The cell vaccination is a new strategy in treatment of infectious diseases and cancers. In this study, we have generated monocyte-derived dendritic cells of lymphoma patient's peripheral blood mononuclear cells then; these cells were used as vaccine in lymphoma patients. We generated dendritic cell vaccine from lymphoma patient's blood monocytes with human interleukin-4, granulocyte monocyte colony stimulating factor and then, antigen-primed Dcs were administrated subcutaneously close to the inguinal lymph nodes after maturation of dendritic cells. After 7 days, we analyzed immune response in lymphoma patients with determining of LDH, Beta 2 Microglobulin, CD4+T cell percent, CD8+ Tcell percent and Tumor size before and after vaccination. Furthermore, phenotypic and functional analysis of dendritic cells was performed using anti CD83-FITC monoclonal antibodies. Before vaccination, the mean ± SD of LDH was 530.62±140.65 but after vaccination it was 459±109.45 that significantly different between experimental groups (P=0.002). In addition, the CD8+ T cells percentage significantly different between two groups (P=0.002). We concluded that the use of dendritic cell probably is one of the suitable noninvasive treatments for lymphoma patients that they have not response to chemical drugs. https://acta.tums.ac.ir/index.php/acta/article/view/4446 https://acta.tums.ac.ir/index.php/acta/article/download/4446/4570
