Upregulation of a number of chemokines, including monocyte chemotactic protein-1 (MCP-1), is associated with Alzheimer's disease (AD) pathological changes. Emerging evidence suggests that inflammatory events precede the clinical development of AD, as cytokine disregulation has been observed also in patients with mild cognitive impairment (MCI). MCP-1 levels(More)
Monocyte chemoattractant protein-1 (MCP-1) and RANTES, as well as their related receptors, have been shown to be involved in Alzheimer's disease (AD) pathogenesis. Genes for their related receptors, CCR2 and CCR5, respectively, are characterized by the presence of two polymorphisms: a conservative change of a valine with an isoleucine at codon 64 of CCR2(More)
BACKGROUND Hereditary spastic paraplegias (HSP) are heterogeneous neurodegenerative disorders, genetically classified according to the identified disease gene or locus. Clinically, HSP are distinguished in pure and complicated forms. Mutations in the spastin gene (SPAST) are responsible for SPG4 and account approximately for 50% of the dominantly inherited(More)
Migraine is a primary headache characterized by recurrent attacks of head pain associated with nausea or vomit, photophobia, phonophobia and osmophobia. The presence of osmophobia during migraine attacks seems to be a very specific complaint. Cutaneous allodynia (CA) is very common in migraineurs, and it is the most evident clinical manifestation of central(More)
The distribution of the Glu298Asp polymorphism in NOS3 gene was determined in 405 Italian patients with "probable" Alzheimer's disease (AD) compared with 253 age-matched controls. Total plasma homocysteine (tHcy) levels were evaluated in 97 patients and 23 controls, and were correlated with the Glu298Asp genotype. A significantly increased frequency of the(More)
A common single nucleotide polymorphism (SNP), consisting in a T-->C transition (T-786C) in endothelial nitric oxide synthase (NOS3), has been reported to be associated with vascular pathologies, but no information are available on a possible association with AD. T-786C genotype was determined by polymerase chain reaction-restriction fragment length(More)
Interferon-gamma-inducible Protein-10 (IP-10) is supposed to play a role in Alzheimer's disease (AD) development, as demonstrated by increased levels in cerebrospinal fluid from patients with AD. A mutation scanning of IP-10 exonic region was carried out in 10 patients with AD and 10 age-matched controls, demonstrating the presence of two previously(More)
MCP-1 levels are increased in CSF of patients with Alzheimer's disease (AD) compared with controls, suggesting a role in the development of dementia. Recently, a biallelic A/G polymorphism in the MCP-1 promoter at position -2518 has been found, influencing the level of MCP-1 expression in response to an inflammatory stimulus. The distribution of the A-2518G(More)
We compared plasma levels of beta-amyloid 1-42 (pg/ml) found for 146 sporadic Alzheimer (AD) patients, 89 subjects with mild cognitive impairment (MCI) and 89 age-matched controls (CT). AD patients had significantly lower levels (38, 54, 52; p<0.01), unrelated to severity of the disease as assessed by MMSE score, age, sex or APOE4 status. Twenty cases(More)
About 60% of patients complain of cutaneous allodynia during migraine episodes, often in the periorbitary region of the pain side. Pre-clinical studies have shown that the underlying mechanism is sensitisation of primary nociceptors and central trigeminovascular neurons and that patients have a lower pain threshold for mechanical stimulation compared to(More)
