Two T-lymphocyte subsets develop in the thymus which differ in the expression of glycoproteins on their cell surface. About 60% of the circulating T cells express the glycoprotein T4, while about 30% have the glycoprotein T8. T4 and T8 cells can be determined in the peripheral blood or various organs with monoclonal antibodies. T4 and T8 cells differ in their antigen recognition, have different functions, and can cause various pathohistological changes. T4 cells recognize the antigen in association with the HLA-D/DR/DP determinants. Upon antigenic stimulation they liberate various factors and initiate and amplify an immune response (T4 = helper/inducer T-cells). They can also be cytotoxic and are mediating effector functions via macrophage activation. T8 cells recognize the antigen in association with HLA-A/B/C determinants. They exert their cytotoxic or suppressive effector functions mainly in viral infections. The T4 or T8 cell-mediated pathohistological changes are discussed in the light of the well studied T-cell infiltrations in lepra lepromatosa or lepra tuberculosa. The T4/T8 cell dyscrasia in the peripheral blood, described in a variety of infectious, autoimmune or immunodeficiency diseases, may be due to enhanced proliferation, selective sequestration, reduced production or the elimination of a subset. T-cell subset analysis in joints, bronchial lavages and tissues has clarified the pathomechanism in a variety of autoimmune diseases, although the etiology remains obscure. For example, in rheumatoid arthritis, multiple sclerosis, and sarcoidosis, a T4 cell-mediated reaction with macrophage activation can be found. T4/T8 cell analysis may also be of value in dissecting heterogenous diseases, e.g. systemic lupus erythematosus. Of value is also the additional demonstration of membrane components reflecting T-cell activation (IL-2 receptor or DR-antigen expression) which serves to identify the activated T-cell subset in peripheral blood. Finally, T4/T8 cell analysis can be helpful in deciding treatment, as the T-cell subsets have a different sensitivity to immunosuppressive drugs.

Previous studies have shown the involvement of the immune response in the progression of human uterine cervix cancer. The aim of this study was to determine the expression of Interleukin-2 (IL-2), IL-2 receptor (IL-2R) and Interleukin 10 (IL-10) in different grades of cervical intraepithelial neoplasias of the exocervix (CIN 1, 2 and 3), and its relationship with the serum cytokine profiles and human papilomavirus (HPV) infection status. Indirect immunofluorescence was used to study the expression of IL-2, IL-2R and IL-10 in human cervical samples from 50 patients and 9 normal controls. Serum IL-2, IL-2R and IL-10 were measured by ELISA and HPV DNA and HPV types were identified by PCR. Increased number of IL-2, IL-2R and IL-10 positive cells were observed in the cervix from patients with CIN, associated with the grades of dysplasia. A significant correlation was observed between IL-2 and IL-2R (p>0.0001), IL-2 and IL-10 (p>0.0001), as well as IL-10 and IL-2R (p>0.0001). Twenty percent of patients were HPV positive and 84% of those patients were tissue cytokine positive. These results suggest that IL-2, IL-2R and IL-10 tissue expression may play a role in the development of cervical intraepithelial dysplasias.
