Regulatory T-cell compartmentalization and trafficking.
CD4(+)CD25(+)FOXP3(+) regulatory T cells (CD4(+) Treg cells) are thought to differentiate in the thymus and immigrate from the thymus to the periphery. Treg cells can regulate both acquired and innate immunity through multiple modes of suppression. The cross-talk between Treg cells and targeted cells, such as antigen-presenting cells (APCs) and T cells, is crucial for ensuring suppression by Tr...
متن کاملEffector and Regulatory T Cell Trafficking in Corneal Allograft Rejection
Corneal transplantation is among the most prevalent and successful forms of solid tissue transplantation in humans. Failure of corneal allograft is mainly due to immune-mediated destruction of the graft, a complex and highly coordinated process that involves elaborate interactions between cells of innate and adaptive immunity. The migration of immune cells to regional lymphoid tissues and to th...
متن کاملMigration matters: regulatory T-cell compartmentalization determines suppressive activity in vivo.
Regulatory T cells (Tregs) play a fundamental role in the suppression of different immune responses; however, compartments at which they exert suppressive functions in vivo are unknown. Although many groups have described the presence of Tregs within inflammatory sites, it has not been shown that inflamed tissues are, indeed, the sites of active suppression of ongoing immune reactions. Here, by...
متن کاملRegulatory T Cell Subtypes and TGF-β1 Gene Expression in Chronic Allograft Dysfunction
Background: Regulatory T cells have been suggested to have a protective role against acute rejection in allograft recipients. However, there is little information available about their contribution to chronic rejection process. The role of transforming growth factor-beta 1 (TGF- β1) as a profibrogenic and/or immunoregulatory cytokine in renal allografts is also controversial. Objectives: To eva...
متن کاملMicroenvironment and Immunology T-Cell Trafficking Facilitated by High Endothelial Venules Is Required for TumorControl after Regulatory T-Cell Depletion
The evolution of immune blockades in tumors limits successful antitumor immunity, but the mechanisms underlying this process are not fully understood. Depletion of regulatory T cells (Treg), a T-cell subset that dampens excessive inflammatory and autoreactive responses, can allow activation of tumor-specific T cells. However, cancer immunotherapy studies have shown that a persistent failure of ...
