- Developmental Neurobiology.
Directional movement of the growth cone, the terminal extension of the outgrowing axon, is a complex signal transduction process dictated by a series of attractive and repulsive guidance cues lining the path. Cell surface receptors detect these cues and initiate intracellular signaling events to dictate axon outgrowth and steering. We seek to understand this signaling process by studying an axon’s decision to cross or not to cross the midline of an embryo using the molecular, cellular and genetic toolbox of Drosophila.
The ventral cord of a Drosophila embryo is a ladder-like scaffold of axons with an anterior (AP) and posterior (PC) commissure joining longitudinal connectives (LC) on each side of the midline. Netrins are chemoattractive cues guiding axons across the midline. Netrins are detected by Frazzled, which in turn activates several intracellular signaling pathways to regulate axon outgrowth. One signaling molecule appears to be Abelson Tyrosine Kinase, a major regulator of actin dynamics. We are seeking to understand how Frazzled and Abelson cooperate to guide axons across the midline. This project utilizes biochemical and cellular techniques to understand how Frazzled and Abelson physically interact, while genetic manipulations help us understand how they work in vivo to establish axon connections.
A second project examines the role of Adhesion G-Protein coupled receptors (GPCRs) in the formation of the embryonic nerve cord. GPCRs are familiar receptors for hormones and neurotransmitters that activate trimeric G-proteins. The growing family of Adhesion GPCRs is thought to activate G-proteins in response to adhesive conditions dictated by their extracellular domains. We are using the Drosophila genetic toolbox to begin testing whether these receptors might play a role in the development of the nerve cord.
