| Research Abstract |
CCR4 is a chemokine receptor selectively expressed by Th2 cells, regulatory T cells, and skin-homing T cells. We have shown a potent ther apeutic effect of a small molecule CCR4 inhibitor on Th2-induced airway inflammation in mice. We have also shown that CCR4 and its ligand MDC/CCL22 mediate immunosuppressive interactions of dendritic cells and regulatory T cells in mesenteric lymphonodes. Furthermore, human oncogenic viruses such as EBV and HTLV-1 commonly induce expression of MDC/CCL22 in infected host cells to attract Th2 cells and regulatory T cells for immunoevasion and virus propagation.
