Abstract

 


The immune response to interleukin-2 (IL-2) differs between autologous bone marrow (BM) and granulocyte-monocyte colony stimulating factor (GM-CSF) mobilized peripheral stem cell (PSC) products as well as compared to normal peripheral blood leukocytes (PBL). Stem cell products from 24 patients with non-Hodgkin’s lymphoma (NHL) were examined both before and following 5 days co-incubation with IL-2, and the cell proliferation in response to IL-2 were examined. These studies show that the IL-2 stimulated proliferative response of PSC was not different than observed with normal PBL, but there was statistically significant decrease between not only PBL and BM but also PSC and BM (p=0.0136 and p=0.0179, respectively). As these results show, ex vivo threat of PSC with IL-2 before PSC transplantation is capable of to increase defective-lymphocyte function. Therefore, the use of PSC transplantation as compared to BM transplantation for hematologic reconstitution is superior. [Journal of Turgut Özal Medical Center 1996;3(2):75-79]
