Post-translational sulfation of tyrosines affects the affinity and binding of at least some chemokine receptors to their ligand(s) and has been hypothesized to be a feature in all chemokine receptors. This binding initiates downstream signaling cascades. By this mechanism, tyrosine sulfation can influence the cells involved in acute and chronic events of cellular immunity. These events include ...
The migration patterns of naive and activated T cells are associated with the expression of distinct sets of chemokine receptors, but the molecular basis for this regulation is unknown. Here we identify Krupple-like factor 2 (KLF2) as a key transcriptional factor needed to prevent naive T cells from expressing inflammatory chemokine receptors and acquiring the migration patterns of activated T ...
The question of why certain types of tumors often metastasize to the same organs has intrigued scientists for over a century. In 1889, Paget put forth the ‘‘seed and soil’’ concept that cancer cells (seed) spread in a nonrandom fashion to distant target organs where they are drawn based on a conducive microenvironmental milieu (soil; ref. 1). A second concept that has been around for sometime i...
Natural killer T (NKT) cells are important regulators of the immune system, but their trafficking machinery, including expression of chemokine receptors, has been poorly defined. Unlike other conventional T-cell populations, we show that most NKT cells express receptors for extralymphoid tissue or inflammationrelated chemokines (CCR2, CCR5, and CXCR3), while few NKT cells express lymphoid tissu...
BACKGROUND AND PURPOSE The C-X-C chemokine receptors 3 (CXCR3) and C-X-C chemokine receptors 4 (CXCR4) are involved in various autoimmune diseases and cancers. Small antagonists have previously been shown to cross-inhibit chemokine binding to CXCR4, CC chemokine receptors 2 (CCR2) and 5 (CCR5) heteromers. We investigated whether CXCR3 and CXCR4 can form heteromeric complexes and the binding cha...
I n our first review on chemokines (1), we suggested that blockade of the IL-8 receptor or inhibition of IL-8 gene expression could be a new principle for designing antiin-flammatory agents. The unexpected growth of the chemo-kine family and consequent redundancy of the system eventually made it clear that acting at the level of chemo-kine gene expression was rather hopeless, but the idea of in...
