The process in which a signal is passed on to downstream components within the cell, which become activated themselves to further propagate the signal and finally trigger a change in the function or state of the cell.

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

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

Any process that activates or increases the frequency, rate or extent of alpha-beta T cell differentiation.

Any process that activates or increases the frequency, rate or extent of alpha-beta T cell differentiation.

Any process that activates or increases the frequency, rate or extent of alpha-beta T cell proliferation.

The phosphorylation by a protein of one or more of its own amino acid residues (cis-autophosphorylation), or residues on an identical protein (trans-autophosphorylation).

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.

The adhesion of one T cell to one or more other T cells via adhesion molecules.

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.

An area of close contact between a lymphocyte (T-, B-, or natural killer cell) and a target cell formed through the clustering of particular signaling and adhesion molecules and their associated membrane rafts on both the lymphocyte and the target cell and facilitating activation of the lymphocyte, transfer of membrane from the target cell to the lymphocyte, and in some situations killing of the target cell through release of secretory granules and/or death-pathway ligand-receptor interaction.

A protein complex that contains a disulfide-linked heterodimer of T cell receptor (TCR) chains, which are members of the immunoglobulin superfamily, and mediates antigen recognition, ultimately resulting in T cell activation. The TCR heterodimer is associated with the CD3 complex, which consists of the nonpolymorphic polypeptides gamma, delta, epsilon, zeta, and, in some cases, eta (an RNA splice variant of zeta) or Fc epsilon chains.
