Autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED) is a monogenic autoimmune disease caused by biallelic genetic variants in the AIRE gene, encoding autoimmune regulator protein.
As in other muco-obstructive diseases, the airways in cystic fibrosis (CF) are characterized by goblet cell and glandular hyperplasia, with overproduction of mucins MUC5 and MUC5AC, resulting in viscous mucus, respiratory blockade and recurrent infections and inflammation.
The development of cystic fibrosis transmembrane conductance regulator (CFTR) modulators has significantly improved the therapeutic scenario for CF patients in the past decade. However, around 10% of patients harboring nonsense and splice-site mutations are nonresponsive to CFTR modulators.
Scientists from 4D Molecular Therapeutics Inc. disclosed the preclinical evaluation of 4D-710, an aerosolized gene therapy that consists of a lung-specific evolved A101 capsid vector, the promoter CMV173 and the transgene codon-optimized human CFTRΔR.
How do exercise and insulin collaborate in metabolism? The European Association for the Study of Diabetes (EASD) and the Novo Nordisk Foundation recognized the work of Juleen Zierath in this topic with the Diabetes Prize for Excellence at their recent annual meeting.

Multiple sulfatase deficiency (MSD) is a rare lysosomal storage disorder caused by pathogenic variants in the sulfatase modifying factor 1 gene (SUMF1). Researchers from the University of Pennsylvania described the efficacy of hematopoietic stem cell transplantation (HSCT) with ex vivo SUMF1 lentiviral gene therapy (SUMF1-GT) in a mouse model of MSD.
CTNNB1 syndrome is a neurodevelopmental disorder characterized by intellectual disability, global developmental delay, microcephaly and motor disabilities, among others, caused by pathogenic loss-of-function variants in the CTNNB1 gene, which encodes β-catenin. This syndrome has no treatment option, with only supportive care available. To address this unmet medical need, researchers from the Broad Institute and Tufts University School of Biomedical Sciences have developed a Ctnnb1 germline heterozygote murine model that mimics the human CTNNB1 syndrome.
Shwachman-Diamond syndrome is an inherited bone marrow failure syndrome characterized by exocrine pancreatic insufficiency, cytopenia, growth restriction and skeletal abnormalities, and for which primary treatment is allogeneic hematopoietic stem cell transplantation, which is associated with significant toxicity.
Mutations in the GNAO1 gene are tied to neurological disorders characterized by movement abnormalities and developmental delay. GNAO1 encodes the protein guanine nucleotide-binding protein G(o) subunit α, which is highly expressed in the brain. Among the mutations, R209H results in dystonia, choreoathetosis and developmental delay without seizures.
