Electrostatic Interactions Constrain Intracellular Diffusion Models in Mammalian Cells
Key Highlights
Biology · Cell Biology
A new study published in the Proceedings of the National Academy of Sciences demonstrates that electrostatic interactions fundamentally limit the applicability of porous-media models for predicting intracellular diffusion in mammalian cells. The researchers found that molecular charge and ionic strength, rather than solely the physical crowding of the cytoplasm, govern the mobility of biomolecules inside living cells. For your interest in cellular and tissular disruptions, these findings provide a more accurate framework for understanding how intracellular transport and molecular interactions are altered in pathological states, including those underlying fertility and aging-related cellular decline.
