Transthyretin (TTR) distributes thyroxine in the cerebrospinal fluid of mammals. Choroid plexus epithelial cells produce and secrete TTR, and were long recognized as the only CNS source of TTR. However, research over the last years has reported neuronal-specific expression as well, but without a clear function. Recently, we found Ttr transcripts in cells of the adult mouse subventricular zone (SVZ), the largest neural stem cell (NSC) region, but the protein was undetectable. W...

Thyroid hormones (THs) play a crucial role orchestrating neurodevelopment, but also regulate adult brain function. Recently, the potent effects that THs exert in adult neurogenic niches have started to be uncovered in rodents. These include an important role in the modulation of progenitor generation, especially controlling whether a neural stem cell (NSC) determines to become a neuronal or an oligodendroglial progenitor in the adult subventricular zone (SVZ), the largest NSC ...
