Fig. 1From: Amphotericin B suppresses M2 phenotypes and B7-H1 expression in macrophages to prevent Raji cell proliferationB7-H1 was expressed in tumor-associated macrophages (TAMs) of BL tissues. a and b Immunohistochemical analysis of B7-H1+ cells in tumor tissues (400×). B7-H1 positive TAMs that ingested apoptotic tumor cells are indicated by arrows. Scale 20 μm. c Double immunofluorescence staining showed a high degree of overlap expression with B7-H1 and CD68.
