title: Signaling survival: how axons rescue their glia.
abstract: The trophic theory of cell survival hypothesizes that cell number is regulated by survival signals generated by other cells. Work published in this issue of Developmental Cell confirms that neurons can provide trophic support for glia in Drosophila, and fills in important molecular details of this interaction.
