Abstract The purpose of the study was to investigate the cytokine gene expression patterns and immunohistochemical characteristics of genitoanal warts in order to obtain a clue as to the immunological mechanisms possibly relevant for wart regression or persistence. We analysed surgically removed warts from 11 patients, 2 of whom were immunosuppressed. Lesions of five of the nine otherwise healthy individuals were additionally treated with intralesional interferon-γ (IFNγ) prior to surgery. Invasion of CD4 + T cells into the papillomas and HLA-DR and ICAM-1 expression on keratinocytes were found in two otherwise healthy patients and were intensified by intralesional IFNγ in four of five patients. The mRNA expression patterns in seven of eight nonrecurrent warts were compatible with a predominant TH1 or mixed TH1/TH2 cytokine profile. In contrast, in recalcitrant warts of three patients (one healthy, two immunocompromised) histological signs of immunoreactivity and TH1-like cytokine mRNA expression were not detected. In recurrent warts of a renal transplant patient, IL-4 and IL-5 mRNA expression was repeatedly found suggesting a predominant TH2 response. In conclusion, immunoreactivity to genitoanal warts such as T-cell infiltration, HLA-DR and ICAM-1 expression was associated with a predominant TH1 or mixed TH1/ TH2 cytokine mRNA expression profile.
