N2 - Carcinoma of the cervix is causally related to infection with the human papillomavirus (HPV), and T cells play a pivotal role in the immune response of the host to rid itself of HPV infection. Therefore, we assessed the T-cell function of women with HPV-related cervical neoplasia against a superantigen, Staphylococcus enterotoxin B (SEB). Each woman provided a cervical brush specimen for HPV DNA testing and Papanicolaou (Pap) smears for the staging of cervical lesions. They also provided a blood specimen for determination of the ability of CD4+ T and CD8+ T cells to synthesize Th1 (interleukin-2 [IL-2], gamma interferon [IFN-γ], and tumor necrosis factor alpha [TNF-α]) and Th2 (IL-10) cytokines in response to activation with SEB. Compared with control subjects with self-attested negative Pap smears, women with high-grade squamous intraepithelial lesions (HSIL) had significantly lower percentages of activated CD4+ T cells that produced IL-2 (P = 0.045), IFN-γ (P = 0.040), and TNF-α (P = 0.015) and a significantly lower percentage of activated CD8+ T cells that produced IL-2 (P < 0.01). These data indicate that women with HPV-related cervical HSIL show a decrease in Th1 cytokine production by activated CD4 + T cells and suggested that compromised T-helper functions may negatively impact the function of cytotoxic CD8+ T cells.
