A series of molecular signals initiated by the binding of interleukin-15 to a receptor on the surface of a cell, and ending with regulation of a downstream cellular process, e.g. transcription.

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

Any process that modulates the frequency, rate or extent of gene expression. Gene expression is the process in which a gene's coding sequence is converted into a mature gene product or products (proteins or RNA). This includes the production of an RNA transcript as well as any processing to produce a mature RNA product or an mRNA or circRNA (for protein-coding genes) and the translation of that mRNA or circRNA into protein. Protein maturation is included when required to form an active form of a product from an inactive precursor form.

Any process that activates or increases the frequency, rate or extent of differentiation of CD4-positive, CD25-positive, alpha-beta regulatory T cells.

Any process that activates or increases the frequency, rate or extent of T cell differentiation in the thymus.

A series of molecular signals initiated by the binding of interleukin-15 to a receptor on the surface of a cell, and ending with regulation of a downstream cellular process, e.g. transcription.

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

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

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

An intracellular protein kinase cascade containing at least a MAPK, a MAPKK and a MAP3K. The cascade can also contain an additional tiers: the upstream MAP4K. The kinases in each tier phosphorylate and activate the kinase in the downstream tier to transmit a signal within a cell.

Any immune system process that functions in the calibrated response of an organism to a potential internal or invasive threat.

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.

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

The process in which a relatively unspecialized precursor cell acquires specialized features of a lymphocyte. A lymphocyte is a leukocyte commonly found in the blood and lymph that has the characteristics of a large nucleus, a neutral staining cytoplasm, and prominent heterochromatin.

A series of molecular signals initiated by the binding of interleukin-15 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 interleukin-15 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 interleukin-2 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 interleukin-7 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 interleukin-9 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 interleukin-21 to a receptor on the surface of a cell, and ending with regulation of a downstream cellular process, e.g. transcription.

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

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

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

The leaflet of the plasma membrane that faces away from the cytoplasm and any proteins embedded or anchored in it or attached to its surface.

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

A vacuole to which materials ingested by endocytosis are delivered.

The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.

The component of the plasma 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.

The leaflet of the plasma membrane that faces away from the cytoplasm and any proteins embedded or anchored in it or attached to its surface.

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.
