Hepatocellular carcinoma (HCC) is associated with elevated soluble CD40 levels in our previous study. Here we aimed to investigate CD40's role in liver tumor progression. We examined CD40 levels in HCC patient tissues and various HCC cell lines, studying their interaction with CD4+ T cells. RNA sequencing analysis was performed to explore the mechanisms of CD40 induction. Poorly differentiated HCC tumour tissues exhibited high membrane-bound CD40 (mCD40) expression, in contrast to non-tumour areas. Poorly differentiated HCC cell lines showed high expression of mCD40 with low CD40 promoter methylation which were opposite of well-differentiated ones...
