Microenvironment in cutaneous melanomas: a gene expression profile study may explain the role of histological regression

Abstract
Specific subsets of T‐helper lymphocytes have been identified as associated with anergy and impairment of CD8+ immune response against cancer cells. In particular, the immune infiltrate of regressed melanoma has been proven to have lower counts of CD25+/CD4+, FOXP3+/CD4+ and PD1+/CD4+ lymphocytes compared to the non‐regressed ones.
