Shouts, whispers and the kiss of death: directional secretion in T cells
&
Abstract
T cells use secreted soluble factors for highly specific intercellular communication and targeted cell killing. This specificity is achieved first through T cell receptor–mediated recognition of complexes of peptide and major histocompatibility complex displayed by appropriate antigen-presenting cells and then by the directed secretion of cytokines and lytic factors into the immunological synapse between the T cell and antigen-presenting cell. Studies have begun to probe the molecular basis for this synaptic secretion and have also shown that T cells release chemokines and certain inflammatory factors through a multidirectional pathway directed away from the synapse. Thus, the mode of secretion seems to be tailored to the intended function of the secreted molecule.
