Abstract
Peripheral blood mononuclear cells (PBMC) collected from subjects prior to treatment and post-treatment with a vaccine composed of leishmania antigens were analyzed by flow cytometry. Upon analysis, it was noticed that lymphocyte subsets (LS) varied with psoriasis area and severity index (PASI) range (1–10, 11–20 and 21–72). Pre-treatment absolute values of gated LS were as follows. CD4+CD8−, CD3+CD8−, CD8+CD3+, CD8+CD4− and CD8+HLA− decreased in PBMC as PASI increased, suggesting migration from the blood to the skin. Contrary to the previous finding, the following LS, CD8+HLA+ and HLA+CD8−, and membrane surface immunoglobulin IgA+, IgD+ and IgM+ increased in PBMC as PASI increased, suggesting activation and proliferation by unknown antigens. After treatment with seven doses of AS100, the following LS, CD3+CD8−, CD8+CD3−, HLA+CD8−, CD8+HLA+ and CD4+CD8−, increased, while CD8+CD3+, CD8+HLA−, CD19 and CD8+CD4+ decreased in PBMC.
