Approved antiviral medicine shows promise in RDEB mouse model

Daclatasvir, an approved antiviral medicine, safely reduced the signs and symptoms of recessive dystrophic epidermolysis bullosa (RDEB) in a mouse model, a drug repurposing study revealed. Data showed that the antiviral, a treatment for the hepatitis C virus (HCV) sold under the brand name Daklinza, extended RDEB mouse survival…

CRISPR Gene Editing Restores Collagen Production in Mice

Getting gene editing based on CRISPR, a kind of molecular scissors, delivered directly into cells may help restore the production of type VII collagen, the protein that’s missing in patients with dystrophic epidermolysis bullosa (DEB), a mouse study found. If the findings hold in humans, they “would allow the…

Hsp70 Autoantibodies Elevated in EBA, May Contribute to Disease

Self-reactive antibodies against the stress-induced heat shock protein 70 (Hsp70) were higher in the blood of patients with epidermolysis bullosa acquisita (EBA), a study found. In a corresponding mouse model, the researchers observed the autoantibodies contributed to a worse disease course, likely through the mediation of inflammatory pathways. “This…

Decorin Extends Survival, Eases Skin Fibrosis in Mouse Model of RDEB

Increased levels of a protein called decorin extended survival, reduced skin fibrosis (scarring) and delayed the development of paw deformities and other key recessive dystrophic epidermolysis bullosa (RDEB) manifestations in a mouse model. The study, “Decorin counteracts disease progression in mice with recessive dystrophic epidermolysis bullosa,”…
