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 ...
Nemertean nervous system: a comparative analysis
(2012-07-13)
Most described nemerteans are marine benthic hunters. Thus, they possess a well developed nervous system. Basically, the nervous system comprises a four lobed brain, two main lateral medullary cords, some minor nerves, ...
Regulation of the dsr operon and function of the proteins DsrR and DsrS in the purple sulfur bacterium Allochromatium vinosum
(2012-05-25)
This work represents the first in depth investigation of the dsr gene expression in a phototrophic sulfur-oxidizing organism. Although over the last decade some observations were made concerning regulation a more detailed ...
Analyses of Adhesion Topography and Fluctuations in Bio-Membranes by Advanced Optical Microscopy
(2012-05-21)
The cell membrane not only mechanically separates the interior of the cell from the exterior environment but is also an active organelle involved in a host of functions like maintaining osmotic balance, aiding in ...
DNA barcoding & multi-isotopic fingerprinting: a novel forensic toolbox for the rapid identification of illegal trade in endangered wildlife species
(2012-05-08)
Over-exploitation through illegal wildlife trade is a major threat to a wide range of endangered mammal species around the world, particularly to the Felidae. Illegal trade in wild cats is often in the form of bones, meat, ...
Kontrolle der lateralen Organisation von Membranproteinen
(2012-06-12)
In den letzten Jahrzehnten wurde bei Untersuchungen an Zellmembranen deutlich, dass viele Membranproteine nicht, wie ursprünglich angenommen, homogen verteilt sind, sondern in Mikrodomänen organisiert vorkommen. Die ...
Role of the VAsodilator-Stimulated Phosphoprotein (VASP) in brown fat cell differentiation and function
(2012-05-23)
Obesity and associated metabolic disorders result from an imbalance between energy intake and expenditure. In contrast to white fat, which is the major site of energy storage in the body, brown adipose tissue (BAT) is ...
Der Einfluss des Polymorphismus auf die Ausbildung von HLA-DQ-Peptidrezeptoren
(2011-04-12)
Klasse-II-Moleküle werden durch Gene des Haupthistokompatibilitätskomplexes (HLA) kodiert und dienen der Antigenpräsentation. Ein Klasse-II-Molekül besteht aus einer Alpha- und einer Beta-Untereinheit, die sich zu einem ...
Dendritic integration in hippocampal dentate gyrus granule cells
(2011-04-20)
Hippocampal granule cells are critical relay stations to transfer spatial information from the entorhinal cortex into the hippocampus proper. Therefore, the integrative properties of the small-caliber granule cell dendrites ...
Studien zur Funktion der Koaktivatoren ZIP-Kinase, AATF und TSG101 in der Androgenrezeptor-vermittelten Transkription
(2011-03-22)
In unserer Arbeitsgruppe wurden mit der murinen ZIPK, dem Transkriptionsfaktor AATF und dem Ubiquitin-Bindeprotein TSG101 neue Koaktivatoren der AR-abhängigen Transkription identifiziert, deren funktionelle Kooperation in ...
