Key result
Adipocyte caveolae may modulate fatty acid flux across the plasma membrane.
Why the study?
The functions of adipocyte caveolae remain controversial and require further experimental scrutiny to clarify their roles in fatty acid flux modulation and other cellular processes.
This review highlights the potential role of adipocyte caveolae in modulating fatty acid flux, signal transduction, and membrane trafficking.

Caveolae roles in adipocytes warrant no clinical action; leaves open their modulation of fatty acid flux for direct experiments.
It has been known for decades that the adipocyte cell surface is particularly rich in small invaginations we now know to be caveolae. These structures are common to many cell types but are not ubiquitous. They have generated considerable curiosity, as manifested by the numerous publications on the topic that describe various, sometimes contradictory, caveolae functions. Here, we review the field from an "adipocentric" point of view and suggest that caveolae may have a function of particular use for the fat cell, namely the modulation of fatty acid flux across the plasma membrane. Other functions for adipocyte caveolae that have been postulated include participation in signal transduction and membrane trafficking pathways, and it will require further experimental scrutiny to resolve controversies surrounding these possible activities.

Pilch et al. (2007) conducted a review in Adipocyte caveolae function. Adipocyte caveolae may modulate fatty acid flux across the plasma membrane, though their roles in signal transduction and membrane trafficking require further experimental scrutiny.
