Increased PD-L1 Restricts Liver Injury in Nonalcoholic Fatty Liver Disease

Figure 1

PD-L1 expression levels in liver samples and FFA-treated LO2 cells. (a–d) PD-L1 expression and CD8+ T cells in the liver tissues determined by immunohistochemistry. (e) Intracellular lipid accumulation after FFA treatment (0.8 mM) for 24 hour measured by Oil Red staining. (f–i) Expression levels of PD-L1 detected by qRT-PCR, western blot, and immunofluorescence. .
