WebFeb 20, 2004 · In observing axonal aggregates in Htt-Q128-expressing animals, it was noted that the diameter of Htt aggregates often exceeded that of normal larval axons. This suggested that large Htt aggregates might physically block axonal transport, as would be manifested by axonal swellings at the sites of blockage. f63-dclnl45035-12

WebNov 12, 2009 · Axonal transport, the process by which membrane-bound organelles and soluble protein complexes are transported into and out of axons, ensures proper function of the neuron, including that of the synapse. As such, abnormalities in axonal transport could lead to neuronal pathology and disease.

Axonal transport, also called axoplasmic transport or axoplasmic flow, is a cellular process responsible for movement of mitochondria, lipids, synaptic vesicles, proteins, and other organelles to and from a neuron's cell body, through the cytoplasm of its axon called the axoplasm.
