Activation of lymphocytes in vitro for immunotherapy of patients with melanoma

Abstract

This article describes a method for activating lymphocytes isolated from the peripheral blood of melanoma patients and cultured in a medium supplemented with IL‑2 and IL‑15. It was shown that in these terms, lymphocytes have an increased proliferative and activation potential. The combination of cytokines has a positive effect on cytotoxicity, viability and the expression of activation markers (CD38, CD69, CD25, HLA-DR and NKG2D) on NK- and T-lymphocyte, and may be recommended for the culture of lymphocytes in melanoma patients for the purpose of adoptive immunotherapy.
