Unique Identifier : AIDSLINE MED/94147372 AB The influence of progesterone at the physiological concentration on normal donor and malignant patient peripheral blood lymphocytes incubated with interleukin 2 (IL-2) was investigated. Analysis of the phenotypes of IL-2-activated lymphocytes revealed that there was a difference in the positive rates of CD4+ and CD8+ cells between normal donors and patients with malignancies. Activated lymphocytes of normal adults older than 35 years of age consisted of 60-100% of CD4+ cells and 0-30% of CD8+ cells. Donors younger than 35 years of age showed a positive rate of CD4+ cells, ranging from 0-100%, while CD8+ cells were between 0-60%. However, in patients with malignancies both CD4+ and CD(8+)-activated lymphocytes diffused from 0-100%. Activated lymphocytes of most patients were CD8+ cell dominant, which reversed the CD4+/CD8+ ratio. Almost all patients at clinical stage IV showed a deviation of the positive rates of CD4+ and CD8+ cells from the normal range. It is an open question whether the prognosis of the patients with normal positive rates of CD(4+)- and CD(8+)-activated lymphocytes is favorable or not.
