Abstract:
Efficient phagocytosis of apoptotic cells (efferocytosis) is essential for immune homeostasis. Phospholipids exposed on the surface of apoptotic cells, such as phosphatidylserine, supply important "eat-me" signals. Liposomes are lipid bilayer vesicles that can be generated from one or several types of phospholipids of interest. Thus, these vesicles offer versatility, flexibility, and, importantly, a three-dimensional structure for studying the interaction between lipids and their receptors as well as the lipid-receptor interaction-mediated signaling events controlling efferocytosis by cells like professional phagocytes. Here, we describe methods to prepare liposomes, perform liposome-based lipid-receptor binding assays, use liposomes to block efferocytosis, and utilize liposome-coated beads as apoptotic cell surrogates for phagocytosis. © 2018 by John Wiley & Sons, Inc.
