Longitudinal studies that investigate courses of neuropsychological and other variables screen for such predictors correlated to mild cognitive impairment (MCI). However, one often neglected issue in analyses of such studies is measurement invariance (MI), which is often assumed but not tested for. This study uses the absence of MI (non-MI) and latent factor scores instead of composite variables to assess properties of cognitive domains, compensation mechanisms, and their predictability to establish a method for a more comprehensive understanding of pathological cognitive decline. Methods An exploratory factor analysis (EFA) and a set of increasingly restricted confirmatory factor analyses (CFAs) were conducted to find latent factors, compared them with the composite approach, and to test for longitudinal (partial-)MI in a neuropsychiatric test battery, consisting of 14 test variables. A total of 330 elderly (mean age: 73.78 ± 1.52 years at baseline) were analyzed two times (3 years apart). Results EFA revealed a four-factor model representing declarative memory, attention, working memory, and visual-spatial processing. Based on CFA, an accurate model was estimated across both measurement timepoints. Partial non-MI was found for parameters such as loadings, test- and latent factor intercepts as well as latent factor variances. The latent factor approach was preferable to the composite approach. Conclusion The overall assessment of non-MI latent factors may pose a possible target for this field of research. Hence, the non-MI of variances indicated variables that are especially suited for the prediction of pathological cognitive decline, while non-MI of intercepts indicated general aging-related decline. As a result, the sole assessment of MI may help distinguish pathological from normative aging processes and additionally may reveal compensatory neuropsychological mechanisms.}, language = {en} } @article{FareedQasmiAzizetal.2022, author = {Fareed, Muhammad Mazhar and Qasmi, Maryam and Aziz, Shaan and V{\"o}lker, Elisabeth and F{\"o}rster, Carola Yvette and Shityakov, Sergey}, title = {The role of clusterin transporter in the pathogenesis of Alzheimer's disease at the blood-brain barrier interface: a systematic review}, series = {Biomolecules}, volume = {12}, journal = {Biomolecules}, number = {10}, issn = {2218-273X}, doi = {10.3390/biom12101452}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-290279}, year = {2022}, abstract = {Alzheimer's disease (AD) is considered a chronic and debilitating neurological illness that is increasingly impacting older-age populations. Some proteins, including clusterin (CLU or apolipoprotein J) transporter, can be linked to AD, causing oxidative stress. Therefore, its activity can affect various functions involving complement system inactivation, lipid transport, chaperone activity, neuronal transmission, and cellular survival pathways. This transporter is known to bind to the amyloid beta (Aβ) peptide, which is the major pathogenic factor of AD. On the other hand, this transporter is also active at the blood-brain barrier (BBB), a barrier that prevents harmful substances from entering and exiting the brain.

Aβ deposits and NFT formation are the central pathological hallmarks in AD brains, and the majority of AD cases have been shown to exhibit a complex combination of systemic comorbidities. While AD is the foremost common cause of dementia in the elderly, age-related hearing loss (ARHL) is the most predominant sensory deficit in the elderly. During aging, chronic inflammation and resulting endothelial dysfunction have been described and might be key contributors to AD; we discuss an intriguing possible link between inner ear strial microvascular pathology and blood-brain barrier pathology and present ARHL as a potentially modifiable and treatable risk factor for AD development. We present compelling evidence that ARHL might well be seen as an important risk factor in AD development: progressive hearing impairment, leading to social isolation, and its comorbidities, such as frailty, falls, and late-onset depression, link ARHL with cognitive decline and increased risk of dementia, rendering it tempting to speculate that ARHL might be a potential common molecular and pathological trigger for AD. Additionally, one could speculate that amyloid-beta might damage the blood-labyrinth barrier as it does to the blood-brain barrier, leading to ARHL pathology. Finally, there are options for the treatment of ARHL by targeted neurotrophic factor supplementation to the cochlea to improve cognitive outcomes; they can also prevent AD development and AD-related comorbidity in the future.}, language = {en} } @article{GentzschChenSpatzetal.2021, author = {Gentzsch, Christian and Chen, Xinyu and Spatz, Philipp and Košak, Urban and Knez, Damijan and Nose, Naoko and Gobec, Stanislav and Higuchi, Takahiro and Decker, Michael}, title = {Synthesis and Initial Characterization of a Reversible, Selective \(^{18}\)F-Labeled Radiotracer for Human Butyrylcholinesterase}, series = {Molecular Imaging and Biology}, volume = {23}, journal = {Molecular Imaging and Biology}, number = {4}, issn = {1860-2002}, doi = {10.1007/s11307-021-01584-2}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-269870}, pages = {505-515}, year = {2021}, abstract = {Purpose A neuropathological hallmark of Alzheimer's disease (AD) is the presence of amyloid-β (Aβ) plaques in the brain, which are observed in a significant number of cognitively normal, older adults as well. In AD, butyrylcholinesterase (BChE) becomes associated with A\(_{β}\) aggregates, making it a promising target for imaging probes to support diagnosis of AD. In this study, we present the synthesis, radiochemistry, in vitro and preliminary ex and in vivo investigations of a selective, reversible BChE inhibitor as PET-tracer for evaluation as an AD diagnostic. Procedures Radiolabeling of the inhibitor was achieved by fluorination of a respective tosylated precursor using K[\(^{18}\)F]. IC\(_{50}\) values of the fluorinated compound were obtained in a colorimetric assay using recombinant, human (h) BChE. Dissociation constants were determined by measuring hBChE activity in the presence of different concentrations of inhibitor. Results Radiofluorination of the tosylate precursor gave the desired radiotracer in an average radiochemical yield of 20 ± 3 \%. Identity and > 95.5 \% radiochemical purity were confirmed by HPLC and TLC autoradiography. The inhibitory potency determined in Ellman's assay gave an IC\(_{50}\) value of 118.3 ± 19.6 nM. Dissociation constants measured in kinetic experiments revealed lower affinity of the inhibitor for binding to the acylated enzyme (K2 = 68.0 nM) in comparison to the free enzyme (K\(_{1}\) = 32.9 nM).

