My research in the Pathology department is mainly focused on immunological aspects of B-cell lymphoma. I study interactions of tumor cells with the microenvironment, and signaling pathways in Hodgkin lymphoma and non-Hodgkin lymphomas.

The Epstein-Barr virus (EBV) can cause a wide variety of cancers upon infection of different cell types and induces a highly variable composition of the tumor microenvironment (TME). This TME consists of both innate and adaptive immune cells and is not merely an aspecific reaction to the tumor cells. In fact, latent EBV-infected tumor cells utilize several specific mechanisms to form and shape the TME to their own benefit. These mechanisms have been studied largely in the context of EBV+ Hodgkin lymphoma, undifferentiated nasopharyngeal carcinoma, and EBV+ gastric...

miRNAs are small noncoding RNAs involved in the posttranscriptional regulation of gene expression. Deregulated miRNA levels have been linked to Burkitt lymphoma (BL) pathogenesis. To date, the number of known pathogenesis-related miRNA-target gene interactions is limited. Here, we determined for the first time the miRNA targetomes of primary BL tumors and normal B cells. AG02-RNA immunoprecipitation of two frozen diagnostic BL tissue samples and three CD19(+) B-cell samples isolated from routinely removed tonsils showed distinct miRNA targetomes of BL and normal B cells. In contrast to normal B...

As an immune escape mechanism tumor cells may downregulate expression of Human Leukocyte Antigens (HLA). Loss of HLA class I and class II has been described in various subtypes of diffuse large B cell lymphoma (DLBCL), including the not otherwise specified (NOS) subgroup. 1,2 We analyzed HLA class I and class II expression in DLBCL not otherwise specified (NOS) to investigate whether there is an association between HLA expression, cell of origin (COO) and the recently reported FOXP1 expression in non-GCB DLBCL. 3 This article is protected by...
