Single-Particle Tracking of AMPA Receptor-Containing Vesicles.

ABSTRACT: AMPA-type receptors are transported large distances to support synaptic plasticity at distal dendritic locations. Studying the motion of AMPA receptor⁺ vesicles can improve our understanding of the mechanisms that underlie learning and memory. Nevertheless, technical challenges that prevent the visualization of AMPA receptor⁺ vesicles limit our ability to study how these vesicles are trafficked. Existing methods rely on the overexpression of fluorescent protein-tagged AMPA receptors from plasmids, resulting in a saturated signal that obscures vesicles. Photobleaching must be applied to detect individual AMPA receptor⁺ vesicles, which may eliminate important vesicle populations from analysis. Here, we present a protocol to study AMPA receptor⁺ ves
