This article presents a method for preparing compound Giant Unilamellar Vesicles (cGUVs) with a vesicle-in-vesicle structure, with customized electrical conductivity in inner, annular, and outer regions. Electroformation synthesizes simple GUVs, which are transformed into stomatocytes and cGUVs via osmotic shock, providing a valuable model for studying the biophysics of nucleated cells.

We present a protocol to rapidly form giant polymer vesicles (pGVs). Briefly, polymer solutions are dehydrated on dried agarose films adhered to coverslips. Rehydration of the polymer films results in rapid formation of pGVs. This method greatly advances the preparation of synthetic giant vesicles for direct applications in biomimetic studies.

Reconstituting functional membrane proteins into giant liposomes of defined composition is a powerful approach when combined with patch-clamp electrophysiology. However, conventional giant liposome production may be incompatible with protein stability. We describe protocols for producing giant liposomes from pure lipids or small liposomes containing ion channels.

Many proteins in the cell sense and induce membrane curvature. We describe a method to pull membrane nanotubes from lipid vesicles to study the interaction of proteins or any curvature-active molecule with curved membranes in vitro.
FAQs
Persistent stimulation keeps macrophages activated and promotes their adhesion to one another. Coordinated changes at the cell surface then allow neighboring membranes to merge, producing one unusually large cell with multiple nuclei. This response links the duration of the stimulus to the appearance of multinucleated cells and reflects an attempt by innate immune cells to manage material that remains difficult to clear.
These labels identify recognized forms associated with granulomatous inflammation. The important interpretive distinction is the surrounding biological problem: giant cells may occur in response to indigestible material, damaged tissue, or pathogens that resist clearance. Examining nuclear organization and cell appearance alongside tissue context can therefore help researchers interpret the persistent immune stimulus rather than treating cell size alone as diagnostic.
Sustained stimulation maintains the macrophage response and favors continued cell-to-cell interaction. As membranes fuse, the resulting multinucleated cells can help contain indigestible materials, damaged tissue, or pathogens that resist clearance. Their formation therefore reflects an ongoing containment strategy within persistent inflammation, rather than a completed resolution of the initiating problem.
Investigators should look for unusually large cells containing multiple nuclei, then assess nuclear organization and tissue context. Finding these cells within granulomatous inflammation can support interpretation of a chronic immune response, while association with indigestible material, damaged tissue, or difficult-to-clear pathogens helps frame the likely biological problem. Morphology is informative but should be interpreted with its inflammatory setting.
It is particularly relevant when investigators or clinicians study chronic infections, granulomatous diseases, or foreign-body reactions. Recognizing the cells can provide evidence that innate immune responses are addressing a persistent problem, while their nuclear organization may offer additional clues about the response. The finding supports diagnosis and investigation, but its meaning depends on the associated tissue and stimulus.
In infection research, the phenomenon connects macrophage behavior with the challenge of persistence. Activated cells do not simply encounter a stimulus; they can reorganize through adhesion and fusion into a structure suited to containing pathogens that resist clearance. Studying this outcome helps researchers examine how innate immune cells respond to continuing infection and regulate inflammation when elimination is difficult.
