Affymetrix Mouse Gene 1.0 ST Array (mogene10st)
Description
Within the human gut reside diverse microbes coexisting with the host in a mutually advantageous relationship. We comprehensively identified the modulatory effects of phylogenetically diverse human gut microbes on the murine intestinal transcriptome. Gene-expression profiles were generated from the whole-tissue intestinal RNA of mice colonized with various single microbial strains. The selection of microbe-specific effects, from the transcriptional response, yielded only a small number of transcripts, indicating that symbiotic microbes have only limited effects on the gut transcriptome overall. Moreover, none of these microbe-specific transcripts was uniformly induced by all microbes. Interestingly, these responsive transcripts were induced by some microbes but repressed by others, suggesting different microbes can have diametrically opposed consequences.

Description
Here we analyzed the transcriptional profile of S-IECs sorted from GF and monocolonized mice (C. histolyticum and B. adolescentis), as well as SPF mice colonized with SFB or not.

NextSeq 500
Description
We analyzed the transcriptional profile of small-intestinal lamina propria (SI-LP) CD4+ T cells isolated from germ-free and mice monocolonized with Bifidobacterium adolescentis, SFB, and Nexabiotic (a 23-strain, Th17-inducing, probiotic mix). Overall design: CD4+ T cells were double-sorted from mice directly into lysis buffer.

Description
The colonic lamina propria contains a distinct population of Foxp3+ T regulatory cells (Tregs) that modulate responses to commensal microbes. Analysis of gene expression revealed that the transcriptome of colonic Tregs is distinct from splenic and other tissue Tregs. Ror and Helios in colonic Tregs mark distinct populations: Ror+Helios- or Ror-Helios+ Tregs. We uncovered an unanticipated role for Ror, a transcription factor generally considered to be antagonistic to Foxp3. Ror in colonic Tregs accounts for a small but specific part of the colon-specific Treg signature.
