Cargo trafficking between endosomes and the trans-Golgi network

Histochem Cell Biol. 2013 Sep;140(3):307-15. doi: 10.1007/s00418-013-1125-6. Epub 2013 Jul 14.

Abstract

The retrograde membrane transport pathways from endosomes to the trans-Golgi network (TGN) are now recognized as critical intracellular pathways to recycle and shuttle a selective subgroup of membrane proteins, including sorting receptors, membrane-bound enzymes, transporters, as well as providing an avenue for the intracellular transport of various bacterial toxins. Multiple pathways from endosomes to the TGN have now been defined which differ between the cargo transported and the machinery used. Here, we review advances in these pathways and the requirement for TGN organization, and also discuss the development of unbiased analytical approaches to quantitatively track cargo that use these endosome-to-TGN pathways.
