    • Hodgkin's disease (HD) tumours are characterized by the presence of few tumour cells, the Hodgkin and Reed-Sternberg (HRS) cells, surrounded by a large amount of non-neoplastic cells. The role of this cell infiltrate for the development of HD is not known. CD30, belonging to the tumour necrosis factor receptor superfamily, is highly expressed on HRS cells and believed to be involved in tumourigenesis and tumour progression. Tumour samples from 42 patients were immunohistochemically double-stained for tryptase, a mast cell-specific proteinase and CD30 ligand (CD30L). Tryptase-positive mast cells were present in all tumours. Of these cells, 50% expressed CD30L and 66% of the CD30L-positive cells were mast cells. CD30L mRNA in in vitro developed normal mast cells and malignant human and murine mast cell lines was detected using reverse transcription polymerase chain reaction. CD30L protein expressed on human mast cells was detected using flow cytometry. In a co-culture assay, the human mast cell line HMC-1 stimulated thymidine uptake in HRS cell lines, and the stimulation could be blocked using CD30L-specific monoclonal antibodies. In conclusion, mast cells are present in HD tumours and are the predominant CD30L-expressing cells. CD30L-CD30 interaction is a pathway by which mast cells may stimulate DNA synthesis in HRS cells.

  • IL-9 expression contributes to the cellular composition in Hodgkin lymphoma

    • OBJECTIVES:The presence of numerous mast cells or eosinophils in Hodgkin lymphoma (HL) tumours have both been described as negative prognostic factors. One cytokine related to HL is interleukin-9 (IL-9) and it is known to affect both mast cells and eosinophils. The aim of this study was to explore if the expression of IL-9 correlates to the presence of these inflammatory cells in HL tumours.METHODS:In 131 HL biopsies, immunostainings for IL-9 and IL-9 receptor (IL-9R) were performed. The same material was previously stained for mast cells and eosinophils. These data were correlated to clinical and survival data from all patients.RESULTS:Fifty-three percent of cases were positive for IL-9 and 19% were positive for IL-9R in the cytoplasm of the tumour cells. The IL-9 positive patients had more eosinophils (P = 0.002) and mast cells (P = 0.02) in their tumours, more often a nodular sclerosis histology (P < 0.0001), a higher white-blood-cell count (P = 0.006) and a higher erythrocyte sedimentation rate (P = 0.003) at the time of diagnosis.CONCLUSIONS:IL-9 expression is related to the histology, clinical picture and the presence of eosinophils and mast cells in HL. These results indicate that IL-9 is an important part of the cytokine network and inflammatory infiltrate in HL.

  • Mast cell infiltration is a favourable prognostic factor in diffuse large B-cell lymphoma
  • 2007
  • Ingår i: British Journal of Haematology. - : Wiley. - 0007-1048 .- 1365-2141. ; 138:1, s. 68-71

    • Previous studies indicate that the inflammatory response in diffuse large B-cell lymphomas (DLBCL) is important for the clinical outcome. Mast cells are key regulators in this response; we investigated whether the number of tryptase-positive mast cells is correlated with clinical outcome. Patients with many mast cells had a significantly better event-free survival (EFS) compared to those with few mast cells (P < 0.03 in both germinal centre (GC) and non-GC DLBCL. This supports the idea that the infiltration of mast cells is a reflection of the host inflammatory response and is related to a favourable outcome.

  • Mast cell infiltration correlates with poor prognosis in Hodgkin's lymphoma
  • 2002
  • Ingår i: British Journal of Haematology. - : Wiley. - 0007-1048 .- 1365-2141. ; 119:1, s. 122-124

    • Hodgkin's lymphoma (HL) is characterized by a few Hodgkin, Reed-Sternberg cells (HRS) surrounded by benign cells. We recently reported that mast cells were the predominant CD30L-positive cells in HL tumours, and that they activate HRS in vitro through CD30L-CD30 interaction. Here, we investigated the clinical importance of mast cell infiltration in the tumours of 123 patients. Tumour specimens were stained with a mast-cell-specific antibody that detects tryptase. Mast cells were detected in virtually every case and increasing numbers of mast cells correlated to nodular sclerosis histology (P = 0.008). Patients with higher mast cell infiltration had a worse relapse-free survival (P = 0.01).
