Abstract

Exosome Signaling in Brain Development

Hollis Cline, Chairman of Neuroscience and Hahn Professor of Neuroscience, The Scripps Research Institute

Exosomes are thought to be secreted by all cells in the body and could to be involved in intercellular communication. I will describe experiments in which we tested whether neural exosomes regulate the development of neural circuits and whether exosome-mediated signaling may be aberrant in in vitro models of a neurodevelopmental disorder using human induced pluripotent stem cells (hiPSC) and in vivo rodent models. I will describe results of quantitative proteomic analysis of exosomes. Together our studies indicate that exosomes have the capacity to influence neuron and circuit development.
