The importance of understanding cellular membrane functions through experimental systems mimicking their biochemical composition and biophysical properties is emphasized. The interplay between membrane components and physical properties of the plasma membrane is discussed, highlighting the significance for biomimetic studies. The advantages and considerations of different model membrane systems are reviewed, with an emphasis on their contributions to understanding immune cell signaling, particularly the immunological synapse.
Understanding the broad variety of functions encoded in cellular membranes requires experimental systems mimicking both their biochemical composition and biophysical properties. Here, we review the interplay between membrane components and the physical properties of the plasma membrane worth considering for biomimetic studies. Later, we discuss the main advantages and caveats of different model membrane systems. We further expand on how the use of model systems has contributed to the understanding of immune cell signaling, with a specific focus on the immunological synapse. We discuss the similarities of immune synapses observed for innate and adaptive immune cells and focus on the physical principles underlying these similarities.
