Abstract
Serum Amyloid A (SAA) proteins are critical mediators of immune activation and metabolic regulation, bridging the acute-phase response with long-term disease dynamics. Once considered mere biomarkers of inflammation, emerging research has revealed their central role in orchestrating immune responses, lipid metabolism, and tissue remodeling. SAA proteins display context-dependent functions: they promote immune defense and tissue regeneration in some conditions, while exacerbating chronic inflammation and disease progression in others. Recent studies highlight the intricate interplay between SAA isoforms, pattern recognition receptors, and metabolic pathways, with implications for autoimmune diseases, metabolic disorders, and inflammatory pathologies. Despite their well-documented role in acute inflammation, the therapeutic potential of SAA proteins remains underexplored. Ongoing research aims to dissect their multifaceted functions and isoform-specific effects, paving the way for novel diagnostic and therapeutic strategies in immune-mediated diseases.

Mo S, Fang X, Xiao W, Huang B, Li C, Yang H, Wu Y, Wang Y, Ma H. Multi-Omics Unveils Inflammatory Regulation of Fermented Sini Decoction Dregs in Broilers Infected with Avian Pathogenic Escherichia coli. Vet Sci 2025; 12:479. [PMID: 40431572 PMCID: PMC12116022 DOI: 10.3390/vetsci12050479] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2025] [Revised: 04/28/2025] [Accepted: 05/13/2025] [Indexed: 05/29/2025] Open
Abstract
Avian colibacillosis causes significant economic losses and raises concerns for human health due to food safety risks, a problem exacerbated by the increase in antibiotic resistance. This study aimed to develop novel antibacterial strategies using fermented liquid of Sini decoction dregs to address these challenges. We analyzed the transcriptome of the chicken thymus sample GSE69014 in the GEO database to identify immune-related genes, performed molecular docking to assess compound interactions, and experimental validation via Western blot and ELISA to evaluate anti-inflammatory effects. Results revealed 11 core genes, including TLR4, critical for immune responses against the infection, with TLR4 activating key inflammatory pathways. Fermented liquid with probiotics enhanced bioactivity, and natural compounds Dioscin and Celastrol from the fermented liquid inhibited inflammation by targeting the TLR4-MD2 complex. In animal models, fermented liquid outperformed individual compounds, likely due to synergistic effects, significantly reducing inflammatory markers. These findings demonstrate that fermented liquid of Sini decoction dregs offers a promising, sustainable approach to control avian colibacillosis, mitigate antibiotic resistance, and improve poultry health, providing a scientific foundation for its application in farming to reduce economic losses and enhance food safety.
