It has been extensively reported that diabetes mellitus (DM) patients have a higher risk of developing Alzheimer's disease (AD), but a mechanistic connection between both pathologies has not been provided so far. Carbohydrate-derived advanced glycation endproducts (AGEs) have been implicated in the chronic complications of DM and have been reported to play(More)
In response to peripheral nerve injury, Schwann cells adopt a migratory phenotype and modify the extracellular matrix to make it permissive for cell migration and axonal re-growth. Uridine 5'-triphosphate (UTP) and other nucleotides are released during nerve injury and activate purinergic receptors expressed on the Schwann cell surface, but little is known(More)
Semicarbazide-sensitive amine oxidase (SSAO) metabolizes the oxidative deamination of primary aromatic and aliphatic amines. The final cytotoxic products of its catalysis contribute to diseases involving vascular degeneration. The increasing interest in measuring SSAO activity has led to the development of several different methods. Herein, we compare SSAO(More)
Alzheimer's disease (AD) is a complex neurodegenerative disorder with a multifaceted pathogenesis. There are at present three Food and Drug Administration-approved drugs based on the "one drug, one target" paradigm (donepezil, galantamine and rivastigmine) that improve symptoms by inhibiting acetylcholinesterase. However, apart from the beneficial(More)
BACKGROUND Genome wide association studies reported two single nucleotide polymorphisms in ANK3 (rs9804190 and rs10994336) as independent genetic risk factors for bipolar disorder. Another SNP in ANK3 (rs10761482) was associated with schizophrenia in a large European sample. Within the debate on common susceptibility genes for schizophrenia and bipolar(More)
Alzheimer disease (AD) is a progressive dementia affecting a large proportion of the aging population. The histopathological changes in AD include neuronal cell death, formation of amyloid plaques and neurofibrillary tangles. There is also evidence that brain tissue in patients with AD is exposed to oxidative stress (e.g., protein oxidation, lipid(More)
Amyloid beta (Aβ) aggregation and deposition is a key pathological hallmark of AD. Growing evidence suggests that neurotoxicity of this peptide is related to the formation of toxic oligomeric aggregates. Therefore, a deeply investigated therapeutic strategy comes at present from blocking the formation of these species to non-toxic aggregates. Among other(More)
Schwann cells (SCs) are peripheral myelinating glial cells that express the neuronal Ca2+-dependent cell adhesion molecule, neural cadherin (N-cadherin). N-cadherin is involved in glia–glia and axon–glia interactions and participates in many key events, which range from the control of axonal growth and guidance to synapse formation and plasticity.(More)
Glial cells in the peripheral nervous system, such as Schwann cells, respond to nucleotides, which play an important role in axonal regeneration and myelination. Metabotropic P2Y receptor agonists are promising therapeutic molecules for peripheral neuropathies. Nevertheless, the proteomic mechanisms involved in nucleotide action on Schwann cells remain(More)
Autism spectrum disorders (ASD) comprise neurodevelopmental disorders with clinical onset during the first years of life. The identification of peripheral biomarkers could significantly impact diagnosis and an individualized, early treatment. Although the aetiology of ASD remains poorly understood, there is increasing evidence that neurotrophins and their(More)
