Epidermolysis bullosa refers to a group of genodermatoses that affects the integrity of epithelial layers, phenotypically resulting in severe skin blistering. Dowling-Meara, the major subtype of epidermolysis bullosa simplex, is inherited in an autosomal dominant manner and can be caused by mutations in either the keratin-5 (K5) or the keratin-14 (K14)(More)
The major challenge to a successful gene therapy of autosomal dominant genetic diseases is a highly efficient and specific knock-down or repair of the disease-causing allele. In epidermolysis bullosa simplex-type Dowling-Meara (EBS-DM), a single amino acid exchange in exon 1 of the keratin 14 gene (K14) triggers a severe skin phenotype, characterized by(More)
BACKGROUND The growing number of novel candidate molecules for the treatment of allergic diseases imposed a dramatic increase in the demand for animal experiments to select immunogenic vaccines, a pre-requisite for efficacy. Because no in vitro methods to predict the immunogenicity of a protein are currently available, we developed an in vitro assay that(More)
Trans-splicing is a powerful approach to reprogram the genome. It can be used to replace 5', 3' or internal exons. The latter approach has been characterized by low efficiency, as the requirements to promote internal trans-splicing are largely uncharacterized. The trans-splicing process is induced by engineered 'RNA trans-splicing molecules' (RTMs), which(More)
Spliceosome-mediated RNA trans-splicing has become an emergent tool for the repair of mutated pre-mRNAs in the treatment of genetic diseases. RNA trans-splicing molecules (RTMs) are designed to induce a specific trans-splicing reaction via a binding domain for a respective target pre-mRNA region. A previously established reporter-based screening system(More)
The activation-induced cytidine deaminase (AID) mediates somatic hypermutation and class switch recombination of the Ig genes by directly deaminating cytosines to uracils. As AID causes a substantial amount of off-target mutations, its activity has been associated with lymphomagenesis and clonal evolution of B-cell malignancies. Although it has been shown(More)
The presence of neural stem/progenitor cells (NSPCs) in specific areas of the central nervous system (CNS) supports tissue maintenance as well as regeneration. The subependymal zone (SEZ), located at the lateral ventricle's wall, represents a niche for NSPCs and in response to stroke or demyelination becomes activated with progenitors migrating towards the(More)
IL-31 is a T cell-derived cytokine that signals via a heterodimeric receptor composed of IL-31Rα and oncostatin M receptor β. Although several studies have aimed to investigate IL-31-mediated effects, the biological functions of this cytokine are currently not well understood. IL-31 expression correlates with the expression of IL-4 and IL-13 and is(More)
RNA trans-splicing has become a versatile tool in the gene therapy of monogenetic diseases. This technique is especially valuable for the correction of mutations in large genes such as COL7A1, which underlie the dystrophic subtype of the skin blistering disease epidermolysis bullosa. Over 800 mutations spanning the entire length of the COL7A1 gene have been(More)
