The movement of a phospholipid molecule from one leaflet of a membrane bilayer to the opposite leaflet.

The movement of a phospholipid molecule from one leaflet of a membrane bilayer to the opposite leaflet.

A process in which an ion is transported from one side of a membrane to the other by means of some agent such as a transporter or pore.

The regulated exocytosis of secretory granules containing preformed mediators such as proteases, lipases, and inflammatory mediators by a neutrophil.

The process in which a precursor cell type acquires the specialized features of a pre-B cell. Pre-B cells follow the pro-B cell stage of immature B cell differentiation and undergo rearrangement of heavy chain V, D, and J gene segments.

The directed movement of charged atoms or small charged molecules into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.

The directed movement of aminophospholipids into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. Aminophospholipids contain phosphoric acid as a mono- or diester and an amino (NH2) group.

The movement of a phospholipid molecule from one leaflet of a membrane bilayer to the opposite leaflet.

Any process that activates or increases the frequency, rate or extent of B cell differentiation.

The irregular network of unit membranes, visible only by electron microscopy, that occurs in the cytoplasm of many eukaryotic cells. The membranes form a complex meshwork of tubular channels, which are often expanded into slitlike cavities called cisternae. The ER takes two forms, rough (or granular), with ribosomes adhering to the outer surface, and smooth (with no ribosomes attached).

A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.

The component of a membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane.

An organelle consisting of a network of tubules that functions in targeting molecules, such as receptors transporters and lipids, to the plasma membrane.

The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.

Organized structure of distinctive morphology and function, bounded by a single or double lipid bilayer membrane and occurring within the cell. Includes the nucleus, mitochondria, plastids, vacuoles, and vesicles. Excludes the plasma membrane.

The lipid bilayer surrounding the lysosome and separating its contents from the cell cytoplasm.

The lipid bilayer surrounding the lysosome and separating its contents from the cell cytoplasm.

A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.

An organelle consisting of a network of tubules that functions in targeting molecules, such as receptors transporters and lipids, to the plasma membrane.

The inner, i.e. lumen-facing, lipid bilayer of the nuclear envelope.

The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.

The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.

The lipid bilayer surrounding an azurophil granule, a primary lysosomal granule found in neutrophil granulocytes that contains a wide range of hydrolytic enzymes and is released into the extracellular fluid.

The lipid bilayer surrounding a specific granule, a granule with a membranous, tubular internal structure, found primarily in mature neutrophil cells. Most are released into the extracellular fluid. Specific granules contain lactoferrin, lysozyme, vitamin B12 binding protein and elastase.

Organized structure of distinctive morphology and function, bounded by a single or double lipid bilayer membrane and occurring within the cell. Includes the nucleus, mitochondria, plastids, vacuoles, and vesicles. Excludes the plasma membrane.

The lipid bilayer surrounding a tertiary granule.
