Over the past decade an intriguing connection between asymmetric cell division, stem cells and tumorigenesis has emerged… Expand Summary It is firmly established that interactions between neurons and glia are fundamental across species for the correct… Expand Axon guidance is a key process during nervous system development and regeneration. One of the best established paradigms to study… Expand Analysis of the function of the fly ZO-1 homologue Polychaetoid shows that it is not essential for junctional assembly or… Expand Vertebrates and insects alike use glial cells as intermediate targets to guide growing axons. Similar to vertebrate… Expand Cadherin-based adherens junctions (AJs) mediate cell adhesion and regulate cell shape change. The nectin–afadin complex also… Expand Asymmetric cell division is a conserved mechanism to generate cellular diversity during animal development and a key process in… Expand Over the past few years, it has become increasingly apparent that signal transduction pathways are not merely linear cascades… Expand Rap1 belongs to the highly conserved Ras subfamily of small GTPases. In Drosophila, Rap1 plays a critical role in many different… Expand Cone cells are lens-secreting cells in ommatidia, the unit eyes that compose the compound eye of Drosophila. Each ommatidium… Expand
