After homogenizing at 35 Hz for 4 min, the sample was sonicated in an ice-water bath for 5 min, and this homogenization-sonication cycle was repeated twice. The sample was allowed to stand at -40 °C for 1 h, then centrifuged at 12000 rpm and 4 °C for 15 min. A 400 μL aliquot of the supernatant was evaporated to dryness under nitrogen, reconstituted with 100 μL of water containing 0.1% formic acid, and centrifuged again at 12000 rpm and 4 °C for 15 min. The clear supernatant was used for UHPLC-MS/MS analysis. All pretreatment steps were performed on ice to avoid metabolite degradation. The control samples set in the experiment included: Quality Control (QC) samples, prepared by mixing equal volumes of supernatants from all experimental samples; solvent blank controls, containing only extraction solution without samples, used to eliminate interference from reagent contamination.&lt;/p></extraction_protocol><organism>Pekin (Duck (domestic))</organism><full_dataset_link>https://www.ebi.ac.uk/metabolights/MTBLS13667</full_dataset_link><author>LIhong Zhao.

Specifically, dietary ferulic acid enriches&amp;nbsp;Peptostreptococcus anaerobius&amp;nbsp;, enhancing microbial conversion of tryptophan&amp;nbsp;to 3-indoleacrylic acid&amp;nbsp;both in vivo&amp;nbsp;and in vitro.&amp;nbsp;Mechanistically,&amp;nbsp;by combining single-cell RNA sequencing and surface plasmon resonance, we demonstrate that 3-indoleacrylic acid functionally antagonizes Aflatoxin B1-induced hyperactivation&amp;nbsp;of the AhR pathway, thereby suppressing AhR-driven ferroptosis. This functional mechanism was validated through genetic knockdown and pharmacological interventions. Crucially,&amp;nbsp;we reveal that 3-indoleacrylic acid&amp;nbsp;ameliorates Aflatoxin B1-induced liver inflammation by reprogramming the subset composition and function of macrophages, which was confirmed by macrophage-depletion models.&amp;nbsp;Collectively, our findings unveil a precise molecular mechanism of host-microbe crosstalk, identifying the Peptostreptococcus anaerobius-derived tryptophan metabolite 3-indoleacrylic acid&amp;nbsp;as a critical signaling mediator that inhibits Aflatoxin B1-induced hepatic AhR hyperactivation, ferroptosis, and macrophage reprogramming. This study not only proposes a viable dietary strategy to combat global aflatoxicosis but also provides insights into how specific microbial metabolites can be harnessed to therapeutically modulate hepatic injury and&amp;nbsp;immune homeostasis.&lt;/p></description><dates><publication>2026-08-13</publication><submission>2026-01-13</submission></dates><accession>MTBLS13667</accession><cross_references><HMDB>HMDB0001476</HMDB><HMDB>HMDB0000732</HMDB><HMDB>HMDB0000763</HMDB><HMDB>HMDB0000259</HMDB><HMDB>HMDB0001855</HMDB><HMDB>HMDB0000472</HMDB><HMDB>HMDB0004096</HMDB><HMDB>HMDB0001123</HMDB><HMDB>HMDB0000734</HMDB><HMDB>HMDB0000197</HMDB><HMDB>HMDB0029739</HMDB><HMDB>HMDB0029737</HMDB><HMDB>HMDB0003447</HMDB><HMDB>HMDB0000671</HMDB><HMDB>HMDB0061755</HMDB><HMDB>HMDB0000738</HMDB><HMDB>HMDB0002302</HMDB><HMDB>HMDB0000682</HMDB><HMDB>HMDB0000684</HMDB><HMDB>HMDB0000715</HMDB><HMDB>HMDB0001389</HMDB><HMDB>HMDB0001488</HMDB><HMDB>HMDB0001238</HMDB><HMDB>HMDB0000466</HMDB><HMDB>HMDB0000929</HMDB><HMDB>HMDB0000303</HMDB><HMDB>HMDB0000881</HMDB><HMDB>HMDB0006524</HMDB><HMDB>HMDB0038666</HMDB></cross_references></HashMap>
