CD8+ T Cells in Hodgkin’s Disease Tumor Tissue Are a Polyclonal Population with Limited Clonal Expansion but Little Evidence of Selection by Antigen

Willenbrock, Klaus, Roers, Axel, Blöhbaum, Birgit, Rajewsky, Klaus, Hansmann, Martin-Leo

A minor component (about 25%) of lymphocytes in Hodgkin’s disease (HD) are CD8+ T cells. It is unclear whether the presence of these cells reflects an antitumor cytotoxic response. The goal of the...
