| Abstract | In the last years one rises importance of costimulatory molecules in immune response in leukemias. Aim of the study was to assess lymphocytes T function in children with acute lymphoblastic leukemia during remission induction on the grounds of chosen costimulatory and activatory molecules expression. To assess percentages of lymphocytes subpopulations we used tricolor flow cytometry. Results: 1. In the moment of diagnosis and remission induction we noted higher percentages of lymphocytes T with adhesion molecule ICAM-1; 2. During remission induction we observed lower percentage values of lymphocytes T with CD38 coexpression; 3. In the end of remission induction rised the percentage values of lymphocytes T helper with IL-2 receptor expression; 4. In the group of patients with fever/infection we observed higher percentage of activated lymphocytes T (CD3-HLA-DR) comparing to non-infected patients. Summarizing, we suggest lymphocytes T activation during appearance and remission induction of acute lymphoblastic leukemia in children. This confirms participation of cellular immunity in leukemic process. |
