A rise in body temperature above the normal, often as a response to infection.

The change in morphology and behavior of alpha-beta T cells resulting from exposure to a mitogen or to an antigen to which they have been primed.

A conditioned aversion to a specific chemical compound as a result of that compound being coupled with a noxious stimulus.

The process whereby a relatively unspecialized hemopoietic stem cell acquires the specialized features of an alpha-beta T cell.

An acute behavioral change resulting from a perceived external threat.

The rapid expansion of an alpha-beta T cell population by cell division.

regulation of alpha-beta T cell activation

regulation of alpha-beta T-lymphocyte activation

Any process that modulates the frequency, rate or extent of alpha-beta T cell activation.

Interacting selectively with a G-protein-coupled receptor.

The chemical reactions involving chemokines, any of a subgroup of cytokines which act primarily on hemopoietic cells in acute and inflammatory processes and other immunoregulatory functions.

positive regulation of alpha-beta T cell activation

positive regulation of alpha-beta T-lymphocyte activation

Any process that activates or increases the rate of alpha-beta T cell activation.

Catalysis of the reaction: CMP-N-acetylneuraminate + glycano-1,3-(N-acetyl-alpha-D-galactosaminyl)-glycoprotein = CMP + glycano-(2,6-alpha-N-acetylneuraminyl)-(N-acetyl-D-galactosaminyl)-glycoprotein.

The alteration of cellular processes due to exposure to lowered oxygen tension.

regulation of alpha-beta T cell differentiation

regulation of alpha-beta T-lymphocyte differentiation

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

Cell migration that is accomplished by extension and retraction of a pseudopodium.

positive regulation of alpha-beta T cell differentiation

positive regulation of alpha-beta T-lymphocyte differentiation

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

Catalysis of the reaction: phosphatidylinositol-4,5-bisphosphate + H2O = phosphatidyl inositol-4-phosphate + phosphate.
