Book Description
Neuromuscular Junctions in Drosophila gathers the main contributions that research using the fruit fly Drosophila melanogaster has made in the area of synapse development, synapse physiology, and excitability of muscles and nerve cells. The chapters in this book represent a synthesis of major advances in our understanding of neuronal development and synaptic physiology, which have been obtained using the above approach.This book is directed to the general neuroscience audience: researchers, instructors, graduate students, and advanced undergraduates who are interested in the mechanisms of synapse development and physiology. However, the book will also be a valuable resource for those that use the fruit fly as a model system in their laboratories. Key Features* Synthesizes the genetic approaches used to study synaptic development and function at the neuromuscular junction, using flies as a model system* Covers major recent advances in muscle development, pathfinding, synapse maturation and plasticity, exo- and endocytosis, and ion channel function* Written in clear language that is easily understandable to readers not already familiar with fruit fly research* Includes numerous diagrams and extensive reference lists

Book Description
The Drosophila larval neuromuscular junction (NMJ) has become one of the most powerful model systems to ask key neurobiological questions. This synapse is unparalleled by its accessibility, its simplicity, and the ability to manipulate genes important for synapse development and function. Its synapses have properties shared by many organisms including humans. The vast majority of genes that when mutated cause congenital disorders of the nervous system in humans, are present in the fruit fly genome, and fly models of human disorders are available. Thus, this preparation is a powerful tool to understand the normal function of these genes. This book reviews outstanding work by recognized leaders in the fields of Drosophila cellular neurogenetics including developmental neurobiology, mechanisms of synaptic function, and experience dependent changes at synapses. The book also includes step-by-step protocols to study the cellular biology of the NMJ, making it a vital resource for researchers beginning their investigations with this system, for those who are training students and postdoctoral fellows in this area, or simply as a general reference material for neuroscientists and neuroscience professors in general. * Provides a synthesis of the main topics in modern neurogenetics* Includes step-by-step protocols for the use of the Drosophila NMJ system in neurobiology lab research* Offers genetic approaches to study synapse development and function*

Book Description
The Drosophila neuromuscular junction (NMJ) is capable of rapidly budding new presynaptic varicosities over the course of minutes in response to elevated neuronal activity. Using live imaging of synaptic growth, we characterized this dynamic process and demonstrate that rapid bouton budding requires retrograde BMP signaling and local alteration in the presynaptic actin cytoskeleton. BMP acts during development to provide competence for rapid synaptic growth by regulating the levels of the Rho GEF trio, a transcriptional output of BMP-Smad signaling. In a parallel pathway, we find that the BMP type 11 receptor Wit signals through the effector protein LIM domain kinasel (Limk) to regulate bouton budding. Limk interfaces with structural plasticity by controlling the activity of the actin depolymerizing protein Cofilin. Expression of constitutively active or inactive Cofilin in motor neurons demonstrates that increased Cofilin activity promotes rapid bouton formation in response to elevated synaptic activity. Correspondingly, overexpression of Limk, which inhibits Cofilin, inhibits bouton budding. Live imaging of the presynaptic F-actin cytoskeleton reveals that activity-dependent bouton addition is accompanied by formation of new F-actin puncta at sites of synaptic growth. Pharmacological disruption of actin turnover inhibits bouton budding, indicating local changes in the actin cytoskeleton at preexisting boutons precede new budding events. We propose that developmental BMP signaling potentiates NMJs for rapid activity-dependent structural plasticity that is achieved by muscle release of retrograde signals that regulate local presynaptic actin cytoskeletal dynamics.
