Summary

The antigenic properties of S-100β-positive human T-lymphocytes (S-100β+ T-cells) were investigated by a double immunostaining technique employing an indirect immunoperoxidase method for cytoplasmic S-100β subunit and an immunoalkaline phosphatase method for cell surface antigens detected by various monoclonal antibodies to human lymphocytes. S-100β+ T-cells recognized by their diffuse intracytoplasmic immunoperoxidase reaction, also expressed CD2, CD3, CD8 antigens demonstrated by surface blue alkaline phosphatase reactivity, but not CD4, CD1, CD25 (interleukin-2 receptor), or HLA-DR antigens. However, they displayed a blastic change to T-cell mitogens, such as Concanavalin A(Con-A) and PHA, followed by the expression of CD25 and HLA-DR antigens. Under normal conditions, S-100β+ T-cells comprised approximately 5–22.8% of CD8+ cells amongst human peripheral blood mononuclear cells.
