Cell homeostasis and function rely on well-orchestrated communication between different organelles. This communication is ensured by signaling pathways and membrane contact sites between organelles. Many players involved in organelle crosstalk have been identified, predominantly proteins and ions. The role of lipids in interorganelle communication remains poorly understood. With the development and broader availability of methods to quantify lipids, as well as improved spatiotemporal resolution in detecting different lipid species, the contribution of lipids to organelle interactions starts to be evident. However, the specific roles of various lipid molecules in intracellular communication remain to be studied systematically. We summarize new insights in the interorganelle communication field from the perspective of organelles and discuss the roles played by lipids in these complex processes.
