Loss of Inhibitory CD33 Signaling Results in Increased Microglial Activation
(2021-06-23)
CD33 is expressed on immune cells of myeloid origin, such as macrophages and microglia. Upon activation, CD33 recruits and activates protein tyrosine phosphatases, which results in attenuation of the activatory signaling ...
Design, assembly, and operation of a self-regulating DNA rotaxane linear actuator
(2022-04-07)
DNA is not only the carrier of genetic information but also an excellent bottom-up material for constructing nanostructures due to its high degree of programmability. Interlocked DNA nanostructures have a potential use as ...
Low Endotoxin Recovery: Wiederfindung und pyrogene Aktivität von Endotoxinen in pharmazeutischen Produkten
(2021-08-06)
Eine zuverlässige Überwachung bakterieller Kontaminationen ist entscheidend für die Herstellung und Sicherheit biopharmazeutischer Produkte. Die mikrobielle Sicherheit wird in der Regel (zusätzlich zu Sterilitätstests und ...
Functional impact of Kir4.1 channels in hippocampal NG2 glia on neuronal plasticity and behavior
(2020-08-25)
NG2 glia represents the 4th type of CNS glial cells. In white matter, most of them differentiate into myelinating oligodendrocytes but in grey matter a majority retains their NG2 phenotype throughout life. Intriguingly, ...
Investigation of the procoagulant role of labile heme under hemolytic conditions
(2021-07-19)
Severe intravascular hemolysis leads to the excessive release of labile heme into the vascular compartment, thereby overwhelming the heme-binding capacity of the protective heme- scavenging system. As a consequence, labile ...
Design and Synthesis of Covalent Peptidomimetic Inhibitors for Human Cysteine Cathepsins
(2020-02-07)
The present thesis elucidates the development of (i) a series of small molecule inhibitors reacting in a covalent-irreversible manner with the targeted proteases and (ii) a fluorescently labeled activity-based probe as a ......
Mechanisms of epileptogenesis in animal models of developmental brain lesions
(2021-11-05)
Developmental brain lesions, including glioneuronal tumors (GNT) and malformations of cortical development (MCD), are among the most common causes for pharmaco-resistant epilepsy. Despite substantial differences, their ...
Compartmentalisation of cAMP in Brown Adipocytes
(2022-02-14)
The second messenger, 3',5'-cyclic adenosine monophosphate (cAMP) plays an important role in governing the function and differentiation of brown adipocytes. Upon the stimulation of Gs-coupled G protein-coupled ...
Vorkommen Antibiotika-resistenter Bakterien in der aquatischen Umwelt: Zusammenhänge zu dem Vorkommen antibiotisch wirkender Substanzen
(2022-01-05)
Ein Anstieg der Resistenzen bei gleichzeitiger Stagnation hinsichtlich der Ent-wicklung neuer Antibiotika ist vor allem für Infektionen mit Gram-negativen Bakte-rien kritisch. Die WHO spezifizierte bereits 2014 ...
γ-Hydroxybuttersäure (GHB)-Analytik zum Zweck der Verlängerung des Nachweisfensters einer exogenen GHB-Gabe sowie der Verbesserung der postmortalen Befundinterpretation
(2022-06-17)
Der endogene Neurotransmitter γ-Hydroxybuttersäure (GHB) stellt Gutachter in forensisch-toxikologischen Kontexten regelmäßig vor große Herausforderungen. Im Zusammenhang mit ungeklärten Todesfällen, Suiziden oder ...
