Description
The goal of this study was to identify the molecular characteristics and putative markers distinguishing IL-10eGFP+CD138hi and IL-10eGFP-CD138hi plasmocytes. To this end, IL-10eGFP B-green mice were challenged intravenously with Salmonella typhimurium (strain SL7207, 10e7 CFU), and IL-10eGFP+CD138hi as well as IL-10eGFP-CD138hi plasmocytes were isolated from the spleen on the next day. For this, single cell suspensions were prepared, cells were treated with Fc block (10 g/ml, anti-CD16/CD32, clone 2.4G2), and then stained with an antibody against CD138 conjugated to PE (1/400; from BD Pharmingen) followed by incubation with anti-PE microbeads (Miltenyi Biotech). CD138+ cells were then enriched on Automacs (Miltenyi Biotech) using the program possel_d2. Cells were then stained with anti-CD19-PerCP, anti-CD138-PE, and antibodies against CD11b, CD11c, and TCR conjugated to APC as a dump channel to exclude possible contaminants. DAPI was added to exclude dead cells. Live IL-10eGFP+CD138hi and IL-10eGFP-CD138hi cells were subsequently isolated on a cell sorter. The purity of the samples was always above 98%. This led to the identification of LAG-3 as a cell surface receptor specifically expressed on IL-10eGFP+CD138hi cells but not on IL-10eGFP-CD138hi cells.

Description
CNS autoimmunity is induced by autoreactive T cells reactive against CNS antigen. However how these T cells become able to transgress the blood brain barrier is not CNS autoimmunity is induced by autoreactive T cells reactive against CNS antigen. Here a gene expression profile of the pathogenic T cells in different functional states was performed.

Description
Androgens are essential for sexual development and reproduction. However, androgen regulation in health and disease is poorly understood. Previously, we showed that human adrenocortical H295R cells grown under starvation conditions acquire a hyperandrogenic steroid profile with changes in steroid metabolizing enzymes HSD3B2 and CYP17A1 essential for androgen production. Furthermore, we have shown that metformin inhibits androgen production of steroidogenic H295R cells and inhibits complex I activity of the respriatory chain. Therefore, to search for underlying mechanisms regulting androgen production and to understand the basic biology of androgens, we have characterized the gene expression profile of H295R cells grown under normal growth conditions, serum starvation (hyperandrogenic) growth conditions as well as after metformin treatment (hypoandrogenic).

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.
