BACKGROUND Several fungal species are known to cause severe respiratory and cutaneous allergic diseases. Extracts from several allergenic fungi are used for in vivo and in vitro tests, as standard preparations are still not available. OBJECTIVE The aims are to define the pattern of in vivo and in vitro IgE reactivity to fungal species in an allergic(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)
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)
Blistering in epidermolysis bullosa simplex type Dowling-Meara (EBS-DM) is associated with an inflammatory phenotype, which can be disrupted by diacerein in vitro. In this pilot study we hypothesized, that a topical formulation of diacerein 1% reduces blistering. Five patients initially applied diacerein underneath both armpits. Then, each participant(More)
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 efficient treatment of hereditary disorders, especially of those caused by dominant-negative mutations still remains an obstacle to be overcome. Allele specificity is a critical aspect that must be addressed by silencing therapies such as small interfering RNA, which has the potential risk of also reducing expression of the normal allele. To overcome(More)
Spliceosome-mediated RNA trans-splicing (SMaRT) is an RNA-based technology to reprogram genes for diagnostic and therapeutic purposes. For the correction of genetic diseases, SMaRT offers several advantages over traditional gene-replacement strategies. SMaRT protocols have recently been used for in vitro phenotypic correction of a variety of genetic(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)
In the treatment of genetic disorders, repairing defective pre-mRNAs by RNA trans-splicing has become an emerging alternative to conventional gene therapy. Previous studies have made clear that the design of the binding domains of the corrective RNA trans-splicing molecules (RTMs) is crucial for their optimal functionality. We established a reporter-based(More)
Keratin filaments form obligatory heterodimers consisting of one type I and one type II keratin that build the intermediate filaments. In keratinocytes, type II keratin 6 (K6) interacts with type I keratin 16 (K16). We previously showed that the intermediate filament protein K16 is up-regulated in aged human skin. Here, we report that there is an obvious(More)
