lüll Mechanisms and consequences of dendritic cell migration Alvarez D; Vollmann EH; von Andrian UHImmunity 2008[Sep]; 29 (3): 325-42Dendritic cells (DCs) are critical for adaptive immunity and tolerance. Most DCs are strategically positioned as immune sentinels poised to respond to invading pathogens in tissues throughout the body. Differentiated DCs and their precursors also circulate in blood and can get rapidly recruited to sites of challenge. Within peripheral tissues, DCs collect antigenic material and then traffic to secondary lymphoid organs, where they communicate with lymphocytes to orchestrate adaptive immune responses. Hence, the migration and accurate positioning of DCs is indispensable for immune surveillance. Here, we review the molecular traffic signals that govern the migration of DCs throughout their life cycle.|*Cell Movement[MESH]|*Chemotaxis[MESH]|Animals[MESH]|Chemotactic Factors/immunology/metabolism[MESH]|Cytokines/immunology/*metabolism[MESH]|Dendritic Cells/*immunology/physiology[MESH]|Humans[MESH]|Lymphoid Tissue/*immunology[MESH]|Receptors, Chemokine/immunology/metabolism[MESH]|Signal Transduction[MESH]|Spleen/cytology/immunology[MESH] |
