Making Menorahs

摘要

Highly branched neuronal processes are typical of numerous neurons. The mechanisms controlling the formation, maintenance and regeneration of neuronal trees are poorly understood. Oren-Suissa et al. (p. 1285, published online 6 May) observed the development of extensively arborized neu-rite trees-menorahs-in two highly branched mechanosen-sory neurons in Caenorhabditis elegans. EFF-1, a fusion protein known to be important for cell fusion, played a key role in arborization.
