Scientific summary


Characterization of Natural Killer cell subsets infiltrating human melanoma

For several solid tumors resistant to conventional treatments which include malignant melanoma, immunotherapy remains an alternative of choice. To manipulate the immune response against the tumors with favorable results, it is important to understand the interactions between tumor cells and cytotoxic immune cells. We focus our interest on the study of Natural Killer cells because recent experimental data indicate that they are involved in the antitumor response. The role of NK cells in immunosurveillance of human tumors remains poorly documented and the mechanisms of tumor escape are not well understood. Globally, tumor infiltrating NK (NK-TIL) have not been well characterized. From our recent data, we hypothesized that NK-TIL could influence the natural progression and/or response to melanoma treatment (either conventional or perhaps with targeted therapies).

Our main objectives are 1- to characterize the phenotype and functional capacities of NK-TIL, by ex vivo analyses from primitive and metastatic lymph nodes melanoma; 2- to study the distribution of NK cells in situ to establish a correlation between NK infiltrate and tumor prognosis.

This program will bring new and original findings on the local immune response in melanoma and more specifically will characterize the NK-TIL along tumor progression. This research program may result in new immunotherapeutic strategies to target NK cells and tumor cells for a more efficient treatment.
