Affymetrix Human Gene 1.0 ST Array (hugene10st)
Description
Primary human macrophages with a HIF-1alpha or HIF-2alpha knockdown were pretreated with IL-10 for 16h and afterwards for 4h additionaly under hypoxi (1% O2), RNA was isolated usind the Qiagen RNAeasy Kit and cDNA synthesis wos done using Ambion WT Expression Kit. Expression was compared to si control under control conditions.

Description
The relevance of DNA-dependent poly-ADP ribose production for neuronal differentiation of adult stem- and progenitor cells from the SVZ was studied. To identify genes whose up- or downregulation during neuronal differentiation requires the activity of poly-ADP-Ribosylase (PARP) 1 or 2, SVZ-derived adult neurosphere cultures were differentiated in the presence or absence of Olaparib.

Description
In a supervised principal component analysis, histiocytes from TCHRBCL were most closely related to epithelioid cells from NLPHL, with both types of cells expressing genes related to proinflammatory and regulatory macrophage activity.

Description
Several studies have described a crosstalk between the tumour cells of cHL, the Hodgkin- and Reed-Sternberg (HRS) cells, and cancer-associated fibroblasts (CAF). However, to date a deep molecular characterization of these fibroblasts is lacking. Aim of the present study therefore was a comprehensive characterization of these fibroblasts.

Description
Nodular lymphocyte predominant Hodgkin lymphoma (NLPHL) is an indolent lymphoma, but can transform into diffuse large B cell lymphoma (DLBCL), showing a more aggressive clinical behavior. Little is known about these cases on the molecular level. Therefore, the aim of the present study was to characterize DLBCL transformed from NLPHL (LP-DLBCL) by gene expression profiling (GEP). GEP revealed an inflammatory signature pinpointing to a specific host response. In a coculture model resembling this host response, DEV tumor cells showed an impaired growth behavior. Mechanisms involved in the reduced tumor cell proliferation included a downregulation of MYC and its target genes. Lack of MYC expression was also confirmed in 12/16 LP-DLBCL by immunohistochemistry. Furthermore, CD274/PD-L1 was upregulated in tumor cells after coculture with T cells or monocytes and its expression was validated in 12/19 cases of LP-DLBCL. Thereby, our data provide new insights into the pathogenesis of LP-DLBCL and a concrete explanation of the relatively low tumor cell content. Moreover, our results suggest that treatment of these patients with checkpoint inhibitors may enhance an already ongoing host response in these patients.

Description
Hodgkin's lymphoma (HL) is one of the most frequent hematological malignancies. Due to its extraordinary composition, few tumor cells surrounded by a reactive infiltrate, HL can be seen as an ideal model system for research focusing on tumor immunology. In fact, the tumor cells of HL, so called Hodgkin/Reed-Sternberg (HRS) cells attract CD4+ T cells, which then build rosettes with the HRS cells. HRS cells further modulate the tumor microenvironment with the help of CD4+ T cells to avoid tumor rejection. Here, we mimicked this scenario using compatible CD4+ T cells receiveing data of profound interactions for the first time, as former studies were performed with allogeneic donors. Finally, we genetically retargeted compatible CD4+ T cells to kill HRS cells.
