NKp30 isoforms and NKp46 transcripts in metastatic melanoma patients: Unique NKp30 pattern in rare melanoma patients with favorable evolution.

ABSTRACT: Given the NK cell-based immunosurveillance of melanoma, we investigated the prognostic value of NKp46 transcript and NKp30 isoform (NKp30A, NKp30B and NKp30C) profiling in blood of 187 melanoma patients including 13 long survivors (LS), metastatic patients that have controlled the disease. Compared to healthy volunteers (HV), patients had reduced amounts of transcripts of the three NKp30 isoforms (NKp30 A, B and C) but similar ratios between NKp30 isoforms (ΔAB, ΔAC, ΔBC). Stratification of patients according to disease stage showed higher NKp30C and lower NKp46 transcripts in stage IV patients. Furthermore, patients with previous history of conventional chemotherapy displayed reduced NKp30A transcripts. The expression levels of NKp30 isoforms failed to predict survival from sampling of pa
