An interaction between the brown fat protein CIDEA and the phospholipid phosphatidic acid is vital for the expansion of intracellular lipid droplets for energy storage.
In parallel to protein-driven processes, characteristic physicochemical properties of the endoplasmic reticulum membrane modulate intracellular fat accumulation and lipid droplet formation.
Seipin oligomers dynamically interact with small, nascent lipid droplets near the endoplasmic reticulum to convert them into larger, mature lipid droplets in a newly identified step of lipid droplet formation.

The targeting of proteins from the endoplasmic reticulum to lipid droplets relies on surface modulation of the lipid droplet by the Arf1/COPI machinery.
Histones bound to lipid droplets inside cells offer protection against bacteria in flies, and possibly mice, thus suggesting a possible new innate immunity pathway.

The amphipathic helix of perilipin 4 relies on the organization of its polar residues to form a remarkably immobile and stable protein layer on the surface of lipid droplets.

VPS13A is associated with the endoplasmic reticulum, mitochondria and lipid droplets and is required for cellular processes that require interaction between these organells.
Intracellular growth of the bacterial pathogen Legionella pneumophila in the amoeba Dictyostelium discoideum implicates a bacterial fatty acid transporter as well as dynamic interactions of the distinct membrane-bound replication compartment with host cell lipid droplets.
