Fel d 1-derived T cell peptide therapy induces recruitment of CD4+ CD25+; CD4+ interferon-gamma+ T helper type 1 cells to sites of allergen-induced late-phase skin reactions in cat-allergic subjects.


BACKGROUND Specific immunotherapy with whole allergen extracts is associated with local accumulation of IFN-gamma+ and CD25+ cells indicating recruitment of activated T-helper type 1 (Th1) and/or T regulatory cells. We have studied allergen-induced, late-phase skin biopsies before and after T cell peptide therapy for evidence of alterations in the pattern… (More)
