The Phenomenon of Functional Retention of Incorporated Chloroplasts in Sea Slugs (Sacoglossa, Heterobranchia, Mollusca) and Evolutionary Adaptations: Aspects of Photobiology, Cell Biology, Ecology and Behavior
(2020-01-30)
The phenomenon of retention of functional chloroplasts from their food algae in sacoglossan sea slugs - also called kleptoplasty - is a challenge for research, still leaving many questions unsolved, e. g. concerning ......
Characterisation of Extracellular Vesicles Released upon NLRP3 Activation and Their Impact on Bystander Cells
(2020-02-17)
Inflammasomes are cytosolic multi-protein complexes that assemble upon detection of danger signals of infectious or sterile origin. Activation of the NOD-like receptor NLRP3 results in activation of caspase-1, which ...
Investigating the molecular basis of human NLRP1 inflammasome activation
(2020-03-10)
Cytosolic sensor proteins like NLRP1 (NOD-like receptor containing a pyrin domain 1) play a fundamental role in mediating innate immunity. Upon activation they form signalling hubs that recruit the adaptor protein ASC ...
Impact of chronic liver inflammation on adaptive immune responses to viral infection
(2020-03-11)
A common complication in patients suffering from chronic liver inflammation and fibrosis is the enhanced susceptibility to viral infections and weak responses to vaccination, which are associated with significant co-morbidities. ...
Neuroinflammation, microglia and the cell biology of Alzheimer's Disease
(2020-04-08)
The pathology of Alzheimer’s disease (AD) is characterised by progressive accumulation of misfolded proteins, which form senile plaques and neurofibrillary tangles, and chronic inflammation in the brain associated with ...
Immune defense mechanisms against Legionella longbeachae
(2020-01-30)
The pulmonary epithelial barrier is the first line of defense against pathogens invading the lungs. If those are able to overcome this first barrier, myeloid cells of the innate immune system are instrumental for the ......
Proteomic identification of posttranslational modifications: cAMP-induced changes of phosphorylation and investigation of novel approaches detecting posttranslational modifications at lysine and arginine residues
(2020-04-22)
Cyclic adenosine monophosphate (cAMP) is an important second messenger which can be generated in response to signals binding to stimulatory G-protein coupled receptors. Inside the cell, protein kinase A is a well-known ...
Impact of UGT1A polymorphisms on inflammation and fibrogenesis in a humanized transgenic mouse model
(2020-07-07)
Fibrogenesis represents a highly dynamic scarring response of the liver resulting from different causes of hepatic injury. A key process capable of activating a broad array of profibrogenic pathways is oxidative stress. ...
Science und Fiction - Entwicklung und Evaluation eines Konzepts zum interesseförderlichen Einsatz von kreativen Schreibwerkstätten im Biologieunterricht
(2020-08-07)
Interesse wird als wichtige Voraussetzung für die Dynamik und Qualität von Bildungsprozessen angesehen und gilt als einer der Vorläufer einer generellen, selbstbestimmten Lernmotivation. Im Mittelpunkt dieser vorrangig ...
Stereoselektive Polyolsynthese zur Untersuchung von Wasserstoffbrückenbindungen mittels IR-Spektroskopie
(2020-12-11)
Um die anomalen Eigenschaften des Wassers gänzlich zu verstehen, ist die intensive Untersuchung von Wasserstoffbrücken erforderlich. IR-spektroskopische Messungen vernetzter Flüssigkeiten liefern dabei eine Fülle an ...
