul

Ageing is the greatest risk factor for cognitive decline and neurodegeneration. A characteristic of ageing is the loss of proteostasis. Neddylation maintains proteome homeostasis, it is involved in neuronal differentiation and its deregulation is linked to neurodegenerative diseases. The role and mechanisms of Neddylation with physiological ageing remain still unclear.We studied the expression and impact of neddylation on ageing and cognitive decline. We found that neddylation increases with age in the hippocampus neurogenic niche both in human and mouse samples. Aged, but not young, Nae1+/- h
