retrograde transport
Reverse cellular shipping
Retrograde transport is the movement of materials backward along a pathway, opposite to the normal or primary direction of flow.
In cell biology, it refers to the transport of proteins and other molecules from the cell's outer regions back toward the nucleus, or from the Golgi apparatus back to the endoplasmic reticulum.
In neuroscience, retrograde transport moves substances from nerve terminals back to the cell body.
Certain toxins and viruses exploit retrograde transport to reach the nervous system.
