Description
We purified five subsets representing the main stages of human precursor-B-cell differentiation and CD34+lin- cord blood cells. The immunoglobulin (Ig) gene rearrangement status was determined using TaqMan quantitative PCR and GeneScan analysis. To gain more insight in the networks of genes that initiate and/or regulate the different types of Ig gene rearrangements, we analyzed their gene expression profiles by correlating the initiation of Ig gene rearrangements with specific upregulation of transcription factors. In addition to previously described transcription factors, we identified 16 candidate genes involved in initiation and/or regulation of Ig gene rearrangements.

Description
To gain more insight into initiation and regulation of T cell receptor (TCR) gene rearrangement during human T cell development, we analyzed TCR gene rearrangements by quantitative PCR analysis in nine consecutive T-cell developmental stages, including CD34+ lin- cord blood cells as a reference. The same stages were used for gene expression profiling using DNA microarrays.

Description
Tumor progression is associated with an immunosuppressive microenvironment that consists of several elements, such as regulatory T cells, type 2 macrophages and myeloid-derived suppressor cells. Here, we identify for the first time a BDCA1+CD14+ population of immunosuppressive cells that resides both in the blood and tumor of melanoma patients. We demonstrated that the presence of these cells in dendritic cell (DC)-based anti-tumor vaccines significantly suppresses CD4+ T cells in an antigen-specific manner. In an attempt to reveal the mechanism of this suppressive activity, we noticed that BDCA1+CD14+ cells express elevated levels of the check-point molecule PD-L1, which thereby hinders T cell proliferation. Importantly, although this suppressive BDCA1+CD14+ population expresses markers of both BDCA1+ DCs and monocytes, functional, transcriptome and proteome analyses clearly revealed that they comprise a unique population of cells that is exploited by tumors to evade immunity. Thus, targeting these cells may improve the efficacy of cancer immunotherapy.

Description
Human NK cells were sorted into CD56dim and CD56bright NK cell subpopulations. In order to define characteristics of both populations gene profiling was performed using Affymetrix arrays U133a and U133B.

Description
We describe GC-Tfr, a population of CD25 negative Foxp3 positive CXCR5hiPD1hiBCL6hi T-follicular regulatory cells that preferentially localise in the germinal centers. Male C57BL/6 Foxp3-DTR-GFP reporter mice were vaccinated with NP-Ova in Alum and 7 days later cells sorted before RNA-sequencing. Analysis revealed that GC-Tfr have a gene expression pattern equidistant between Tregs and Tfh, but fundamentally retain their suppressive characteristics as regulatory cells.

Description
To determine the regulatory T cell-specific transcriptional regulation, we compared gene expression profiles of regulatory T, na?ve T and activated conventional T cells. As activated T cells, we prepared two sets of them: conventional T cells stimulated with anti CD3 and CD28 antibodies, and those stimulated by PMA and ionomycin. Comparison of these cell types should elucidate activation-related and regulatory T cell lineage-specific transcriptional programs.
