Zitosoleko lipido-tanten sorrera eta erabilera

Abstract

Although lipid droplets (LD) have traditionally been considered inert lipid deposits nowadays they are considered true organelles given their complexity and involvement in metabolism and other cellular processes. LDs originate in endoplasmic reticulum and after release they show growth, transference of lipids and proteins, fusion or specific interactions with other organelles. Lipids stored in LDs can be used as fuel or metabolic precursors, and for such purposes they are released in tightly controlled lipolysis or lipophagy processes. This work summarises all these aspects as well as other non-canonical LD functions.
