The immunoproteasome disturbs neuronal metabolism and drives neurodegeneration in multiple sclerosis

Veröffentlicht: von & gespeichert unter Allgemein.

Inflammation, aberrant proteostasis, and energy depletion are hallmarks of neurodegenerative diseases such as multiple sclerosis (MS). However, the interplay between inflammation, proteasomal dysfunction in neurons,and its consequences for neuronal integrity remains unclear. Using transcriptional, proteomic, and functional analyses of proteasomal subunits in inflamed neurons, we found that interferon-γ-mediated induction of the immunoproteasome subunit, proteasome 20S… Read more »

Neuroinflammation causes mitral cell dysfunction and olfactory impairment in a multiple sclerosis model.

Veröffentlicht: von & gespeichert unter Allgemein.

Background: Olfactory dysfunction is an underestimated symptom in multiple sclerosis (MS). Here, we examined the pathogenic mechanisms underlying inflammation-induced dysfunction of the olfactory bulb using the animal model of MS, experimental autoimmune encephalomyelitis (EAE). Results: Reduced olfactory function in EAE was associated with the degeneration of short-axon neurons, immature neurons, and both mitral and tufted… Read more »

Simvastatin as Add-On Treatment to Escitalopram in Patients With Major Depression and Obesity: A Randomized Clinical Trial.

Veröffentlicht: von & gespeichert unter Allgemein.

Importance: Major depressive disorder (MDD) and obesity are common noncommunicable disorders associated with substantial disease burden, which frequently occur comorbidly. Intriguingly, converging lines of evidence from animal models and genetic and observational studies have suggested a biological link between obesity, metabolic syndrome, and depression. Several small randomized clinical trials (RCTs) have suggested the antidepressive potential… Read more »
