The molecular mechanisms that generate dendrites in the CNS are poorly understood. The diffusible signal molecule Slit and the neuronally expressed receptor Robo mediate growth cone collapse in vivo. However, in cultured neurons, these molecules promote dendritic development. Here we examine the aCC motoneuron, one of the first CNS neurons to generate(More)
Chromatin of Trypanosoma cruzi epimastigotes was found to be arranged in a subunit structure by the demonstration of (i) nu-bodies, (ii) monomeric and oligomeric DNA fragments, and (iii) four basic nuclear proteins which presumably correspond to the intrinsic protein component of nucleosomes. A discrete core fragment of 140 base pairs and a basic nuclear(More)
