Spontaneous and interleukin 2 induced secretion of tumour necrosis factor and gamma interferon following autologous marrow transplantation or chemotherapy

Br J Haematol. 1989 Jun;72(2):122-6. doi: 10.1111/j.1365-2141.1989.tb07671.x.


Culture of lymphocytes from allograft recipients or from normal donors with Interleukin 2 (IL2) induces high levels of gamma-interferon (gamma IFN) and tumour necrosis factor (TNF) secretion. We now show that production of these two cytokines can also be increased after autologous bone marrow transplantation (BMT) and induced following chemotherapy for haematological malignancy. These effects occur even though the regenerating IL2 responsive lymphocytes in this context have previously been extensively exposed to cytotoxic agents. IL2 induced secretion of gamma-IFN and TNF is higher in autograft recipients than in patients treated by chemotherapy alone. This effect may be related to differences in the phenotypic profile between recovering lymphocytes in the two groups and to an increased degree of prior in vivo lymphocyte activation in the autologous bone marrow transplant recipients. In both groups of patients, IL2 acts on CD3+ T cells and on CD16+ NK cells so that depletion of either subset incompletely abrogates IL2 dependent gamma-IFN secretion. As both TNF and gamma-IFN possess anti-leukaemic and anti-infective activity, enhancement of their secretion by IL2 infusion after autologous bone marrow transplant and induction after chemotherapy may be of therapeutic benefit.
