Human Neutrophil With S. Typhimurium (IMAGE) PLOS Caption This image depicts a single cell experiment in which a human neutrophil was picked up by a micropipette (top panel) and brought into close contact with S. Typhimurium cells immobilized by optical tweezers. The neutrophil extends a pseudopod towards the bacteria (left bottom panel) and is allowed to phagocytose the pathogen (bottom right panel).
