The lipid bilayer surrounding the platelet dense granule.

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

Interacting selectively with a low density lipoprotein receptor.

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.

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.

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.

positive regulation of alpha-beta T cell activation
