Tiagabine, a drug used as an anticonvulsant, acts by inhibiting the GABA transporter 1. Neurotransmitter transporters inhibitors Vesicular transporters could provide an alternative therapeutic target for the modulation of chemical neurotransmission, as the activity of these transporters could affect the quantity of neurotransmitter released.
Betaine transporter (BGT1; SLC6A12) Creatinine transporter 1 (CT1; SLC6A8) Taurine transporter (TauT; SLC6A6) GAT1 and GAT3 are the major GABA transporters in the brain and spinal cord, expressed by both neurons and some astrocytes. [4] GAT2 and BGT1 are also expressed in the brain, but at low levels and mostly in the meninges.
This bidirectional communication between astrocytes and neurons add complexity to brain signaling, with implications for brain function and neurological disorders. [ 10 ] [ 11 ] Enzyme degradation – proteins called enzymes break the neurotransmitters down.
[10] [11] [12] An analogy is the difference in transport rates between local and express subway trains. Though both types of train travel at similar velocities between stations, the local train takes much longer to reach the end of the line because it stops at every station whereas the express makes only a few stops on the way.
Cotransmission allows for more complex effects at postsynaptic receptors, and thus allows for more complex communication to occur between neurons. In modern neuroscience, neurons are often classified by their cotransmitter. For example, striatal "GABAergic neurons" utilize opioid peptides or substance P as their primary cotransmitter.
Facilitated diffusion may occur through three mechanisms: uniport, symport, or antiport. The difference between each mechanism depends on the direction of transport, in which uniport is the only transport not coupled to the transport of another solute. [4] Uniporter carrier proteins work by binding to one molecule or substrate at a time ...

The fast axonal transport has a rate of 50–500 mm per day, while the slow axonal transport was found to be 0.4 mm per day in goldfish, 1–10 mm per day in mammalian nerve. Transport of insoluble protein contributes to the fast movement while the slow transport is transporting up to 40% - 50% soluble protein. [ 12 ]
