Title:	Immune cell membrane protrusions: a sensory organelle
Creators Name:	Zünd, Tamara, Vogel, Viola and Klotzsch, Enrico
Abstract:	Immune cells possess a remarkable set of complementary surface protru-sions, such as microvilli, podosomes, filopodia, and lamellipodia, which play pivotal roles in the sensing of and responding to varied environmental cues. These dynamic structures maximize the surface area–to–volume ratio of immune cells, which in turn enhances cell–cell and cell–matrix interac-tions, while generating pulling and pushing forces, allowing immune cells to integrate biochemical and physical cues from their surroundings. This review discusses recent insights into the structures and dynamics of dif-ferent protrusions, the molecular machinery behind mechanosensing, the differential role of protrusions for different subsets of immune cells, and the cutting-edge technology that has advanced our understanding of those protrusions.
