In higher vertebrates, the segmental organization of peripheral spinal nerves is established by a repulsive mechanism whereby sensory and motor axons are excluded from the posterior half-somite. A number of candidate axon repellents have been suggested to mediate this barrier to axon growth, including Sema3A, Ephrin-B, and peanut agglutinin (PNA)-binding(More)
The study of spinal nerve trajectories in higher vertebrate embryos has revealed an inherent polarity within somites along the antero-posterior axis, and provides a simple system in which to study the factors that influence axon pathfinding. We argue that the orientation of spinal axons is determined by the simultaneous operation of two distinct guidance(More)
Phospholipase D2 (PLD2) is an enzyme that produces phosphatidic acid (PA), a lipid messenger molecule involved in a number of cellular events including, through its membrane curvature properties, endocytosis. The PLD2 knock out (PLD2KO) mouse has been previously reported to be protected from insult in a model of Alzheimer's disease. We have further analysed(More)
