UHBrain seminar by Professor Petra Wahle

Activity-dependent growth of dendrites and axons of cortical interneurons

Speaker. Professor Petra Wahle
( Developmental Neurobiology, Faculty of Biology and Biotechnology, Ruhr University, Bochum, Germany).
Host: Sari Lauri

Abstract: We have studied the role of ionotropic receptors for dendritic growth of neocortical interneurons (our preferred prey) and pyramidal cells (the "bycatch", but also delivering stories) over the past years, and I'll report some recent findings including work on GPCR-coupled receptors. Further, we recently turned to interneuronal axons, many of which emerge actually from dendrites, not somata. These privileged dendrites have been termed "axon-carrying dendrites, AcD". When depolarized they can fire the axon without somatic integration avoiding somatic inhibition. The proportion of AcD cells varies between cell type, cortical layers, and mammalian species. We started to look for a developmental influence of such AcDs and the axon it carries. The picture emerging is that both are in a mutual growth-promoting relationship, and  - up to debate -  our recent findings argue for a role of GluN2D-containing NMDA receptors.  Finally, something to muse on: what about cells with more than one axon?
