摘要
CXCL12 expression was significantly lower in tumor samples than in corresponding normal samples.CXCL12 expression was significantly positively related to the infiltration levels of T cells,dendritic cells(DCs),immature DCs,cytotoxic cells,Tfh cells,mast cells,B cells,Th1 cells,natural killer(NK)cells,pDCs,neutrophils,and T helper cells(Spearman correlation coefficient>0.5,P<0.001)and negatively correlated with the infiltration level of NK CD56bright cells.In addition,pancreatic hTERT-HPNE cells treated with three diverse CXCL12 isoforms exhibited changes mainly in the regulation of the epithelialmesenchymal transition activation pathway.
