Axon regeneration in C. elegans.
Single axon transection by laser surgery has made Caenorhabditis elegans a new model for axon regeneration. Multiple conserved molecular signaling modules have been discovered through powerful genetic screening. In vivo imaging with single cell and axon resolution has revealed unprecedented cellular dynamics in regenerating axons. Information from C. elegans has greatly expanded our knowledge o...
متن کاملAxon regeneration genes identified by RNAi screening in C. elegans.
Axons of the mammalian CNS lose the ability to regenerate soon after development due to both an inhibitory CNS environment and the loss of cell-intrinsic factors necessary for regeneration. The complex molecular events required for robust regeneration of mature neurons are not fully understood, particularly in vivo. To identify genes affecting axon regeneration in Caenorhabditis elegans, we per...
متن کاملMAP kinase cascades regulating axon regeneration in C. elegans
Mitogen-activated protein kinase (MAPK) signaling cascades are activated by diverse stimuli such as growth factors, cytokines, neurotransmitters and various types of cellular stress. Our evolving understanding of these signal cascades has been facilitated by genetic analyses and physiological characterization in model organisms such as the nematode Caenorhabditis elegans. Genetic and biochemica...
متن کاملDistinct cellular and molecular mechanisms mediate initial axon development and adult-stage axon regeneration in C. elegans.
The molecular and cellular mechanisms that allow adult-stage neurons to regenerate following damage are poorly understood. Recently, axons of motoneurons and mechanosensory neurons in adult C. elegans were found to regrow after being snipped by femtosecond laser ablation. Here, we explore the molecular determinants of adult-stage axon regeneration using the AVM mechanosensory neurons. The first...
متن کاملInflammation and axon regeneration.
PURPOSE OF REVIEW The inflammatory response that accompanies neural injury involves multiple cell types and effector molecules with both positive and negative effects. Inflammation is essential for normal regeneration in the peripheral nervous system, and here we review evidence that augmenting inflammation can enhance regeneration in areas of the central nervous system in which it normally doe...
