Researchers from the Max Planck Institute for Dynamics and Self-Organization investigated how the exchange of molecules between the cell membrane and the cell interior influences the formation and growth of membrane-embedded molecular clusters, known as condensates. They found that both active and passive membrane exchange mechanisms play a significant role in shaping the size distribution and number of these clusters. The study provides a physics-based framework for understanding how cells regulate the organization of functional molecules on their surfaces.
Why it matters
Understanding how membrane clusters form and are regulated has implications for fields such as cell signaling, drug delivery, and the development of therapies targeting membrane-associated proteins involved in disease.
Cellular membranes not only constitute a barrier, but they also accommodate a plethora of different molecules for sensing and ensuring cellular function. These molecules often cluster together, forming condensates embedded in the membrane. A team of physicists from MPI-DS investigated how the exchange of material with the interior of the cell affects the size and number of such clusters.
