ANTEROGRADE TRANSPORT Meaning and
Definition
-
Anterograde transport is a fundamental process in cell biology that refers to the movement of cellular molecules and organelles from the cell body towards the axon terminals or towards the periphery of the cell. It is one of the two major types of intracellular transport, the other being retrograde transport.
In anterograde transport, molecules and organelles are carried along the microtubules of the cell's cytoskeleton in a highly organized manner. This transport is facilitated by molecular motor proteins, such as kinesin, which utilize ATP energy to move along the microtubules in a unidirectional manner. These motor proteins bind to specific cargoes and transport them towards the distal regions of the cell.
Anterograde transport is crucial for the correct function and maintenance of a cell. It allows for the delivery of critical molecules, such as proteins, lipids, and vesicles, to their intended destinations. For example, in neurons, anterograde transport is responsible for delivering neurotransmitters and other essential components to the synapses, thereby enabling communication between neurons.
Disruptions or impairments in anterograde transport can have severe consequences for cellular function and overall organism health. It has been associated with various neurodegenerative diseases, including Alzheimer's disease and Parkinson's disease, where the abnormal accumulation of misfolded proteins can disrupt the transport of essential molecules, leading to neuronal dysfunction and cell death.
In summary, anterograde transport is a vital cellular process that ensures the proper transport of molecules and organelles towards the growth cone or axon terminals, facilitating cellular function and maintaining overall cell health.

Etymology of ANTEROGRADE TRANSPORT
The word "anterograde transport" has its origins in two Latin roots: "ante", meaning "before" or "in front", and "gradus", meaning "step" or "walk". In biology and neurology, it refers to the movement of molecules or organelles within a cell, from the cell body towards the axon terminals. The term "anterograde" is used to describe this directional movement, as it is the opposite of "retrograde transport", which refers to the movement in the opposite direction, from the axon terminals towards the cell body.
