IFN-γ and STAT1 are required for efficient induction of CXC chemokine receptor 3 (CXCR3) on CD4+ but not CD8+ T cells

Abstract
To the editor: The CXC chemokine receptor 3 (CXCR3) regulates migration and function of T cells during inflammation. Resting T cells express low levels of CXCR3 but they up-regulate CXCR3 upon activation. Several studies suggest that T helper 1 (Th1)/Th2-associated cytokines regulate levels of
