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

The expansion of a T cell population by cell division as part of an immune response.

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

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.

Any process that mediates the transfer of information from one cell to another. This process includes signal transduction in the receiving cell and, where applicable, release of a ligand and any processes that actively facilitate its transport and presentation to the receiving cell. Examples include signaling via soluble ligands, via cell adhesion molecules and via gap junctions.

A series of molecular signals initiated by the binding of a tumor necrosis factor to a receptor on the surface of a cell, and ending with regulation of a downstream cellular process, e.g. transcription.

A series of molecular signals initiated by the binding of a tumor necrosis factor to a receptor on the surface of a cell, and ending with regulation of a downstream cellular process, e.g. transcription.

Any process that modulates the frequency, rate or extent of T cell proliferation.

Any process that activates or increases the frequency, rate or extent of the introduction of a phosphate group to a tyrosine residue of a STAT (Signal Transducer and Activator of Transcription) protein.

Any process that stops, prevents, or reduces the frequency, rate or extent of cell death by apoptotic process.

Any process that activates or increases the frequency, rate or extent of activity of the transcription factor NF-kappaB.

Any process that results in a change in state or activity of an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus by molecules of bacterial origin such as peptides derived from bacterial flagellin.

The expansion of a T cell population by cell division as part of an immune response.

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

Any process that increases the rate, frequency or extent of macrophage chemotaxis. Macrophage chemotaxis is the movement of a macrophage in response to an external stimulus.

Any process that results in a change in state or activity of an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a lipopolysaccharide stimulus; lipopolysaccharide is a major component of the cell wall of gram-negative bacteria.

A series of molecular signals initiated by the binding of a tumor necrosis factor to a receptor on the surface of a cell, and ending with regulation of a downstream cellular process, e.g. transcription.

Any process that modulates the frequency, rate or extent of T cell proliferation.

Any process that activates or increases the frequency, rate or extent of the introduction of a phosphate group to a tyrosine residue of a STAT (Signal Transducer and Activator of Transcription) protein.

Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of an exogenous double-stranded RNA stimulus.

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

Any process that activates or increases the frequency, rate or extent of the inflammatory response.

Any process that activates or increases the frequency, rate or extent of activity of the transcription factor NF-kappaB.

Any process that increases the frequency, rate, or extent of monocyte chemotaxis.

Any process that increases the frequency, rate or extent of protein homodimerization, interacting selectively with an identical protein to form a homodimer.

Any process that stops, prevents or reduces the frequency, rate or extent of T-helper 17 cell lineage commitment.

Any process that modulates the frequency, rate or extent of dendritic cell chemotaxis.

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

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

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