Preferential Usage of TCR-V17 by Peripheral and Cutaneous T Cells in Nickel-Induced Contact Dermatitis1 Lioba Bu¨dinger,*† Nicole Neuser,* Uwe Totzke,‡ Hans F. Merk,* and Michael Hertl2*§ Nickel (Ni) is one of the most common contact sensitizers in man, and Ni-induced contact dermatitis is considered as a model of hapten-induced delayed type hypersensitivity. Previous studies indicated that Ni-reactive T cells derived from Ni-allergic indi- viduals preferentially express distinct TCR-V chains. However, data on the TCR-V repertoire of Ni-responsive T cells are not consistent. Therefore, the aim of this study was to identify the TCR-V receptors of Ni-responsive peripheral and cutaneous T cells in a cohort of 17 donors with Ni-induced contact dermatitis in comparison with those of 6 healthy controls. Peripheral NiSO4- responsive T lymphocytes showed a significant overexpression of TCR-V17 and the frequency of TCR-V17؉ T cells correlated significantly with the in vitro reactivity of PBMC to NiSO4. In addition, the cutaneous infiltrate of Ni-induced patch test reactions ؉  Downloaded from consisted primarily of V 17 T cells. The majority of patch test-derived NiSO4-responsive T cells of three allergic donors were  ؉  TCR-V 17 , whereas patch test-derived NiSO4 unresponsive T cells of four additional donors did not express TCR-V 17. Skin-derived Ni-responsive T cell lines from three donors uniformly secreted the Th2 cytokine, IL-5, but no IFN-␥ or IL-10. These in vitro and in vivo findings strongly suggest that T cells with a restricted TCR-V repertoire, i.e., V17, predominate in NiSO4-induced contact dermatitis and may be crucial in the effector phase of Ni hypersensitivity.

Skin biopsies were taken from cessing-dependent and -independent pathways, as shown for other six Ni-allergic patients and two nonallergic controls 24 h after performing an additional epicutaneous patch test with NiSO4. This particular time haptens (4, 6–7).
