Clostridioides difficile (C. difficile) toxin B (TcdB) is essential for C. difficile pathogenicity. TcdB induces apoptosis in host cells by internalizing and utilizing its glycosyltransferase activity to modify members of the small GTPase protein family through glycosylation. The intestinal environment is critical for the colonization of C. difficile, and the use of broad-spectrum antibiotics disrupts the balance of the gut microbiota, leading to increased susceptibility of the host to C. difficile. At present, the mainstream clinical approach for treating C. difficile infection (CDI) involves antibiotic therapies such as vancomycin, which disrupt the gut microbiota and are associated with a considerable risk of infection recurrence. Therefore, there is an urgent clinical need to develop new strategies to combat CDI. Here, we have identified a natural compound, equol, which inhibits the TcdB-mediated glycosylation of Rac1 through direct interaction, thereby reducing TcdB-induced cell death. Equol functions as an inhibitor of indoleamine 2,3-dioxygenase 1 (IDO1) and tryptophan 2,3-dioxygenase (TDO), effectively suppressing the conversion of tryptophan to kynurenine in the intestinal tract while preserving the integrity of the gut microbiota. Concurrently, equol exhibits robust antioxidant properties, which markedly reduced TcdB-mediated oxidative damage and subsequent cell death. These findings suggest that equol holds therapeutic potential for the treatment of CDI. © 2025

Valine is an essential amino acid and a type of branched-chain amino acid. Due to the involvement of branchedchain amino acids in various metabolic pathways, there has been a surge of interests in valine nutrition and its role in animal physiology. In pigs, the interactions between valine and other branched-chain amino acids or aromatic amino acids are complex. In this review, we delve into the interaction mechanism, metabolic pathways, and biological functions of valine. Appropriate valine supplementation not only enhances growth and reproductive performances, but also modulates gut microbiota and immune functions. Based on past observations and interpretations, we provide recommended feed levels of valine for weaned piglets, growing pigs, gilts, lactating sows, barrows and entire males. The summarized valine nutrient requirements for pigs at different stages offer valuable insights for future research and practical applications in animal husbandry.

With gradual ban on the use of antibiotics, the deficiency and excessive use of trace elements in intestinal health is gaining attention. In mammals, trace elements are essential for the development of the immune system, specifically T-cell proliferation,and differentiation. However, there remain significant gaps in our understanding of the effects of certain trace elements on T-cell immune phenotypes and functions in pigs. In this review, we summarize the specificity, development, subpopulations, and responses to pathogens of porcine T cells and the effects of functional trace elements(e.g., iron, copper, zinc, and selenium) on intestinal T-cell immunity during early-life health in pigs. Furthermore, we discuss the current trends of research on the crosstalk mechanisms between trace elements and T-cell immunity. The present review expands our knowledge of the association between trace elements and T-cell immunity and provides an opportunity to utilize the metabolism of trace elements as a target to treat various diseases.

Background: Oxidative stress is a key factor that influences piglets' health. Taurine plays an imperative role in keeping the biological system from damage. This study was conducted to investigate the protective effect of taurine against muscle injury due to the secondary effect of diquat ***: Our study found that taurine effectively and dose-dependently alleviated the diquat toxicity induced rise of feed/gain, with a concurrent improvement of carcass lean percentage. The plasma content of taurine was considerably increased in a dose-dependent manner. Consequently, dietary taurine efficiently improved the activity of plasma antioxidant enzymes. Furthermore, taurine attenuated muscle damage by restoring mitochondrial micromorphology, suppressing protein degradation and reducing the percentage of apoptotic cells in the skeletal muscle. Taurine supplementation also suppressed the genes expression levels of the antioxidant-, mitochondrial biogenesis-, and muscle atrophy-related genes in the skeletal muscle of piglets with oxidative ***: These results showed that the dose of 0.60% taurine supplementation in the diet could attenuate skeletal muscle injury induced by diquat toxicity. It is suggested that taurine could be a potential nutritional intervention strategy to improve growth performance.
