New insights into sound coding in our ears

Sensory cells and neurons in the ear communicate by secreting neurotransmitter in response to sound stimuli. Scientists of the University Medical Center Göttingen, the Cluster of Excellence Multiscale Bioimaging, and the Max Planck Institute for Multidisciplinary Sciences describe new details of this process that regulates the release of neurotransmitters and

Generation of Pelizaeus-Merzbacher disease (PMD) mutant (PLP1-C33Y) in induced pluripotent stem cell (iPSC) by CRISPR/Cas9 genome editing

Authors Schreiber MK, Zafeiriou MP Journal Stem Cell Research Citation Stem Cell Res. 2023 Dec 7;74:103276. Abstract Genetic alterations in the PLP1 gene, i.e. point mutations and duplications, are associated with demyelinating disease Pelizaeus-Merzbacher. Here, we describe the generation of a human iPSC line harboring a PLP1 variant in codon
