    摘要: Tolerogenic populations of dendritic cells are provided, where the dendritic cells are characterized by expression of select tissue-specific homing receptors including the chemokine receptors CCR9; or CMKLR1; or the integrin CD103. The dendritic cells may be conventional/myeloid or plasmacytoid dendritic cells. The cells may be isolated from lymphoid tissue, from blood, or from in vitro culture, e.g. bone marrow culture, etc. Methods are provided for their identification, isolation and targeting in immunotherapeutic interventions in suppressing inflammatory disorders including autoimmunity, transplantation responses and allergic diseases. In some embodiments dendritic cell populations are fixed to render them immunosuppressive, thus allowing the cells to be typed and banked for future use.

    摘要: Novel methods and compositions are provided for modulating homing of leukocytes, particularly lymphocytes, where the compounds are cross-reactive with Neu5Ac2-3Gal&bgr;1−X[Fuc&agr;1−y]GlcNAc, where one of x and y is three and the other is four. These compounds may be administered to a host associated with inflammation, to avoid the deleterious effects of leukocyte infiltration.

    摘要: Methods are provided to specifically modulate the trafficking of systemic memory T cells, particularly CD4+ T cells, without affecting naive T cells or intestinal memory T cells. It is shown that systemic memory T cells, which are characterized as CD45Ra−, and integrin &agr;4&bgr;7−, express high levels of CCR4. Ligands of CCR4, such as TARC or MDC, act as an adhesion trigger, wherein upon CCR4 binding, these cells undergo integrin-dependent arrest to the appropriate vascular receptor(s). This arrest acts to localize the cells at the target site. The methods of the invention manipulate this triggering, and CCR4 mediated chemotaxis, to affect the localization of T cells in targeted tissues. In one embodiment of the invention, the active agent is a CCR4 agonist, that acts to enhance T cell localization. In an alternative embodiment, the agent is an antagonist that blocks CCR4 biological activity. An advantage of the invention is the selectivity for systemic memory T cells, without affecting native T cells or intestinal memory T cells.
