Lipid droplets are organelles that store neutral lipids in cells.
On September 10, 2021, Peng Li’s team from Tsinghua University published an online publication in the Journal of Developmental Cell entitled "Cidec produces lipids through gel-like phase separation, which can promote lipid droplet fusion through a disc-like structure" (A gel-like condensation).
Many studies in the past ten years have shown that protein enrichment on specific subcellular organelles caused by phase separation is a necessary factor for promoting the control of specific complex biological functions
In summary, this study reveals that membrane-limited Citec two-dimensional phase separation is the basis for lipid droplet interaction, lipid droplet fusion disc structure formation and lipid droplet fusion, and points out that this type of membrane-bound two-dimensional phase separation may also be involved.
