RESUMEN
The plasma membrane serves as the primary barrier between the cell's interior and its external surroundings, which places it at the forefront of intercellular communication, receptor signal transduction and the integration of mechanical forces from outside. Most of these signals are largely dependent on the plasma membrane heterogeneity which relies on lipid-lipid and lipid-protein interactions and the lateral nano-distribution of lipids organized by the dynamic network of cortical actin. In this review, we undertake an in-depth exploration of recent discoveries, which contribute significantly to the evolution from raft model to lipid nanodomains. Specifically, we will focus on their role in membrane receptor-mediated signaling in the context of cell membrane mechanics.
