Ambigols A-C and tjipanazole D: bioinformatic analysis of their putative biosynthetic gene clusters
(2011-08-04)
Cyanobacteria are Gram negative, photoautotrophic bacteria, which are distinguished by an impressive array of chemically diverse natural products. The here investigated cyanobacterial strain of Fischerella ambigua was shown ...
Development of pharmacological modulators for the orphan G protein-coupled receptor GPR17 and their application for the investigation of molecular signal transduction pathways
(2011-11-29)
In order to discover a set of tools suitable to be employed in its in vitro characterization, the recently deorphanized G protein coupled receptor GPR17 was investigated by using different classical second messenger assays ...
Evaluation of Wolbachia depletion after antibiotic treatment using real-time PCR in Onchocerciasis and Lymphatic Filariasis, and analysis of genetic associations in Lymphatic Filariasis
(2011-11-15)
Two of the major filarial infections, onchocerciasis and LF, affect > 150 million people. Currently, control programs use yearly mass application of drugs that mainly kill microfilaria (Mf) with the aim to prevent uptake ...
Lipid-basierte Transfektionssysteme für die posttranskriptionelle Expressionshemmung von endothelialem VCAM-1 als potentiell antiinflammatorischer Therapieansatz
(2011-08-04)
Bei der Entstehung von Entzündungen ist das vaskuläre Endothel von zentraler Bedeutung: Stimuliert durch Entzündungsmediatoren exprimieren Endothelzellen eine Reihe proinflammatorischer Adhäsionsrezeptoren, die eine Anhaftung ...
Functional characterization of the 5-oxo-ETE receptor OXE-R and identification of the first small molecule antagonist with a novel mechanism of ligand bias
(2011-10-21)
The lipid mediator 5-oxo-ETE (OXE) is a metabolite of the 5-lipoxygenase pathway and acts as a potent chemoattractant on eosinophils and neutrophils. OXE-induced effects are mediated via the Gi coupled 5-oxo-ETE ...
Mechanismen der hepatischen Immunregulation
(2011-10-21)
Die Leber vermittelt als immunmodulatorisches Organ einerseits eine periphere Immun-Toleranz, muss aber andererseits bei einer Infektion gleichzeitig die Induktion einer Immunantwort zulassen, die in der Lage ist, infizierte ......
Development of Selective Nitrile Inhibitors and ‘Activity-Based’ Probes For Human Cathepsins K and S
(2012-06-20)
Cysteine cathepsins show a high degree of similarity and play a significant role in many (patho)physiological processes such as bone remodeling, antigen presentation, osteoporosis, autoimmune disorders, and cancer. Therefore, ...
Beteiligung ATP-abhängiger Transportprozesse an der Resistenz gegenüber Platinkomplexen
(2012-08-10)
Eine reduzierte zelluläre Kumulation von Cisplatin ist ein häufig beobachteter Mechanismus der Platinresistenz. Es wird vermutet, dass neben der passiven Diffusion auch verschiedene energieabhängige Proteine, welche die ...
Experimental and numerical studies on solute transport in unsaturated heterogeneous porous media under evaporation conditions
(2012-08-31)
Groundwater level rise, root water uptake, or evaporation induces local upward water and solute fluxes in soils, causing soil salinization and rise of contaminants to the soil surface, and influencing the migration of ...
Characterization of the role of Hydroxyprostaglandin dehydrogenase 15-(NAD) in human regulatory T cells
(2012-06-14)
The focus of the present study was the characterization of the hydroxyprostaglandin dehydrogenase 15-(NAD) (HPGD) in CD4+CD25+ regulatory T cells (Treg) concerning its regulation and role for the development and suppressive ...
