Abstract

The surface potential of biological membranes varies according to their lipid composition. We devised genetically encoded probes to assess surface potential in intact cells. These probes revealed marked, localized alterations in the charge of the inner surface of the plasma membrane of macrophages during the course of phagocytosis. Hydrolysis of phosphoinositides and displacement of phosphatidylserine accounted for the change in surface potential at the phagosomal cup. Signaling molecules such as K-Ras, Rac1, and c-Src that are targeted to the membrane by electrostatic interactions were rapidly released from membrane subdomains where the surface charge was altered by lipid remodeling during phagocytosis.

  • Phosphatidylinositide lipids synthesized by stage-specific phosphatidyl inositol kinases at the cytoplasmic sheet of phagosomal membranes are specific for different phagosome stages and functionally contribute to maturation-associated vesicle fusion and actin-polymerization associated processes.

    “In addition to stage-specific v-, t-SNAREs and Rab proteins, phosphatidylinositide (PI) lipids synthesized by stage-specific phosphatidyl inositol kinases (PIK) at the cytoplasmic sheet of phagosomal membranes are specific for different phagosome stages and functionally contribute to maturation-associated vesicle fusion and actin-polymerization associated processes (16).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
