Introduction/objectives: Sjogren's syndrome (SS) is a chronic inflammatory and difficult-to-treat autoimmune disease. Timosaponin AIII (TAIII), a plant-derived steroidal saponin, effectively inhibits cell proliferation, induces apoptosis, and exhibits anti-inflammatory properties. This study explored the mechanisms of action of TAIII in SS treatment by studying gut microbiota and short-chain fatty acids (SCFAs) using fecal metabolomics.

The gut microbiota plays key roles in host health by shaping the host immune responses through their metabolites, like indole derivatives from tryptophan. However, the direct role of these indole derivatives in macrophage fate decision and the underlying mechanism remains unknown. Here, we found that bacterial indole-3-propionic acid (IPA) downregulates interleukin-1beta (IL-1β) production in M1 macrophages through inhibition of nuclear factor-kappa B (NF-κB) signaling.

The aromatic aldehyde synthase (AAS), PonAAS2, from the gall-inducing sawfly has been identified as a biosynthetic enzyme for indole-3-acetic acid (IAA), a key molecule of the plant hormone auxin, which is thought to play a role in gall induction. Unlike other insect AASs that convert Dopa, PonAAS2 uniquely converts L-tryptophan (Trp) into indole-3-acetaldehyde, a precursor of IAA. In this study, an examination of AAS enzymes from various insect species revealed that the ability to convert Trp has been acquired in only a very limited taxonomic group.

This investigation represents a pioneering effort to examine the therapeutic effects of PCB specifically in the context of CFA-induced mice, as well as to elucidate the underlying mechanisms that facilitate such effects. Our study utilized advanced methodologies, namely high-performance liquid chromatography coupled with mass spectrometry (HPLC-MS)-based metabolomics, alongside comprehensive multivariate data analysis, to identify a distinctive metabolic profile associated with acute inflammation. Through our analyses, we discovered that several potential metabolites were significantly implicated in a variety of critical metabolic pathways.

Background: To decipher the mechanisms underlying the protective role of the Mediterranean diet (MED) in Crohn's disease (CD), we explored the implications of adherence to MED on CD course, inflammatory markers, microbial and metabolite composition.
Methods: Patients with newly diagnosed CD were recruited and followed prospectively. MED adherence was assessed by repeated food frequency questionnaires (FFQ), using a predefined IBDMED score, alongside validated MED adherence screeners.
