Periodic limb movements during sleep (PLMS) is a sleep-related movement disorder characterized by repetitive limb movements during sleep, seen predominantly in the legs but also occasionally involving the arms. These movements may be associated with arousals that can lead to increases in sympathetic tone, resulting in tachycardia and elevated systolic blood pressure. Chronic sustained tachycardia...
Electrical synapses are abundant in the vertebrate brain, but their functional and molecular complexities are still poorly understood. We report here that electrical synapses between auditory afferents and goldfish Mauthner cells are constructed by apposition of hemichannels formed by two homologs of mammalian connexin 36 (Cx36) and that, while Cx35 is restricted to presynaptic hemiplaques, Cx34.7...
Mammalian dynamin is responsible for scission of endocytic vesicles from the plasma membrane. A previous study showed that Vps1, a yeast dynamin-like protein, plays an important role in pheromone receptor internalization (Yu and Cai, 2004; J. Cell Sci. 117, 3839–3853). However, the details of how Vps1 acts in various phases of endocytosis including early internalization of the endocytic vesicle are...
