  • Association of the RAGE G82S polymorphism with Alzheimer's disease
  • 2010

    • The receptor for advanced glycation end-products (RAGE) has been implicated in several pathophysiological processes relevant to Alzheimer's disease (AD), including transport and synaptotoxicity of AD-associated amyloid beta (A beta) peptides. A recent Chinese study (Li et al. in J Neural Transm 117:97-104, 2010) suggested an association between the 82S allele of the functional single nucleotide polymorphism (SNP) G82S (rs2070600) in the RAGE-encoding gene AGER and risk of AD. The present study aimed to investigate associations between AGER, AD diagnosis, cognitive scores and cerebrospinal fluid AD biomarkers in a European cohort of 316 neurochemically verified AD cases and 579 controls. Aside from G82S, three additional tag SNPs were analyzed to cover the common genetic variation in AGER. The 82S allele was associated with increased risk of AD (P (c) = 0.04, OR = 2.0, 95% CI 1.2-3.4). There was no genetic interaction between AGER 82S and APOE epsilon 4 in producing increased risk of AD (P = 0.4), and none of the AGER SNPs showed association with A beta(42), T-tau, P-tau(181) or mini-mental state examination scores. The data speak for a weak, but significant effect of AGER on risk of AD.

  • Is there a CSF biomarker profile related to depression in elderly women?
  • 2010
  • Ingår i: Psychiatry Research. - 0165-1781. ; 176:2-3, s. 174-178
  • Tidskriftsartikel (refereegranskat)abstract
    • In light of our previous observation of higher levels of cerebrospinal fluid (CSF) amyloid beta-42 (Aβ42) and CSF/serum albumin ratio in major depressive disorder (MDD), we analyzed two additional CSF biomarkers reflecting neurodegeneration—neurofilament protein light (NFL) and glial fibrillary acidic protein (GFAp)—in relationship to prevalent geriatric depression. Neuropsychiatric, physical, and lumbar puncture examinations, with DSM-III-R-based depression diagnoses and measurement of CSF levels of NFL and GFAp, were evaluated among a population-based sample of 78 elderly women (mean age, 73.9±3.2 years) without dementia for at least 10 years after CSF collection. Eleven (13.1%) women had MDD, and higher levels of NFL compared with women without depression. A multivariate model including age, NFL, Aβ42 and the CSF/serum albumin ratio showed that each biomarker was independently and positively associated with MDD, and that this biomarker profile explained more variation in the model compared with single or combined biomarkers. A CSF profile with higher levels of NFL, Aβ42, and CSF/serum albumin ratio may indicate neuropathological and vascular events in depression etiology. This contrasts with the well-characterized pattern of low Aβ42, higher CSF/serum albumin ratio, and higher NFL in Alzheimer's disease.

  • Cerebrospinal fluid beta-amyloid 1-42 concentration may predict cognitive decline in older women.
  • 2007
  • Ingår i: Journal of neurology, neurosurgery, and psychiatry. - 1468-330X. ; 78:5, s. 461-4
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Low levels of cerebrospinal fluid (CSF) beta-amyloid 1-42 (Abeta42) and high total tau (T-tau) are diagnostic for manifest Alzheimer's disease. It is not known, however, whether these biomarkers may be risk indicators for cognitive decline in otherwise healthy older people. METHODS: The longitudinal relationship between CSF markers, Abeta42 and T-tau, measured in 1992, and change in Mini-Mental State Examination (deltaMMSE) score between 1992 and 2002 were investigated in 55 women (aged 70-84 years, mean (SD) MMSE score = 28.3 (1.5)), who were participants in the Prospective Population Study of Women in Gothenburg, Sweden. These women did not have dementia when they experienced lumbar puncture in 1992-3. RESULTS: Over the 8-year follow-up period, deltaMMSE (range = +3 to -21 points) was correlated with Abeta42 (Spearman's r = 0.40, p = 0.002), such that lower levels of Abeta42 were related to greater decline. This was also observed after excluding 4 women who developed dementia between 1992 and 2002 (Spearman's r = 0.34, p = 0.019). A multivariate logistic regression model predicting a decline of > or = 5 points on the MMSE (observed in six women), or a risk of developing dementia over the 8-year follow-up period (observed in four women), including age, education, Abeta42 and T-tau as covariates, showed that Abeta42 was the sole predictor of significant cognitive decline or dementia (OR per 100 pg/ml Abeta42 = 2.24, 95% CI 1.19 to 4.22, p = 0.013). CONCLUSIONS: Low levels of CSF Abeta42 may predict cognitive decline among older women without dementia.