As the respiratory tract connects to the brain without protection of the blood-brain barrier, SARS-CoV-2 might in the early invasive phase attack the cardiorespiratory centres located in the medulla/pons areas, giving rise to disturbances of respiration and cardiac problems. Furthermore, brainstem regions are at risk to lose their functional integrity. Therefore, long-term neurological as well as psychiatric symptomatology and eventual respective disorders cannot be excluded as evidenced from influenza-A triggered post-encephalitic Parkinsonism and HIV-1 triggered AIDS-dementia complex.

SARS-CoV-2 mirroring experimental animal brain studies, characterization of time-dependent and region-dependent spreading behaviours of coronaviruses, enlightening of pathological mechanisms after coronavirus infection using long-term animal models and clinical observations of patients having had COVID-19 infection are calling to develop both protective strategies and drug discoveries to avoid early and late coronavirus-induced functional brain disturbances, symptoms and eventually disorders.

Previously, we showed in an in vivo study that 3 months after STZ icv treatment hippocampal adult neurogenesis (AN) is impaired. In the present study, we examined the effects of STZ on isolated adult hippocampal neural stem cells (NSCs) using an in vitro approach. We revealed that 2.5 mM STZ inhibits the proliferation of NSCs as indicated by reduced number and size of neurospheres as well as by less BrdU-immunoreactive NSCs. Double immunofluorescence stainings of NSCs already being triggered to start with their differentiation showed that STZ primarily impairs the generation of new neurons, but not of astrocytes. For revealing mechanisms possibly involved in mediating STZ effects we analyzed expression levels of insulin/glucose system-related molecules such as the glucose transporter (GLUT) 1 and 3, the insulin receptor (IR) and the insulin-like growth factor (IGF) 1 receptor. Applying quantitative Real time-PCR (qRT-PCR) and immunofluorescence stainings we showed that STZ exerts its strongest effects on GLUT3 expression, as GLUT3 mRNA levels were found to be reduced in NSCs, and less GLUT3-immunoreactive NSCs as well as differentiating cells were detected after STZ treatment.

