The development, progression, and recurrence of autoimmune diseases are frequently driven by a group of participatory autoantigens. We identified and characterized novel autoantigens by analyzing the autoantibody binding pattern from horses affected by spontaneous equine recurrent uveitis to the retinal proteome. Cellular retinaldehyde-binding protein(More)
Cultured primary retinal Müller glia cells (RMG), a glia cell spanning the entire neuroretina, have recently gained increased attention, especially with respect to their presumed in vivo role in supporting photoreceptor function and survival. Cultured RMG cells, however, are at risk to lose much of their in vivo features. To determine the conditions of(More)
PURPOSE Dedifferentiation of retinal pigment epithelial (RPE) cells is a crucial event in the pathogenesis of proliferative vitreoretinopathy (PVR). This study was designed to improve the understanding of RPE cell dedifferentiation in vitro. The protein expression pattern of native differentiated RPE cells was compared with that of cultured, thereby(More)
The kinetics and efficiency of decoding of the UGA of a bacterial selenoprotein mRNA with selenocysteine has been studied in vivo. A gst-lacZ fusion, with the fdhF SECIS element ligated between the two fusion partners, gave an efficiency of read-through of 4-5%; overproduction of the selenocysteine insertion machinery increased it to 7-10%. This low(More)
Glial cell line-derived neurotrophic factor (GDNF) protects dopaminergic neurones against toxic and physical damage. In addition, GDNF promotes differentiation and structural integrity of dopaminergic neurones. Here we show that GDNF can support the function of primary dopaminergic neurones by triggering activation of GTP-cyclohydrolase I (GTPCH I), a key(More)
BACKGROUND Expression and purification of correctly folded proteins typically require screening of different parameters such as protein variants, solubility enhancing tags or expression hosts. Parallel vector series that cover all variations are available, but not without compromise. We have established a fast, efficient and absolutely background free(More)
Retinitis pigmentosa comprises a heterogeneous group of incurable progressive blinding diseases with unknown pathogenic mechanisms. The retinal degeneration 1 (rd1) mouse is a retinitis pigmentosa model that carries a mutation in a rod photoreceptor-specific phosphodiesterase gene, leading to rapid degeneration of these cells. Elucidation of the molecular(More)
A proposal for the introduction of the Minimal Information (MI) platform dedicated to the acquisition and annotation of data concerning recombinant proteins (Minimal Information for Protein Functionality Evaluation – MIPFE) was recently published [1] and discussed at the 5 th Recombinant Protein Production Conference (Alghero 2008) and the 2009 PEP Talk(More)
Wave-mixed bioreactors have increasingly replaced stainless steel stirred tank reactors in seed inoculum productions and mammalian cell-based process developments. Pre-sterilized, single-use plastic bags are used for cultivation, eliminating the risk of cross-contamination and cleaning procedures. However, these advantages come with high consumable costs(More)
Burkitt Lymphoma (BL) cells are highly sensitive to suboptimal growth conditions and undergo apoptosis when seeded at low cell density or reduced serum concentration. Irradiated fibroblasts or a mix of pruvate, alpha-thioglycerol, and bathocuproine disulfonate can protect BL cells from apoptosis induced by lowering cell density or serum concentration by(More)
