Show moreCutaneous and uveal melanoma are malignant tumours with no treatment available once the metastases occur. Despite both melanomas are highly immunogenic, and often despite the presence of potent anti-tumour immune cells in patients__ blood, in more than 95% of patients, tumour growth remains unaffected. Hereby we investigate the mechanisms that help melanomas to escape from the spontaneous or activated by vaccination cytotoxicity of T lymphocytes and discuss the impact of local microenvironment created by melanoma, focusing on the role of immunomodulatory dendritic cells.
