Reporting their results in the 30 June issue of Science (p 95), the researchers say that they found axons of neurons which terminate among clusters of trophocytes. (newscientist.com)
MS is a debilitating neurological disease caused by the destruction of oligodendrocytes, cells that build the myelin sheaths that surround the signal transmitting axons of neurons. (sciencemag.org)
Unexpectedly, the team discovered a thick band of microtubules, a component of the cell's cytoskeleton, that extended from the axon of the neuron into the synaptic terminal and then looped around the interior periphery of the terminal. (sciencedaily.com)
