T-Cell Memory: The Importance of Chemokine-Mediated Cell Attraction
A recent study demonstrates the involvement of certain chemokines in immune response initiation and CD8+ T-cell memory formation. These seminal findings broaden our understanding of the role of chemokines in adaptive immune processes.
متن کاملIdentification of a human CD8+ regulatory T cell subset that mediates suppression through the chemokine CC chemokine ligand 4.
Regulatory T cells (Treg) comprise multiple subsets and are important in controlling immunity and inflammation. However, the induction and mode of action of the various distinct Treg subsets remain ill defined, particularly in humans. Here, we describe a human CD8+ lymphocyte activation gene-3 (LAG-3)+CD25+FoxP3+ Treg subset, which suppresses T cells partly through the secretion of CC chemokine...
متن کاملStat3 phosphorylation mediates resistance of primary human T cells to regulatory T cell suppression.
Human autoimmune diseases are characterized by systemic T cell dysfunction, resulting in chronically activated Th1 and Th17 cells that are inadequately suppressed by regulatory T cells (Tregs). IL-6, which is overexpressed in tissue and serum of patients with autoimmune diseases, inhibits human Treg function. We sought to determine the mechanism for the antitolerogenic properties of IL-6 by exa...
متن کاملMonoclonal regulatory T cells provide insights into T cell suppression
Regulatory T cells (Tregs) have a crucial role in maintaining lymphocyte homeostasis. However an understanding of how Tregs function at a cellular and molecular level has not yet been fully elucidated. Here, we make use of a T cell receptor (TCR) transgenic, Rag(-/-) mouse expressing a Forkhead-Box-Protein P3 (Foxp3) transgene. This mouse provides a source of monoclonal CD4(+) Foxp3(+) T cells ...
