Summary (written by the submitters)
Serotonergic neurons have multiple roles, including regulating mood and behavior1,2, yet it remains unclear which of these phenotypes are caused by serotonin produced by the central versus the peripheral nervous system. Neuronal serotonin is produced by the enzyme tryptophan hydroxylase 2 (Tph2)3. Mice that lack Tph2 exhibit decreased gut motility4 and several behavioral disorders, including decreased anxiety-like behavior and increased aggression5.

To clarify the specific role of peripheral serotonergic circuits, here we engineered mice with intact Tph2 in central neurons but lacking Tph2 in peripheral neurons (Tph2fl/fl; Hand2-Cre). We discovered that PSN contribute to gut motility and are important in the control of anxiety-like behavior but do not contribute to impulsive aggression. Thus, central and peripheral serotonergic neurons have different roles in behavioral regulation. Intriguingly, animals lacking peripheral neuronal Tph2 had deficiencies in enteric immune cells, including reduced abundance of dendritic cells (DC) and IgA+ B cells in the small intestine and elevated susceptibility to oral Salmonella infection. Mechanistic studies suggest that serotonin produced by PSN promotes activation of DC through the 5-HT7 receptor, thereby facilitating DC-mediated differentiation of IgA+ B cells. Our findings highlight the importance of serotonin produced by peripheral neurons for control of behavior and gut defense and suggest that these circuits could be valuable targets for therapeutics.

Download · which file do I need?

Direct links to NCBI and ENA, no account and no request form. Pick by what you want to do: take the small processed table to look, the supplementary files to re-analyse, or the original raw data to start over.

1 · Just have a look

Processed table

The series matrix: one table of values per sample as the submitters processed it. The smallest download, and it opens in Excel or R. Start here to see what the data look like.

2 · Re-analyse it

Supplementary files

The count tables and other files the authors uploaded. Take only the samples you need, or the whole study as GSE227338_RAW.tar (it can run to tens of gigabytes).

3 · Start from the raw reads

Raw sequencing reads

The original FASTQ files, straight from the sequencer, held at ENA. Large, and you align them yourself, so only choose this if you need to re-process the study from scratch.

What the files usually look like: For RNA-seq the counts are usually a table among the supplementary files (look for 'counts', 'expression', 'FPKM' or 'TPM' in the file name). The series matrix of a sequencing study is sometimes nearly empty.

Also filed as BioProject PRJNA944674 and SRA study SRP427273. Searching any of these in the dataset finder brings you back here.
