Neurotransmitter transporters are key determinants of synaptic strength and studies over the past two decades have clearly demonstrated that compromised transporter function, either via genetic manipulation or intrinsic to neuropsychiatric disorders, has a profound impact on behavior and synaptic homeostasis. Transporters are dynamically regulated by numerous intracellular signaling pathways, many of which acutely alter transporter plasma membrane expression via endocytic trafficking. Given the importance of transport function in synaptic function, copious attention has been devoted to understanding the molecular mechanisms governing transporter cell surface stability. In this chapter, we provide a comprehensive overview of the available methods used to probe constitutive and regulated transporter endocytic trafficking both in cultured cells and ex vivo brain slices. Detailed protocols are provided and both the advantages and limitations of the various methodologies are considered.
