34023785-4	2021	By using a metabolite library screen, we showed that pyridoxal (PL) significantly suppresses PD-L1 expression.	Pyridoxal	53-62	CD274 molecule	Sus scrofa	93-98	
34023785-4	2021	By using a metabolite library screen, we showed that pyridoxal (PL) significantly suppresses PD-L1 expression.	Pyridoxal	64-66	CD274 molecule	Sus scrofa	93-98	
34023785-6	2021	Functionally, PL enhances T cell killing activity by blocking the PD-1/PD-L1 signaling pathway.	Pyridoxal	14-16	CD274 molecule	Sus scrofa	71-76	
34023785-7	2021	Thus, we have identified PL as an inhibitor of PD-L1, which provides a feasible option for combination immunotherapy.	Pyridoxal	25-27	CD274 molecule	Sus scrofa	47-52
