Transcriptional profiling of intestinal CD4(+) T cells in the neonatal and adult mice.

ABSTRACT: The adult small intestine contains more than half of the body's lymphocytes in order to maintain homeostasis with the commensal microbiota. Birth marks a transition of the intestine from a sterile to an increasingly colonized environment. The data described in this article are incremented into the work published by Torow et al. titled "Active suppression of intestinal CD4(+) TCR??(+) T lymphocyte maturation during the postnatal period" [1]. While most of the CD4 T cells found in the adult small intestine have an activated phenotype marked by expression of helper lineage specific genes neonatal lymphocytes exhibit a naïve phenotype. Further, direct comparison of neonatal CD4 T cells from the small intestine and the gut draining mesenteric lymph node (mLN) reveals a global transcriptional 'inactivity' of the small intestinal CD4 T cells. Here, we describe in more detail the experimental design, sample preparation and analysis that were performed to obtain and interpret the microarray data. The data set is publicly available through the Gene Expression Omnibus (GEO) database with accession number GSE60515, and the analysis and interpretation of these data are included in Torow et al. [1].

Project description:There is a great potential for the development of new cell replacement strategies based on adult human neural stem-like cells. However, little is known about the hierarchy of cells and the unique molecular properties of stem- and progenitor cells of the nervous system. Stem cells from the adult human brain can be propagated and expanded in vitro as free floating neurospheres that are capable of self-renewal and differentiation into all three cell types of the central nervous system. Here we report the first global gene expression study of adult human neural stem-like cells originating from five human subventricular zone biopsies (mean age 42, range 33-60). Compared to adult human brain tissue, we identified 1,189 genes that were significantly up- and down-regulated in adult human neural stem-like cells (1% false discovery rate). We found that adult human neural stem-like cells express stem cell markers and have reduced levels of markers that are typical of the mature cells in the nervous system. We report that the genes being highly expressed in adult human neural stem-like cells are associated with developmental processes and the extracellular region of the cell. The calcium signaling pathway and neuroactive ligand-receptor interactions are enriched among the most differentially regulated genes between adult human neural stem-like cells and adult human brain tissue. We confirmed the expression of 10 of the most up-regulated genes in adult human neural stem-like cells in an additional sample set that included adult human neural stem-like cells (n = 6), foetal human neural stem cells (n = 1) and human brain tissues (n = 12). The NGFR, SLITRK6 and KCNS3 receptors were further investigated by immunofluorescence and shown to be heterogeneously expressed in spheres. These receptors could potentially serve as new markers for the identification and characterisation of neural stem- and progenitor cells or as targets for manipulation of cellular fate.
