Flow Cytometric Analysis of Leishmania Reactive CD4+/CD8+ Lymphocyte Proliferation in Cutaneous Leishmaniasis |

| چکیده انگلیسی مقاله |
Background: Determination of the division history of T cells in vitro is helpful in the study of effector mechanisms against infections. Technique described here uses the intracellular fluorescent label carboxyfluorescein diacetate succinimidyl ester (CFSE) to monitor the proliferation. Methods: In a cross sectional study, blood samples were collected from 7 volunteers with history of cutaneous leishmaniasis (CL) and one healthy control from endemic areas in Isfahan province who referred to the Center for Research and Training in Skin Diseases and Leprosy (CRTSDL), then CD4+/CD8+ lymphocytes and CD14+ monocytes were isolated from peripheral blood mononuclear cells (PBMC) using mAbs and magnetic nanoparticles. CFSE labeled CD4+ or CD8+ lymphocytes cultured with autologous monocytes in the presence of PHA, SLA, live Leishmania major or as control without stimulation. Cells were harvested after 7 days and were analyzed using flow cytometry. Results: Five consecutive divisions were monitored separately. Stimulation of CD4+ or CD8+ lymphocytes from CL subjects with SLA showed a significant difference in proliferation comparing with unstimulated cells (P Conclusion: The percentage of divided cells might be calculated separately in each division. The cells remained active following CFSE staining and there is possibility of functional analysis simultaneously. |
