Özet
Non-Hodgkin lenfomalı 24 hastadan elde edilen periferik stem cell (PSC) ve kemik iliği ürünlerinin natural supresör (NS) hücre aktivitesi, IL-2 ile kültürden önce ve 5 gün IL-2 ile birlikte kültür yapılarak incelendi. Bu çalışmaya göre PSC ürünleri IL-2 ile stimüle edilmeden önce normal periferik kan lökositleri (PBL) ve kemik iliği (BM) ürünlerinden daha yüksek NS hücre aktivitesi gösterdi (p<0.001). İnterleukin-2 aktivasyonundan sonra, aktivasyon öncesine göre, PSC ürünlerinin NS hücre aktivitesi azalırken (p<0.05) BM’unki arttı (p<0.05). IL-2 ile kültürden sonra, normal donörlerden elde edilen PBL ile NHL’lı hastalardan elde edilen PSC ürünlerinin NS aktivitesi arasında istatistiki bakımdan önemli fark vardı (p<0.05). Bu sonuçlar, NHL’lı hastalarda NS aktivitesinin normalden daha yüksek olduğunu ve supresör hücrelerin varlığında NHL 7/ hastaların PSC lenfositlerinin IL-2 ’ye proliferatif cevap vermediğini göstermektedir.
The activity of natural suppressor (NS) cells of peripheral stem cell (PSC) and bone marrow (BM) products from 24 patients with non-Hodgkin's lymphoma (NHL) were examined both before and following 5 days co-incubation with IL-2. This study showed that in the PSC products prior to IL-2 incubation, NS activity had been higher than both normal peripheral blood leukocytes (PBL) and BM products (p<0.001). Following IL-2 activation, NS activity of PSC decreased (p<0.05) while BM products' NS activity increased (p<0.05) compared to culture in the absence of IL-2. NS activity levels were significantly different between PBL from normal donors and PSC from patients with NHL after culture with IL-2 (p<0.05). ^s these results show, NS activity is higher in PSC from NHL patients than that of controls and in the presence of suppressor cells, lymphocytes from the PSC products of NHL patients did not respond to IL-2 with an increase in proliferative capacity.
