Traffic jams II: an update of diseases of intracellular transport.

Abstract

As more details emerge on the mechanisms that mediate and control intracellular transport, the molecular basis for variety of human diseases has been revealed. In turn, disease pathology and physiology shed light on the intricate controls that regulate intracellular transport to assure proper cellular and tissue function and homeostasis. We previously listed a number of diseases that are the result of defects in intracellular transport, or cause defects in intracellular transport. (Aridor M, Hannan LA. Traffic Jam: A compendium of human diseases that affect intracellular transport processes. Traffic 2000; 1: 836-851). This Toolbox updates the previous list to include additional disorders that were recently identified to be related to intracellular trafficking. In the time since we have published our first list there have been significant advances in understanding of the molecular basis of these defects. Such advances will pave the way to future effective therapeutics.
