The binding of a cell to the extracellular matrix that contributes to the directed movement of an ameboid cell.

The binding of a cell to the extracellular matrix that contributes to the directed movement of an ameboid cell.

The attachment of a cell, either to another cell or to an underlying substrate such as the extracellular matrix, via cell adhesion molecules.

The binding of a cell to the extracellular matrix via adhesion molecules.

The binding of a cell to the extracellular matrix via adhesion molecules.

A series of molecular signals initiated by the binding of extracellular ligand to an integrin on the surface of a target cell, and ending with regulation of a downstream cellular process, e.g. transcription.

A series of molecular signals initiated by the binding of extracellular ligand to an integrin on the surface of a target cell, and ending with regulation of a downstream cellular process, e.g. transcription.

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.

The attachment of a cell to a cell of a different type via adhesion molecules.

The attachment of a cell to a cell of a different type via adhesion molecules.

The morphogenetic process that results in flattening of a cell as a consequence of its adhesion to a substrate.

The morphogenetic process that results in flattening of a cell as a consequence of its adhesion to a substrate.

The receptor metabolic process that results in grouping of a set of receptors at a cellular location, often to amplify the sensitivity of a signaling response.

The receptor metabolic process that results in grouping of a set of receptors at a cellular location, often to amplify the sensitivity of a signaling response.

Any process that modulates the frequency, rate or extent of the immune response, the immunological reaction of an organism to an immunogenic stimulus.

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

Transient adhesive interactions between leukocytes and endothelial cells lining blood vessels. Carbohydrates on circulating leukocytes bind selectins on the vessel wall causing the leukocytes to slow down and roll along the inner surface of the vessel wall. During this rolling motion, transitory bonds are formed and broken between selectins and their ligands. Typically the first step in cellular extravasation (the movement of leukocytes out of the circulatory system, towards the site of tissue damage or infection).

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

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

A protein complex that is composed of one alpha subunit and one beta subunit, both of which are members of the integrin superfamily of cell adhesion receptors; the complex spans the plasma membrane and binds to extracellular matrix ligands, cell-surface ligands, and soluble ligands.

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

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

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

An integrin complex that comprises one alpha4 subunit and one beta7 subunit.

An integrin complex that comprises one alpha4 subunit and one beta7 subunit.

Any protein complex that undergoes combination with a hormone, neurotransmitter, drug or intracellular messenger to initiate a change in cell function.

Any protein complex that undergoes combination with a hormone, neurotransmitter, drug or intracellular messenger to initiate a change in cell function.

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.
