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

Figure 14

Proportion of CD3⁺CD8⁺ T lymphocytes after coculture of A-MSCs with or without inhibitor. The proportion of CD3⁺CD8⁺ T lymphocytes was significantly lower in the TLR4 inhibitor group at each concentration than the control group. While the concentrations in the TLR3 and TLR4 coinhibition groups were significantly lower than those in the control group, there was no significant difference from the TLR4 group.
