Brain function revealed by single-molecule imaging
QD-SPT: A powerful tool to visualize the molecular dynamics
According to the fluid mosaic model, plasma membrane molecules such as lipids and transmembrane proteins have the ability to undergo lateral diffusion freely throughout the cell. In some cell types, however, specific membrane molecules are concentrated in cellular microdomains, by overcoming the randomizing effects of free diffusion. This polarized distribution of membrane molecules is crucial for various cell functions, thus it is important to understand the mechanism through which the cell regulates the lateral diffusion of membrane molecules.
Quantum-dot single particle tracking (QD-SPT), a single molecule imaging technique using semiconductor nanocrystal quantum dots as a fluorescent probe, is a powerful tool to analyze the behavior of proteins and lipids on the plasma membrane. QD-SPT experiments that allowed us to obtain further insights into the strategy and physiological relevance of membrane self-organization in neurons and astrocytes, two major component cells in the brain.
What does membrane dynamics tell us?
Single-molecule resolution imaging has highlighted the existence and importance of self-organization mechanisms in neurons and glia. Additionally, a growing body of evidence demonstrates that neuronal and glial receptor dynamics become abnormal in disease states. Altered molecular diffusion dynamics comprise an important pathological phenotype.
