PG - 127-34 AB - Since Hodgkin and Reed-Sternberg (HRS) cells of Hodgkin lymphoma (HL) generally have immunoglobulin gene rearrangements, they are considered to be of B-cell origin. One of the characteristics of HRS cells is a prominent production of various cytokines and chemokines. Cytokine production is generally driven by expression of T-cell transcription factors (TFs). Only limited information is available on the expression of T-cell TFs in HL. Expression of four T-cell TFs and the target cytokine spectrum of these TFs were analyzed in six HL and three large B-cell lymphoma (LBCL) cell lines using quantitative PCR. ERM expression was observed in all HL and LBCL cell lines. Out of HL cell lines, T-bet was expressed in five, GATA-3 in four, and c-Maf in two cell lines. Immunohistochemistry in HL tissues revealed that in 11 of 12 (92%) of the classical HL cases HRS cells were GATA-3 and/or T-bet positive. In three of six cases of nodular lymphocyte predominance type of HL, the neoplastic cells were T-bet positive. Overall, the T-cell TF and cytokine profiles of the HL cell lines showed a considerable degree of consistency. The expression of T-cell TFs may explain the production of various cytokines by HL cell lines and HRS cells.
