Pyridoxal-5-Phosphate Promotes Immunomodulatory Function of Adipose-Derived Mesenchymal Stem Cells through Indoleamine 2,3-Dioxygenase-1 and TLR4/NF-κB Pathway

Figure 6

Western blot detection of immune-related proteins TLRs, IDO, and NF-κB stimulated by different PLP concentrations. TLR3, TLR4, NF-κB, and IDO had the highest protein expression levels, while TLR6 protein expression was the lowest at 50 ng/mL PLP.
