The glycoprotein, CD200, is primarily expressed on neurons and its cognate receptor CD200R is expressed principally on cells of the myeloid lineage, including microglia. The interaction of CD200 with its receptor plays a significant role in maintaining microglia in a quiescent state and therefore a decrease in CD200 expression in brain is associated with(More)
Increasing global birth rate, coupled with the aging population surviving into their eighth decade has lead to increased incidence diseases, hitherto designated as rare. Brain related ischemia, at birth, or later in life, during, for example stroke, is increasing in global prevalence. Reactive microglia can contribute to neuronal damage as well as(More)
Amyloid-beta (Abeta) peptides, the primary component of the amyloid plaques in Alzheimer's disease (AD), exert profound effects on neurons in vitro and negatively impact on neuronal function in vivo. One of the consequences of increased Abeta in the brain, either as a result of overexpression of the precursor amyloid precursor protein in transgenic mice, or(More)
Biobanks are important resources for biomarker discovery and assay development. Biomarkers for Alzheimer's and Parkinson's disease (BIOMARKAPD) is a European multicenter study, funded by the EU Joint Programme-Neurodegenerative Disease Research, which aims to improve the clinical use of body fluid markers for the diagnosis and prognosis of Alzheimer's(More)
BACKGROUND A common change that occurs with age in the central nervous system is an increase in microglial-associated inflammation. This is usually coupled with an increase in the concentration of the inflammatory cytokine interleukin-1beta (IL-1beta) in the hippocampus and an inhibition in long-term potentiation. OBJECTIVES To assess the effects of a(More)
BACKGROUND Assay-vendor independent quality control (QC) samples for neurochemical dementia diagnostics (NDD) biomarkers are so far commercially unavailable. This requires that NDD laboratories prepare their own QC samples, for example by pooling leftover cerebrospinal fluid (CSF) samples. OBJECTIVE To prepare and test alternative matrices for QC samples(More)
AIM Neurofilament light (NfL) chain, a putative cerebrospinal fluid biomarker, can support neurodegenerative disease diagnosis and indicate disease severity and prognosis. Universal validation protocols when used to measure biomarkers can reduce pre and analytical laboratory variation, thus increasing end-user confidence in the consistency of validation(More)
The family of reticulons include three isoforms of the Nogo protein, Nogo A, Nogo B and Nogo C. Nogo A is expressed on neuronal tissue and its primary effect is widely acknowledged to be inhibition of neurite outgrowth. Although both Nogo B and Nogo C are also expressed in neuronal tissue, their roles in the CNS remain to be identified. In this study, we(More)
BACKGROUND BIOMARKAPD seeks to diminish the barriers associated with the clinical use of cerebrospinal fluid (CSF) biomarker analysis by reducing variation in CSF laboratory methodologies and generating consensus recommendations on their clinical interpretation and application for dementia diagnosis. OBJECTIVE To examine the disparity in practitioner(More)
