Supplementary Figure S4 from Repolarization of Immunosuppressive Macrophages by Targeting SLAMF7-Regulated CCL2 Signaling Sensitizes Hepatocellular Carcinoma to Immunotherapy

(A) Representative IHC staining images showing the expressions of SLAMF7, p-STAT1, and p-STAT3 in HCC samples from Fudan LCI cohort. Scale bar: 200 μm (left) and 20 μm (right). (B) Representative immunofluorescence staining (left) and the infiltration levels (right) of exhausted T cells (CD8+ PD-1+ TCF1-) in HCC tumors with high and low SLAMF7 protein expression in the Fudan LCI cohort. Scale bar: 20μm. *P<0.05, Student’s t test.
