Foxp3, a transcription factor of the forkhead/winged helix family, plays a unique role in the transcriptional control of regulatory CD4+CD25+ T (Treg) cells. The identification of potential target genes associated with the regulatory phenotype and the characterization of combinatorial interactions of transcription factors (TF) in promoter regions in genes regulated by Foxp3 has become important to understand the transcriptional control of Treg cells.

View SamplesMice deficient in MBD2 (Mbd2-/-) were treated with 2% dextran sulfate sodium or normal drinking water for 6 continuous days. A single cell suspension of colon lamina propria and epithelium was isolated, with monocytes (CD11b+ Ly6CHi, MHC-II+/-), macrophages (CD11b+ Ly6C-MHC-II+), cDC2s (CD11b- CD11c+ CD103+) and epithelial cells (CD45- EpCAM+) purified by FACS.

View SamplesT follicular helper cells (TFH) are heterogenic population of CD4+ T cells, expressing CXCR5+ and PD-1+ on their surface. Their role is linked to supporting formation of germinal centres (GC) and these cells are thought to express high levels of PD-1 marker. Two models of immunisation were used to investigate the role of PD-1 low TFH. In Salmonella enterica infection high frequency of T follicular helper cells expressing low levels of PD-1 surface molecule are observed within first week of infection but GC do not appear until much a later stage (week 7-8). Sheep red blood cell immunisation (SRBC) gives rise to both TFH and GC B cells within first week of response and these TFH express low to high level of PD-1 molecule.

View SamplesTo identify transcription factors that control dendritic cell development, we performed transcriptional profiling analyses of the murine hematopoietic progenitor cell line FDCP-mix that is permissive for DC differentiation in the presence of GMCSF.We reasoned that GM-CSF modulates a defined set of decisive transcription factors governing DC differentiation during the first few days.
