Induced collagen type-I secretion by hepatocytes of the melanoma liver metastasis is associated with a reduction in tumour-infiltrating lymphocytes
•Spatial analyses of melanoma liver metastasis show that adjacent normal hepatocytes have increased collagen-type I levels. | |
•Melanoma liver metastases tumour cells secrete enhanced levels of TNF-α to stimulate CXCR4/CXCL12 upregulation in adjacent normal hepatocytes. | |
•Activation of CXCR4 promotes AKT and NF-κB signalling pathways to promote collagen-type I secretion in adjacent normal hepatocytes. | |
•Elevated collagen levels were associated with reduced tumour-infiltrating lymphocytes |
