T Cell Trafficking. Trafficking of antigen-specific T cells into the central nervous system CNS is an important initiating step in inflammation in the brain. Migration of naïve T cells from the blood to these sites follows the general adhesion and signaling steps of cell-trafficking namely selectin-mediated rolling chemokine-triggered activation and integrin-dependent arrest of T cells. In spite of the extensive knowledge about the role of adhesion molecules in T cell migration across peripheral vessels the mechanism of the entry of antigen-specific T cells into the CNS is not known. Integrins and chemokines are critical for immune cell recruitment to tissue under homeostatic and pathological conditions1 The heterodimeric integrin α4β7 expressed on T cells specifies the recruitment of T cells to the intestinal mucosa upon its interaction with its ligand MAdCAM-11 Intestinal specificity is imprinted in T cells via upregulation of α4β7 integrin upon their interaction.

Live cell imaging techniques to study T cell trafficking across the blood-brain barrier in vitro and in vivo. The central nervous system CNS is an immunologically privileged site to which access for circulating immune cells is tightly controlled by the endothelial blood-brain barrier BBB located in CNS microvessels. Molecular mechanisms of CD8 T cell trafficking and localization. Autoimmunity is triggered by trafficking of self-reactive T cells into tissues. The dynamic remodeling of the actin cytoskeleton is a key component of cell locomotion and membrane trafficking. Previous studies have suggested that the T cell immune response of tumor-bearing patients is significantly lower than that of healthy people and the principal reason for this is lymphocytopenia which is caused by repeated cycles of chemotherapy.
The trafficking of T cells involves complex interactions between T cells and endothelial cells EC.
CCR7 is thus a master regulator of T cell trafficking in lymph nodes as it promotes T cell entry through HEVs as well as the motility compartmentalization and retention of T cells within lymph.

Cytotoxic CD8 T cells are potent mediators of host protection against disease due to their ability to directly kill cells infected with intracellular pathogens and produce inflammatory cytokines at the site of infection. In summary activated T cells traffic to the site of inflammation in the LP in DSS-induced colitis Fig. Autoimmunity is triggered by trafficking of self-reactive T cells into tissues. T-cell-receptor triggering and the delivery of co-stimulation are essential events leading to T cell expansion differentiation and effector function. Trafficking of antigen-specific T cells into the central nervous system CNS is an important initiating step in inflammation in the brain.

The central nervous system CNS is an immunologically privileged site to which access for circulating immune cells is tightly controlled by the endothelial blood-brain barrier BBB located in CNS microvessels. This process requires an initial transitory attachment to the endothelium followed by rolling firm adhesion and T-cell activation on the endothelial surface and finally extravasation through the blood vessel wall to the site of infection 1. To fully achieve this objective naïve CD8 T cells must. In spite of the extensive knowledge about the role of adhesion molecules in T cell migration across peripheral vessels the mechanism of the entry of antigen-specific T cells into the CNS is not known. In addition to detailed experimental procedures the interested reader will find informative introductory chapters on the relevance of T-Cell trafficking in thymic population and maturation traffic through secondary lymphoid organs during physiological resolving inflammation and during immune responses as well as T-Cell trafficking in chronic inflammatory diseases.
