#A microtubule'roadway'in the retina helps provide energy for vision Fluorescently labeled microtubules extend from the tips of the dendrites (top) into the axon and down into the giant synaptic terminal (bottom) of a single isolated goldfish retinal
Researchers have discovered a thick band of microtubules in certain neurons in the retina that they believe acts as a transport road for mitochondria that help provide energy required for visual processing.
They require a constant supply of energy to mediate the sustained release of the contents of an enormous number of synaptic vesicles,
An intriguing new study of their subcellular structure could help explain how bipolar synaptic terminals meet such excessive energy demands.
The microtubule band appeared to associate with mitochondria--organelles known for providing energy to cells--in the synaptic terminal.
The findings suggest that these previously unknown microtubule structures provide a"roadway"for the transport of mitochondria crucial to maintain energy supplies into the synaptic terminals of these highly active neurons associated with vision.
