Human Retroviruses and Soluble CD30 Levels of Patients

Shigeki Takemoto

Human T-cell leukemia virus type 1 infection makes CD4+ T cells transformed into leukemic cells, whereas human immunodeficiency virus make them destroyed. Interestingly, activation of CD30 led to the induction of apoptotic death of anaplastic large cell lymphoma cells, while Hodgkin’s lymphoma cells, which constitutively express NF-κB, were not susceptible to CD30-induced apoptosis. Such a pleiotropic effect of CD30 signaling is dependent on cell type, B-cell or T-cell, and probably different activation status of NF-κB, constitutive or inducible.Accordingly, CD30 triggering may be responsible for the enhanced retroviral replication and T cell death under the influence of T cell activation and/or NF-κB activation status, showing high levels of sCD30.
