Illumina HiSeq 2500
Description
We performed single-cell RNA-seq on CD4 T cells isolated from the tonsils of one healthy donor. We used the 10x chromium technology. Overall design: Tonsil CD4 T cells were enriched by negative selection using magnetic beads. Cell populations (CXCR5+PD-1low T cells, CXCR5+PD-1int T cells and CXCR5+PD-1high T cells ) were further isolated by cell sorting. Cellular suspensions (3500 cells) were loaded on a 10X Chromium instrument (10X Genomics) according to manufacturer's protocol.

Description
We performed single-cell RNA-seq on CD14+ cells isolated from the tonsils of one healthy donor. We used the 10x chromium technology. Overall design: Tonsil phagocytes were prepared by centrifugation on a Ficoll gradient. Dendritic cells and macrophages were enriched by negative selection using magnetic beads. Cell populations were further isolated by cell sorting. Cellular suspensions (3500 cells) were loaded on a 10X Chromium instrument (10X Genomics) according to manufacturer's protocol.

Affymetrix Human Gene 1.1 ST Array (hugene11st), Illumina Genome Analyzer IIx
Description
Memory T cells are primed for rapid responses to antigen; however, the molecular mechanisms responsible for priming remain incompletely defined. CpG methylation in promoters is an epigenetic modification, which regulates gene transcription. Using targeted bisulfite sequencing, we examined methylation of 2100 genes (56,000 CpG) mapped by deep sequencing to T cell activation in human nave and memory CD4 T cells. 466 CpGs (132 genes) displayed differential methylation between nave and memory cells. 21 genes exhibited both differential methylation and gene expression before activation, linking promoter DNA methylation states to gene regulation; 6 genes encode proteins closely studied in T cells while 15 genes represent novel targets for further study. 39 genes exhibited reduced methylation in memory cells coupled with increased gene expression with activation compared to nave cells, revealing specific genes more rapidly expressed in memory compared to nave cells and potentially regulated by DNA methylation. These findings define a DNA methylation signature unique to memory CD4 T cells and correlated with activation-induced gene expression.

CpG methylation in promoters is an epigenetic modification, which regulates gene transcription. Using targeted bisulfite sequencing, we examined methylation of 2100 genes (56,000 CpG) mapped by deep sequencing to T cell activation in human naïve and memory CD4 T cells. 466 CpGs (132 genes) displayed differential methylation between naïve and memory cells. 21 genes exhibited both differential methylation and gene expression before activation, linking promoter DNA methylation states to gene regulation; 6 genes encode proteins closely studied in T cells while 15 genes represent novel targets for further study. 39 genes exhibited reduced methylation in memory cells coupled with increased gene expression with activation compared to naïve cells, revealing specific genes more rapidly expressed in memory compared to naïve cells and potentially regulated by DNA methylation. These findings define a DNA methylation signature unique to memory CD4 T cells and correlated with activation-induced gene expression. Overall design: RNA sequencing of primary human naïve and memory CD4 T cells at rest and 48 hours post-activation.

Description
Host pathways mediating changes in immune states elicited by intestinal microbial colonization are incompletely characterized. Here we describe alterations of the host immune state induced by colonization of germ-free zebrafish larvae with an intestinal microbial community or single bacterial species. We show that microbiota-induced changes in intestinal leukocyte subsets and whole-body host gene expression are dependent on the innate immune adaptor gene myd88. Similar patterns of gene expression are elicited by colonization with conventional microbiome, as well as mono-colonization with two different zebrafish commensal bacterial strains. By studying loss-of-function myd88 mutants, we find that colonization suppresses Myd88 at the mRNA level. Tlr2 is essential for microbiota-induced effects on myd88 transcription and intestinal immune cell composition. Overall design: Zebrafish embryos were sterilized to generate germ-free groups. Transcriptomic responses in germ-free embryos were were assessed relative to colonized embryos, either colonized by complex and in characterized microbial communities (Conventionalozation) or by specefic single commensal bacterial species (monoassociation, Exiguobacterium/Chryseobacterium)

Description
ZIP-3 has been shown to repress the mitochondrial-UPR response. To identify genes repressed by ZIP-3, we compared transcript profiles from wildtype, atfs-1(tm4919) and zip-3(gk3164) worms raised on control RNAi or spg-7 RNAi Overall design: RNA samples were prepared from wild-type(wt) and zip-3(gk3164)(mutant) worms fed either control RNAi or spg-7 RNAi. Worms were synchronized by bleaching, raised on NGM plates seeded with control RNAi or spg-7 RNAi till L4 stage and then harvested. Each experiment was performed in triplicate indicated as 1,2 and 3.

Description
ZIP-3 has been shown to repress the mitochondrial-UPR genes and immune response during P. aeruginosa infection. To identify genes repressed by ZIP-3, we compared transcript profiles from wildtype and zip-3(gk3164) worms raised on P. aeruginosa or E. coli. Overall design: RNA samples were prepared from wild-type(wt) and zip-3(gk3164)(mutant) worms fed either E. coli or P. aeruginosa. Worms were synchronized by bleaching, starved on empty NGM plates for 48h, transferred to E. coli or P. aeruginosa seeded NGM plates for 18h and then harvested. Each experiment was performed in triplicate indicated as 1,2 and 3.
