Özet
Fitohemaglutinin (PHA), genellikle bir T lenfosit mitojenidir. CD4+ helper/inducer T lenfositlerine, CD8' suppressor/cytotoxic T lenfositlerine göre daha fazla stimulator etki yapar. Bu çalışmada, biz normal periferik kan lökositleri (PBL) ile otolog kemik iliği (BM) ve granulosit-monosit koloni stîmulan faktör (GM-CSF) ile mobilize edilmiş periferik stem cell (PSC) ürünlerinin PHA 'e verdikleri mitojenik cevapların farklı olup olmadığını araştırdık. Non-Hodgkin lenfomalı 24 hastadan kemik iliği ve periferik stem cell ürünleri toplandı ve IL-2 ile 5 gün kültür yapılmadan önce ve yapıldıktan sonra PHA hücre proliferasyon cevabı incelendi. Hem PSC hem de BM hücrelerinin PHA proliferatif cevapları anlamlı şekilde normal PBL 'den düşüktü (p
Abstract
Phytohemagglutinin (PHA) is principally a T lymphocyte mitogen, producing a greater stimulatory effect* on CD4+ helper/inducer T lymphocytes than on CD8+ suppressor/cytotoxic T cells. In this study, investigated if there are differences in the mitogenic response to PHA between autologous bone marrow " (BM) and granulocyte-monocyte colony stimulating factor (GM-CSF)-mobilized peripheral stem cell (PSC) products as well as to normal peripheral blood leukocytes (PBL). BM and PSC products from 24 patients with non-Hodgkin's lymphoma (NHL) were collected and assays of cell proliferation in response to PHA were performed both before and following 5 days co-incubation with IL^2. The proliferative response to PHA by cells from both PSC and BM products were significantly lower than normal PBL (p
