Complement system was activated in human tuberculous pleurisy. (a) Immunohistochemistry staining images of three complement activation pathways, including early markers in the activation pathway (C1q, factor B factor P, and MBL), the final product (MAC) a regulatory protein (CD46), effector molecules (C3 and C5) in human pleural biopsy samples from TPE patients (original magnification, ×200) (n = 4). (b) The concentrations of complement components in pleural fluid and plasma from TPE patients were measured by ELISA (n = 20).
