Mean fluorescence intensity (MFI) of TREM-1, TREM-2, DAP12, HMGB1, RAGE, TLR-4 and TLR-2 using immunofluorescence staining in the biopsy samples of study subjects. A: MFI of target genes in omentum biopsy samples. B: MFI of target genes in subcutaneous biopsy samples. C: MFI of target genes in liver biopsy samples. MFI was calculated using Image-J software. The MFI levels of these targets in biopsy samples were compared between non-obese, obese non-diabetics and obese diabetics using One-way ANOVA for continuous variables. Data were shown as mean ± SD (N=5 non-obese; 24 obese non-diabetics; 22 obese diabetics); *P<0.05, **P<0.01, ***P<0.001, and ****P<0.0001.
