Fig. 7From: B cell activating factor regulates periodontitis development by suppressing inflammatory responses in macrophagesBAFF knockdown promoted the macrophage phenotype switch from M1 to M2. a Representative immunofluorescence staining of M1 phenotype macrophages (iNOS+; red), BAFF knockdown reduced the expression of iNOS which was elevated by P. gingivalis LPS. b Representative immunofluorescence staining of M2 phenotype macrophages (CD206+; red). BAFF knockdown facilitated the expression of CD206 which was decreased by P. gingivalis LPS. The nuclei were stained with DAPI (blue).
