Cerebellar deficit contributes significantly to disability in multiple sclerosis (MS). Several clinical and experimental studies have investigated the pathophysiology of cerebellar dysfunction in this neuroinflammatory disorder, but the cellular and molecular mechanisms are still unclear. In experimental autoimmune encephalomyelitis (EAE), a mouse model of(More)
Glutamate-mediated excitotoxicity is supposed to induce neurodegeneration in multiple sclerosis (MS). Glatiramer acetate (GA) is an immunomodulatory agent used in MS treatment with potential neuroprotective action. Aim of the present study was to investigate whether GA has effects on glutamate transmission alterations occurring in experimental autoimmune(More)
Multiple sclerosis (MS) causes a variety of motor and sensory deficits and it is also associated with mood disturbances. It is unclear if anxiety and depression in MS entirely reflect a subjective reaction to a chronic disease causing motor disability or rather depend on specific effects of neuroinflammation in neuronal circuits. To answer this question,(More)
Multiple sclerosis (MS) has long been regarded as a chronic inflammatory disease of the white matter that leads to demyelination and eventually to neurodegeneration. In the past decade, several aspects of MS pathogenesis have been challenged, and degenerative changes of the grey matter, which are independent of demyelination, have become a topic of(More)
Mood disturbances are frequent in patients with multiple sclerosis (MS), even in non-disabled patients and in the remitting stages of the disease. It is still largely unknown how the pathophysiological process on MS causes anxiety and depression, but the dopaminergic system is likely involved. Aim of the present study was to investigate depressive-like(More)
BACKGROUND AND PURPOSE Glutamate transmission is dysregulated in both multiple sclerosis (MS) and experimental autoimmune encephalomyelitis (EAE), the animal model of MS. A characteristic of EAE is increased glutamate transmission associated with up-regulation of AMPA receptors. However, little is known about the role of NMDA receptors in the synaptic(More)
A significant proportion of multiple sclerosis (MS) patients have functionally relevant cerebellar deficits, which significantly contribute to disability. Although clinical and experimental studies have been conducted to understand the pathophysiology of cerebellar dysfunction in MS, no electrophysiological and morphological studies have investigated(More)
Transient receptor potential vanilloid 1 (TRPV1) channels are involved in several inflammatory diseases. However, their action is still controversial, and both pro-inflammatory and anti-inflammatory roles have been described. We used a strain of TRPV1-KO mice to characterize the role of these channels in experimental autoimmune encephalomyelitis (EAE),(More)
Type-1 cannabinoid receptors (CB1R) are important regulators of the neurodegenerative damage in multiple sclerosis (MS) and in experimental autoimmune encephalomyelitis (EAE). In GABAergic striatal neurons, CB1R stimulation exerts protective effects by limiting inflammation-induced potentiation of glutamate-mediated spontaneous excitatory postsynaptic(More)
Microglia is increasingly recognized to play a crucial role in the pathogenesis of psychiatric diseases. In particular, microglia may be the cellular link between inflammation and behavioral alterations: by releasing a number of soluble factors, among which pro-inflammatory cytokines, that can regulate synaptic activity, thereby leading to perturbation of(More)
