Abstract

Shc family of adaptor molecules has been demonstrated to play an important role during the transition from proliferating neural stem cells to postmitotic neurons. Previous studies from our group demonstrated a progressive decrease of ShcA levels occurring in coincidence with the end of embryonic neurogenesis and neuronal maturation, being ShcB and ShcC the major Shc molecules expressed in the mature brain. A growing body of evidence indicates that ShcB and ShcC are neuronal specific molecules exerting important roles in neuronal survival and phenotypic stability thus becoming potential attracting target molecules for development of drugs for interfering with brain demises. Here, we examine the expression pattern of ShcB and ShcC in neuronal populations composing the adult central and peripheral nervous system, in order to better elucidate their roles in vivo. We found a heterogeneous and peculiar presence and subcellular localization of ShcB and ShcC in specific neuronal populations, enlightening a potential specific requirement of these two molecules in the survival/maintenance of defined neuronal subtypes.
