The intrinsic ability of injured neurons to degenerate and regenerate their axons facilitates nervous system repair; however, this ability is not engaged in all neurons and injury locations. Here, we investigate the regulation of a conserved axonal injury response pathway with respect to the location of damage in branched motoneuron (MN) axons in Drosophila larvae. The dileucine zipper kinase (DLK; also known as MAP3K12 in mammals and Wallenda (Wnd) in Drosophila) is a key regulator of diverse responses to axonal injury. In three different populations of MNs, we observed the same striking result that Wnd/DLK signaling becomes activated only in response to injuries that remove all synaptic terminals. Injuries that spared even a small part of a synaptic terminal were insufficient to activate Wnd/DLK signaling, despite the presence of extensive axonal degeneration. The regulation of injury-induced Wnd/DLK signaling occurs independently of its previously known regulator, the Hiw/PHR ubiquitin ligase. We propose that Wnd/DLK signaling regulation is linked to the trafficking of a synapse-to-nucleus axonal cargo and that this mechanism enables neurons to respond to impairments in synaptic connectivity.

NIH is the nations medical research agency - making important medical discoveries that improve health and save lives. The National Institutes of Health (NIH), a part of the U.S. Department of Health and Human Services, is the primary Federal agency for conducting and supporting medical research. Helping to lead the way toward important medical discoveries that improve peoples health and save lives, NIH scientists investigate ways to prevent disease as well as the causes, treatments, and even cures for common and rare diseases. NIH research impacts: * child and teen health, * men's health, * minority health, * seniors' health, * women's health, and * wellness and lifestyle issues. Composed of 27 Institutes and Centers, the NIH provides leadership and financial support to researchers in every state and throughout the world.
View all literature mentionsThe Canadian Institutes of Health Research (CIHR) is the Government of Canada''s agency responsible for funding health research in Canada. CIHR was created in 2000 under the authority of the CIHR Act and reports to Parliament through the Minister of Health. CIHR''s budget for 2008-09 is $928.6 million, of which $132 million is allocated to administering the Networks of Centres of Excellence and Canada Research Chair programs. CIHR was created to transform health research in Canada by: * funding more research on targeted priority areas; * building research capacity in under-developed areas such as population health and health services research; * training the next generation of health researchers; and * focusing on knowledge translation, so that the results of research are transformed into policies, practices, procedures, products and services. CIHR consists of 13 virtual institutes, a structure that is unique in the world. These innovative institutes bring together all partners in the research process - the people who fund research, those who carry it out and those who use its results - to share ideas and focus on what Canadians need: good health and the means to prevent disease and fight it when it happens. Each institute supports a broad spectrum of research in its topic areas and, in consultation with its stakeholders, sets priorities for research in those areas.
