BACKGROUND Glyoxalases (Glo1 and Glo2) are involved in the glycolytic pathway by detoxifying the reactive methylglyoxal (MGO) into D-lactate in a two-step reaction using glutathione (GSH) as cofactor. Inhibitors of glyoxalases are considered as anti-inflammatory and anti-carcinogenic agents. The recent finding that various polyphenols modulate Glo1 activity(More)
The LDL receptor-related protein/alpha 2-macroglobulin receptor (LRP1/A2MR) is a multifunctional cell-surface glycoprotein that endocytoses several structurally and functionally distinct ligands. In clinical studies different genomic variants of the LRP1/A2MR and its role in the development of degenerative diseases like atherosclerosis or Alzheimer's(More)
Mast cells (MCs) are considered major players in IgE-mediated allergic responses, but have also recently been recognized as active participants in innate as well as specific immune responses. Recent work provided evidence that MCs are able to activate B and T lymphocytes through the release of vesicles called exosomes. Here we demonstrate that exosomes,(More)
Overproduction of transforming growth factor (TGF)-beta 1 messenger RNA is of fundamental importance in the pathogenesis of diabetic nephropathy. In vitro studies have recently shown that the serine protease trypsin diminishes the enhanced TGF-beta 1-expression induced by advanced glycation end products. Moreover, proteolytic enzymes may accelerate the(More)
One unexpected feature of the human genome is the high structural variability across individuals. Frequently, large regions of the genome show structural polymorphisms and many vary in their abundance. However, accurate methods for the characterization and typing of such copy number variations (CNV) are needed. The defensin cluster at the human region(More)
With all the incredible progress in scientific research over the past two decades, the trigger of the majority of autoimmune disorders remains largely elusive. Research on the biology of T helper type 17 (T(H)17) cells over the last decade not only clarified previous observations of immune regulations and disease manifestations, but also provided(More)
Immobilized metal ions were used for the affinity extraction of proteins in aqueous two-phase systems composed of polyethylene glycol (PEG) and dextran or PEG and salt. Soluble chelating polymers were prepared by covalent attachment of metal-chelating groups to PEG. The effect on the partitioning of proteins of such chelating PEG derivatives coordinated(More)
We compared, using a combination of different immunological methods and by competitive PCR, the expression of the alpha2-macroglobulin receptor/low-density lipoprotein receptor-related protein (alpha2-M-R/LRP) in human keratinocytes and fibroblasts. This receptor has previously been found in skin only in dermal cells associated with fibroblasts and(More)
Monoclonal antibodies against the human proteinase inhibitor, alpha 2 macroglobulin, have been produced by immunizing BALB/c mice with alpha 2 macroglobulin reacted with methylamine. Two antibodies have been characterized in detail with respect to their binding to native alpha 2 macroglobulin and to different derivatives of the inhibitor. The antibody(More)
Insulin-like growth factor-I (IGF-I) and alpha 2-macroglobulin (alpha 2-M) are believed to be involved in the development of germ cells. IGF-I is mainly controlled by concentrations of human growth hormone (HGH), influences cell proliferation and differentiation and its action is mediated by insulin-like growth factor-binding proteins (IGFBP), placental(More)
