Any process that stops, prevents, or reduces the rate of T cell mediated cytotoxicity.

Any process that stops, prevents, or reduces the frequency, rate or extent of the cytokine mediated signaling pathway.

Any process that stops, prevents, or reduces the frequency, rate or extent of protein kinase activity.

The process of removing one or more phosphoric residues from a protein.

The process of removing one or more phosphoric (ester or anhydride) residues from a molecule.

The process in which a precursor cell type acquires characteristics of a more mature T-cell. A T cell is a type of lymphocyte whose definin characteristic is the expression of a T cell receptor complex.

The expansion of a B cell population by cell division. Follows B cell activation.

Any process that activates or increases the rate or extent of T cell proliferation.

A series of molecular signals initiated by the cross-linking of an antigen receptor on a B cell.

Any process that activates or increases the frequency, rate or extent of signaling pathways initiated by the cross-linking of an antigen receptor on a B- or T cell.

The process in which calcium ions sequestered in the endoplasmic reticulum, Golgi apparatus or mitochondria are released into the cytosolic compartment.

Reactions triggered in response to the presence of a virus that act to protect the cell or organism.

Any process that modulates the rate or extent of progression through the cell cycle.

A series of molecular signals initiated by the cross-linking of an antigen receptor on a T cell.

The process in which precursor cell type acquires the specialized features of a hematopoietic progenitor cell, a class of cell types including myeloid progenitor cells and lymphoid progenitor cells.

The chemical reactions and pathways resulting in the formation of immunoglobulin.

Any process that stops, prevents, or reduces the frequency, rate or extent of protein kinase activity.

The disassembly of adhesions at the front and rear of a migrating cell. At the leading edge, adhesion disassembly accompanies the formation of new protrusions; at the cell rear, it promotes tail retraction.

A series of molecular signals initiated by activation of a receptor on the surface of a cell. The pathway begins with binding of an extracellular ligand to a cell surface receptor, or for receptors that signal in the absence of a ligand, by ligand-withdrawal or the activity of a constitutively active receptor. The pathway ends with regulation of a downstream cellular process, e.g. transcription.

Any process that activates or increases the rate or extent of B cell proliferation.

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

The cell cycle process by which a cell commits to entering the next cell cycle phase.

Any process that activates or increases the frequency, rate or extent of protein kinase activity.

The process whose specific outcome is the progression of the bone marrow over time, from its formation to the mature structure.

The process whose specific outcome is the progression of the stem cell over time, from its formation to the mature structure. Cell development does not include the steps involved in committing a cell to its specific fate.

A series of molecular signals initiated by the cross-linking of an antigen receptor on a T cell.

A series of molecular signals initiated by the cross-linking of an antigen receptor on a T cell.

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

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

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.

Small region on the surface of a cell that anchors the cell to the extracellular matrix and that forms a point of termination of actin filaments.

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

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.

The lipid bilayer surrounding a secretory granule.

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.