Sie ist pathologisch gekennzeichnet durch typische histologische fassbare zerebrale Ver{\"a}nderungen, Neurofibrillenb{\"u}ndel und amyloide Plaques, und einer ausgepr{\"a}gten, kortikal betonten Hirnatrophie gekennzeichnet. Zu den wichtigsten klinischen Leitsymptomen z{\"a}hlen Ged{\"a}chtnis- und Wortfindungsst{\"o}rungen sowie eine zeitliche und {\"o}rtliche Orientierungsst{\"o}rung. Es werden zwei Formen unterschieden: Die seltene famili{\"a}r autosomal- dominant vererbte Form mit fr{\"u}hem Beginn (Beginn vor dem 65. Lebensjahr) und die h{\"a}ufigste, die sporadische Form (Beginn nach dem 65. Lebensjahr), deren Ursache bis heute nicht vollst{\"a}ndig gekl{\"a}rt ist. Zu den wichtigsten Risikofaktoren der sAD z{\"a}hlt neben einer positiven Familienanamnese vor allem das Alter. Mittlerweile konnten immer mehr Studien auch ein deutlich hohes Risiko f{\"u}r AD besonders f{\"u}r Patienten mit unbehandelter Hypertonie belegen. Inzwischen mehren sich seit l{\"a}ngerer Zeit die Hinweise, dass ein wichtiger Zusammenhang zwischen der Entstehung von sAD und arterieller Hypertonie besteht. Ausgehend von der Hypothese, dass ein gest{\"o}rter zerebraler Insulinmetabolismus pathogenetisch bedeutsam f{\"u}r die Entwicklung einer sAD ist, werden in der Literatur zudem gehirnspezifische Ver{\"a}nderungen in der Insulin/ IR-Signalkaskade bei sAD beschrieben, die daraufhin deuten, dass es sich bei sAD um eine neuroendokrine St{\"o}rung handelt. Die vorliegende Studie besch{\"a}ftigt sich nun mit der Frage, ob ein Zusammenhang zwischen metabolischen Syndrom (wie arterielle Hypertonie und Insulinresistenz) und sAD nachweisbar ist und ob Hypertonie gehirnspezifische Ver{\"a}nderungen in der in der Insulin/ IR-Signalkaskade hervorrufen und somit auf diesen Weg pathophysiologischen Prozesse einer sAD f{\"o}rdern kann. Um diesen Zusammenhang zu {\"u}berpr{\"u}fen, wurden in dieser Studie erstmals Spontan Hypertensive Ratten (SHR) als experimentelles Modell ausgew{\"a}hlt. Dabei wurden Ver{\"a}nderungen bez{\"u}glich der Insulinrezeptorkonzentration sowie weiterer Bestandteile der Insulin/ IR-Signalkaskade in Gehirnen von drei Monate alten SHR und altersentsprechenden Kontrollratten mittels Enzym- Linked-Immuno-Sorbent Assays (ELISA) untersucht und miteinander verglichen. In dieser Studie war sowohl insgesamt als auch in allen untersuchten Regionen mit Ausnahme des Hypothalamus eine Erniedrigung der IRβ - Konzentration und damit ein deutlicher Mangel an IR β im Hirngewebe der SHR nachweisbar. Die Resultate des IR pTyr -fielen mit einer insgesamt tendenziellen Reduktion der IR pTyr - Konzentration der SHR {\"a}hnlich aus, wobei es innerhalb der Hirnregionen regionale Konzentrationsunterschiede gab. Bez{\"u}glich der aktivierten PKB ergab sich eine erniedrigte Gesamtkonzentration im Hirngewebe der SHR, allerdings war beim Gruppenvergleich in den einzelnen Hirnregionen nur im Hippokampus ein eindeutig signifikanter Konzentrationsunterschied zwischen beiden Gruppen zu verzeichnen. Die GSK 3β - Gesamtkonzentration der SHR zeigte sowohl insgesamt als auch in Vergleich zur Kontrollgruppe eine deutliche Erniedrigung. Im Gegensatz hierzu war die GSK- 3β pSer- Gesamtkonzentrationen der SHR insgesamt leicht erniedrigt, beim Vergleich der vier verschiedenen Hirnregionen zeigten sich jedoch keine signifikanten regionalen Konzentrationsunterschiede. Ein eindeutiger statistischer Zusammenhang zwischen den N{\"u}chtern- Blutzuckerspiegel, den Blutzuckerspiegel 30 Minuten nach Glukosetoleranztest und den jeweiligen K{\"o}rpergewicht der SHR und den Bestandteilen der Insulinrezeptorsignalkaskade konnte in der vorliegenden Studie nicht beobachtet werden. Zusammenfassend l{\"a}sst sich sagen, dass in den Gesamtproben der SHR signifikante St{\"o}rungen in der Signaltransduktion des Insulin-/ Insulinrezeptorsystem nachgewiesen werden konnten, die in der Literatur f{\"u}r sAD als typisch beschrieben werden. Dies untermauert wiederum die Hypothese, dass es sich bei der sAD um eine neuroendokrine St{\"o}rung mit gehirnspezifischen Fehlfunktionen in der Insulinrezeptorsignalkaskade handelt. Des Weiteren l{\"a}sst diese Arbeit den Schluss zu, dass es einen m{\"o}glichen Zusammenhang zwischen metabolischem Syndrom (wie arterielle Hypertonie und Insulinresistenz) und sAD gibt und Hypertonie ein bedeutsamer Risikofaktor f{\"u}r die Entwicklung einer sAD sein kann. Eine direkte Verbindung zwischen beiden Erkrankungen konnte jedoch nicht nachgewiesen werden. Weiterf{\"u}hrende und erg{\"a}nzende Untersuchungen mit zum Beispiel {\"a}lteren SHR und zus{\"a}tzlichen histopathologsichen Untersuchung werden jedoch notwendig sein, um diese Aussage zu best{\"a}tigen.  }, subject = {Morbus Alzheimer}, language = {de} } @article{BoltzeKleinschnitzReymannetal.2012, author = {Boltze, Johannes and Kleinschnitz, Christoph and Reymann, Klaus G. and Reiser, Georg and Wagner, Daniel-Christoph and Kranz, Alexander and Michalski, Dominik}, title = {Neurovascular pathophysiology in cerebral ischemia, dementia and the ageing brain - current trends in basic, translational and clinical research}, series = {Experimental \& Translational Stroke Medicine}, volume = {4}, journal = {Experimental \& Translational Stroke Medicine}, number = {14}, doi = {doi:10.1186/2040-7378-4-14}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-126679}, year = {2012}, abstract = {The 7th International Symposium on Neuroprotection and Neurorepair was held from May 2nd to May 5th, 2012 in Potsdam, Germany.
