We identified increased expression and redistribution of the intracellular protein 60-kDa human heat shock protein (hHSP60) (HSPD1) to the cell surface in human endothelial cells subjected to classical atherosclerosis risk factors and subsequent immunologic cross-reactivity against this highly conserved molecule, as key events occurring early in the process(More)
With several multivariate statistical methods a classification of dioxin data has been tried. As a main result one significant source of dioxin in the river Elbe, in the harbour of Hamburg as well as in soils of the flooding areas of the river Elbe could be identified: the dioxin contaminated region Bitterfeld. Our statistical results indicate that the(More)
Owing to its unique host cell-dependent development cycle, Chlamydia pneumoniae occupies an intracellular niche that enables the bacterium to survive and to multiply, secluded from both the extracellular and the cytoplasmic environments. Within its separate chlamydial inclusion, it is able to genetically switch between a replicative and a persisting(More)
Since its description in 1986, Chlamydia pneumoniae has remained one of the most enigmatic pathogens. This intracellular bacterium is highly seroprevalent, but rarely recovered from cell culture, it can genetically switch between a proliferative and a nonreplicative state and has been linked to a vast number of chronic diseases, most notably to(More)
Mycoplasma contamination is a frequent problem in chlamydial cell culture. After obtaining contradictory contamination results, we compared three commercial PCR kits for mycoplasma detection. One kit signaled contamination in mycoplasma-free Chlamydia pneumoniae cultures. Sequencing of cloned PCR products revealed primer homology with the chlamydial genome(More)
Endothelin-1 (ET-1) is a vasoactive peptide that modifies vascular function via the G-protein coupled transmembrane receptors, Endothelin-A receptor (ETAR) and Endothelin-B receptor (ETBR). Dysregulation of the ET-1 axis plays a role in atherosclerotic development as it triggers cell proliferation, inflammation, and vasoconstriction. The respiratory(More)
Due to its dependence on intracellular development Chlamydia pneumoniae has developed numerous strategies to create an adequate environment within its host cells ensuring both chlamydial reproduction and target cell survival. The bacterium that has been related to atherogenesis due to its presence in vascular tissue is able to enter a persistent state of(More)
Chlamydia pneumoniae is a universal pathogen that has been indicated to play a part in the development of asthma, atherosclerosis and lung cancer. The complete eradication of this intracellular bacterium is in practice impossible with the antibiotics that are currently in use and studies on new antichlamydial compounds is challenging because Chlamydia(More)
