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 ...
Zelluläre und molekulare Mechanismen der Entzündungsauflösung im postoperativen Ileus
(2015-12-23)
Nach postoperativen Eingriffen kommt es regelhaft zu einer Darmmotilitätsstörung, dem sogenannte postoperativen Ileus (POI). Die Dauer und Intensität des POI werden von einer komplexen Entzündungsreaktion in der Muscularis ...
Ribosome profiling of selenoproteins in vivo reveals consequences of pathogenic Secisbp2 missense mutations: The establishment of translating ribosome affinity purification
(2020-11-04)
Recoding of in-frame UGA/Seccodon in selenoproteins requires a complex translational machinery. The core of this event is the interaction between selenocysteine insertion sequence (SECIS element) in the 3’UTR of ...
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 ...
Structural and functional principles of long-range connectivity in the rat vibrissal system
(2020-11-05)
Pyramidal tract neurons (PTs) represent the major output cell type of the mammalian neocortex. Integrating feedforward thalamo-cortical (TC) and recurrent intracortical (IC) inputs with those from top down cortical-cortical ...
Search for exosomes in NG2-glial cells
(2022-02-17)
NG2-glial cells is an abundant and widely distributed subtype of glia, featuring properties not typically associated with mature glial cells, such as the ability to receive synaptic input from neurons, or adult proliferation. ...
Proteomische Funktionsanalyse humanbiologischer Systeme mittels chemisch modifizierter Proteine
(2016-04-18)
Das humane Proteom unterliegt gegenüber dem eher statischen Genom einem kontinuierlichen Auf- und Abbau. Diese Dynamik zeigt sich durch ein mehrschichtiges Muster an Protein-Protein Interaktionen.
Im ersten Teil ...

The role of the Hippo pathway in etiology and progression of pancreato-biliary tumors and clear cell renal cell carcinoma
(2016-01-21)
In the quest for the discovery of novel targets for cancer therapy, aberrantly reactivated embryonic signaling pathways have proven to be a rich mine and recent years have seen the introduction of the hedgehog-inhibitor ...
Neuroprotective Effects of Polysialic Acid and SIGLEC-11 in Activated Phagocytic Cells
(2016-03-30)
SIGLEC-11 is an inhibitory receptor expressed on microglial cells and macrophages and can recognize α 2→8 linked Sias structures. The surface of neuron is decorated by different lengths of polySias. PolySia-SIGLEC-11 ...
