CXCR3 May Help Regulate the Inflammatory Response in Acute Lung Injury via a Pathway Modulated by IL-10 Secreted by CD8 + CD122+ Regulatory T Cells

The aim of this study is to investigate the role of CXCR3 and IL-10 in lipopolysaccharide (LPS)-induced acute lung injury (ALI). ALI was induced by LPS injection (10 mg/kg) via the tail vein in C57BL/6 mice. Mice were sacrificed after 2 or 12 h to examine the levels of inflammatory cytokines in bron...

description The aim of this study is to investigate the role of CXCR3 and IL-10 in lipopolysaccharide (LPS)-induced acute lung injury (ALI). ALI was induced by LPS injection (10 mg/kg) via the tail vein in C57BL/6 mice. Mice were sacrificed after 2 or 12 h to examine the levels of inflammatory cytokines in bronchoalveolar lavage fluid (BALF) and histopathologic assessments. At 12 h after LPS injection, mice exhibited more severe lung infiltration by CD8+ T cell and less infiltration by CD8+CD122+ regulatory T cells than at 2 h after LPS challenge or in the control (mice not exposed to LPS). At 12 h, IFN-γ, CXCR3, and CXCL10 were significantly higher in the lungs. IL-10 in the lungs was significantly lower. CXCR3 may help to recruit CD8+ T cells and promotes IFN-γ and CXCL10 release. Such effects could be inhibited by IL-10 secreted by CD8+CD122+ regulatory T cells.
