FM Dyes in Vesicle Recycling

2023
FM dyes are a class of fluorescent molecules that has found important use in studying the vesicle recycling process. By virtue of a chemical structure, these molecules can insert themselves into the outer leaflet of phospholipid bilayer membranes. After membrane insertion, they are internalized into the cell via endocytosed vesicles, and released when these vesicles recycle back to the membrane. Since, these dyes fluoresce strongly in the hydrophobic environment within membranes and weakly in...

This work outlines a protocol to achieve dynamic, non-invasive monitoring of heat transfer from laser-irradiated gold nanoparticles to tBLMs. The system combines impedance spectroscopy for the real-time measurement of conductance changes across the tBLMs, with a horizontally focused laser beam that drives gold nanoparticle illumination, for heat production.

Structure of Lipids

Lipids include a diverse group of compounds that are largely nonpolar in nature. This is because they are hydrocarbons that include mostly nonpolar carbon-carbon or carbon-hydrogen bonds. Non-polar molecules are hydrophobic (“water fearing”), or insoluble in water. Lipids perform many different functions in a cell. Cells store energy for long-term use in the form of fats. Lipids also provide insulation from the environment for plants and animals. For example, they help keep aquatic birds and...

Here, we present a protocol to use pre-synthesized polymeric products derived from fungal laccase-catalyzed polymerization of plant phenols, either with or without mordant agents (e.g., FeSO4), to induce detergent-resistant keratin hair dyeing within 2.5 hours.
FAQs
The interpretation of a redistributed lipid dye depends on how membranes interact. A signal appearing in a second membrane may be consistent with membrane fusion, close membrane contact, or lipid exchange, and these mechanisms represent different forms of connectivity. Distinguishing among them is important because the result can describe either direct membrane joining or transfer associated with contact.
Tracking labeled lipids can show changes in membrane composition as dye moves between cellular membranes. In neurons and glia, this provides a way to examine whether membrane interactions accompany remodeling or trafficking. The resulting redistribution is therefore informative not only about where a dye goes, but also about how membrane organization changes during cellular communication.
Redistribution between neuronal and glial membranes can provide evidence about cellular communication and membrane connectivity. When examined alongside synaptic vesicle dynamics or membrane remodeling, the transfer pattern helps relate lipid movement to processes occurring at interacting cells. This makes the technique useful for connecting membrane behavior with functional relationships between neural cell types.
A typical workflow introduces a lipid-soluble fluorescent dye into one cellular membrane and then monitors whether the label redistributes to another membrane in a living system. The experiment centers on following the dye after labeling, while relating its movement to possible fusion, close membrane contact, or lipid exchange. This sequence links the observed signal to membrane interactions.
In neuroscience, the approach can be applied to communication between neurons and glial cells, synaptic vesicle dynamics, membrane remodeling, and cellular connectivity. These uses allow investigators to examine membrane behavior in contexts where cells interact or reorganize their membranes. It therefore supports studies that connect lipid movement with both cellular structure and neural signaling processes.
Measurements of lipid redistribution can reveal how membrane composition and trafficking change across development, signaling, injury, or disease. Comparing transfer in these contexts helps identify whether membrane interactions or trafficking behavior vary with cellular state. In this way, the technique provides a membrane-level readout for investigating changing neural and glial conditions.
