Any process that activates or increases the frequency, rate or extent of addition of phosphate groups to amino acids within a protein.

The regulated exocytosis of secretory granules containing preformed mediators such as histamine and serotonin by a platelet.

Any process that activates or increases the frequency, rate, or extent of leukocyte migration.

Any process that activates or increases the frequency, rate, or extent of cellular extravasation.

A vesicle-mediated transport process that results in the engulfment of external particulate material by phagocytes and their delivery to the lysosome. The particles are initially contained within phagocytic vacuoles (phagosomes), which then fuse with primary lysosomes to effect digestion of the particles.

The attachment of a plasma membrane adhesion molecule in one cell to an identical molecule in an adjacent cell.

The attachment of a leukocyte to another cell via adhesion molecules.

The cellular process in which a signal is conveyed to trigger a change in the activity or state of a cell. Signal transduction begins with reception of a signal (e.g. a ligand binding to a receptor or receptor activation by a stimulus such as light), or for signal transduction in the absence of ligand, signal-withdrawal or the activity of a constitutively active receptor. Signal transduction ends with regulation of a downstream cellular process, e.g. regulation of transcription or regulation of a metabolic process. Signal transduction covers signaling from receptors located on the surface of the cell and signaling via molecules located within the cell. For signaling between cells, signal transduction is restricted to events at and within the receiving cell.

The process in which a cell in an organism interprets its surroundings.

A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of an extracellular matrix.

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

Any process that stops, prevents, or reduces the frequency, rate or extent of actin polymerization.

Any process that stops or reduces the rate of GTP hydrolysis by a GTPase.

The migration of a monocyte from the blood vessels into the surrounding tissue.

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

Any process that activates or increases the frequency, rate or extent of the phosphorylation of peptidyl-tyrosine.

Any process that stops, prevents, or reduces the frequency, rate or extent of the phosphorylation of peptidyl-tyrosine.

The movement of a leukocyte within or between different tissues and organs of the body.

The passage of a leukocyte between the tight junctions of endothelial cells lining blood vessels, typically the fourth and final step of cellular extravasation.

The aggregation, arrangement and bonding together of a set of components to form a tight junction, an occluding cell-cell junction that is composed of a branching network of sealing strands that completely encircles the apical end of each cell in an epithelial sheet.

Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of an interferon-gamma stimulus. Interferon gamma is the only member of the type II interferon found so far.

Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of an organic cyclic compound stimulus.

Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a transforming growth factor beta stimulus.

The process whose specific outcome is the progression of the glomerular endothelium over time, from its formation to the mature structure. The glomerular endothelium is an epithelial tissue that covers the internal surfaces of the glomerulus.

The migration of a neutrophil from the blood vessels into the surrounding tissue.

The attachment of one cell to another cell via adhesion molecules.

The attachment of one cell to another cell via adhesion molecules that are at least partially embedded in the plasma membrane.

Projection at the leading edge of a crawling cell; the protrusions are supported by a microfilament meshwork.

That part of a multicellular organism outside the cells proper, usually taken to be outside the plasma membranes, and occupied by fluid.

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.

A cell junction that forms a connection between two or more cells in a multicellular organism; excludes direct cytoplasmic junctions such as ring canals.

The external part of the cell wall and/or plasma membrane.

The lipid bilayer surrounding a secretory granule.

The lipid bilayer surrounding the platelet alpha granule.

A stable assembly of two or more macromolecules, i.e. proteins, nucleic acids, carbohydrates or lipids, in which at least one component is a protein and the constituent parts function together.

A vesicle that is released into the extracellular region by fusion of the limiting endosomal membrane of a multivesicular body with the plasma membrane. Extracellular exosomes, also simply called exosomes, have a diameter of about 40-100 nm.
