Plasma Lipocalin 2 in Alzheimer's disease: potential utility in the differentia...
Hermann, Peter; Villar-Piqué, Anna; Schmitz, Matthias; Schmidt, Christian; Varges, Daniela; Goebel, Stefan; Bunck, Timothy; Lindemann, HannaBackground: Lipocalin-2 is a glycoprotein that is involved in various physiological and pathophysiological processes. In the brain, it is expressed in response to vascular and other brain injury, as well as in Alzheimer’s disease in reactive microglia and astrocytes. Plasma Lipocalin-2 has been proposed as a biomarker for Alzheimer’s disease but available data is scarce and inconsistent. Thus, we evaluated plas...
Cerebrospinal fluid lipocalin 2 as a novel biomarker for the differential diagn...
Llorens, Franc; Hermann, Peter; Villar-Piqué, Anna; Diaz-Lucena, Daniela; Nägga, Katarina; Hansson, Oskar; Santana, Isabel; Schmitz, MatthiasThe clinical diagnosis of vascular dementia (VaD) is based on imaging criteria, and specific biochemical markers are not available. Here, we investigated the potential of cerebrospinal fluid (CSF) lipocalin 2 (LCN2), a secreted glycoprotein that has been suggested as mediating neuronal damage in vascular brain injuries. The study included four independent cohorts with a total n = 472 samples. LCN2 was significa...
Evaluation of Human Cerebrospinal Fluid Malate Dehydrogenase 1 as a Marker in G...
Zerr, Inga; Villar-Piqué, Anna; Schmitz, Vanda Edit; Poleggi, Anna; Pocchiari, Maurizio; Sánchez-Valle, Raquel; Calero, Miguel; Calero, OlgaThe exploration of accurate diagnostic markers for differential diagnosis of neurodegenerative diseases is an ongoing topic. A previous study on cerebrospinal fluid (CSF)-mitochondrial malate dehydrogenase 1 (MDH1) in sporadic Creutzfeldt-Jakob disease (sCJD) patients revealed a highly significant upregulation of MDH1. Here, we measured the CSF levels of MDH1 via enzyme-linked immunosorbent assay in a cohort of...
α-synuclein interacts with PrPC to induce cognitive impairment through mGluR5 a...
Ferreira, Diana; Temido Ferreira, Mariana; Vicente Miranda, Hugo; Batalha, Vânia; Coelho, Joana E; Szegö, Éva M; Marques-Morgado, Inês; Vaz, Sandra H.Synucleinopathies, such as Parkinson's disease and dementia with Lewy bodies, are neurodegenerative disorders that are characterized by the accumulation of α-synuclein (aSyn) in intracellular inclusions known as Lewy bodies. Prefibrillar soluble aSyn oligomers, rather than larger inclusions, are currently considered to be crucial species underlying synaptic dysfunction. We identified the cellular prion protein ...
