Although PMCs are known to exert multiple immune functions, their role in pleurisy remains unclear.Methods: Pleurisy model was induced by intrapleural injection of Mycobacterium bovis bacillus Calmette-Guerin (BCG) into wild-type (WT) C57BL/6 mice. The pleural cavity was washed with Phosphate Buffered Saline (PBS) to get the immune cells. Flow cytometry was performed to identify the characteristics of the target cells.Results: We found that IFN-γ prompts PMCs to act a summon role for the recruitment of inflammatory cells in pleurisy model. Our data showed that CD4+ T cells were the main producer of IFN-γ in the pleurisy model, and IFN-γ stimulated PMCs to recruit immune cells into the pleural cavity through the CXCL10-CXCR3 axis. In addition, IFN-γ can reshape PMCs to display macrophage-like polarization. These results revealed some new immune roles of PMCs in pleurisy.Conclusion: In a mouse model of pleurisy, IFN-γ, which is mainly derived from CD4+ T cells, promoted PMCs to recruit of immune cells into the pleural cavity and exhibited macrophage-like polarization.Keywords: IFN-γ, pleurisy, pleural mesothelial cells, macrophages |
