Brief Summary

Natural Killer (NK) cells play a unique role during innate immune responses as they are able to recognize and eliminate, without specific sensitization, tumors, microbe-infected cells as well as allogeneic cells.In a first time, we will characterize the tissue distribution, the phenotype and the effector functions of NK cells present in the human healthy skin.

Outcome Measures

Primary Outcomes (1)

  • In a first time, we will characterize the tissue distribution, the phenotype and the effector functions of NK cells present in the human healthy skin.

    12 months

Secondary Outcomes (1)

  • To determine whether the eventual modifications detected in skin pathologies are correlated to qualitative/ quantitative alterations of NK cell subsets present in the peripheral blood.

    12 months
