Pleural Mesothelial Cells-Induced Monocytes to the Pleural Cavity through the Effect of C3 Lytic Products in Tuberculous Pleural Effusion

Figure 2

The concentrations of complement pyrolysis products were found higher in pleural effusion than in plasma from TPE patients. (a) Complement pyrolysis products, including C3a, C3b, C3d, C5a, and opsonin receptors (CR1 and CR3) were detected in human tuberculosis pleural biopsy samples by immunohistochemistry. (Original magnification, ×200) (n = 4). (b) Higher levels of complement pyrolysis products were found in pleural effusion than in plasma in TPE patients (n = 20). The concentrations of complement pyrolysis products in pleural fluid and plasma from TPE patients were measured by ELISA (n = 20).
