Escin, derived from Aesculus hippocastanum, has several pharmacological functions, including anti-inflammatory and anti-viral effects, and exhibits glucocorticoid-like actions in inflammatory responses. However, its impact on AD has not been extensively studied. We investigated the anti-inflammatory effects of escin on AD and elucidate its underlying mechanism of actions in the dermatophagoides farinae extract (DFE)-induced AD mouse model. The AD-induced group treated with escin showed a significant reduction in immunoglobulin E (IgE) levels, ear thickness, epidermal thickness, and mast cell infiltration compared to the AD group. Additionally, escin significantly reduced the dermatitis score and the sizes of the spleen and lymph nodes. Notably, escin inhibited the reduction of filaggrin expression induced by DFE, while suppressing the upregulation of thymic stromal lymphopoietin (TSLP), interleukin (IL)-4, IL-13, IL-1β, and tumor necrosis factor (TNF)-α. Escin also significantly suppressed DFE-induced NF-κB expression. Interestingly, pre-treatment with RU486, a glucocorticoid receptor (GR) antagonist, attenuated the therapeutic effects of escin. In line with these findings, escin modulated the IFN-γ/TNF-α-mediated changes in TSLP and filaggrin expression in HaCaT keratinocyte cells. Furthermore, escin inhibited the lipopolysaccharide (LPS)-induced overproduction of nitric oxide (NO), protein expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2), and mRNA expression of IL-6 and IL-1β in RAW 264.7 cells. These results indicate that escin may offer therapeutic potential in treating AD through the GR.","PeriodicalId":16481,"journal":{"name":"Journal of microbiology and biotechnology","volume":"35 ","pages":"e2410025"},"PeriodicalIF":2.5,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11930568/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143624981","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

HP7 administration significantly enhanced peristalsis by upregulating the expression of smooth muscle contraction-related genes, such as the 5HT4 receptor, anoctamin-1, ryanodine receptor 3, and smooth muscle myosin light-chain kinase. In addition, digestive factors, including GI regulatory hormones such as gastrin, gastric inhibitory peptide, and peptide YY, and the activity of digestive enzymes, such as amylase, trypsin, and lipase, were restored to normal levels.

We compared fecal microbiome and urine metabolome profiles in type 2 diabetes patients versus healthy controls to evaluate their respective diagnostic potential. Using a cohort of 94 subjects (48 diabetics, 46 controls), this study employed 16S rRNA amplicon sequencing for fecal microbiome analysis and GC-MS for urinary metabolomics. While fecal microbiome alpha diversity showed no significant differences between groups, urinary metabolomics demonstrated distinct structural patterns and higher evenness in type 2 diabetes patients. The study identified several diabetes-associated urinary metabolites, including elevated levels of glucose and inositol, along with decreased levels of 6 urine metabolites including glycolic acid, hippurate, and 2-aminoethanol. In the fecal microbiome, genera such as Escherichia-Shigella showed positive correlation with type 2 diabetes, while Lacticaseibacillus demonstrated negative correlation. Receiver operating characteristic curve analyses revealed that urinary metabolites exhibited superior diagnostic potential compared to fecal microbiome features, with an area under the curve of 0.90 for the combined metabolite model versus 0.82 for the integrated bacterial taxa model. These findings suggest that urinary metabolomics may offer a more reliable approach for type 2 diabetes diagnosis compared to fecal 16S metabarcoding, while highlighting the potential of multi-marker panels for enhanced diagnostic accuracy.","PeriodicalId":16481,"journal":{"name":"Journal of microbiology and biotechnology","volume":"35 ","pages":"e2411071"},"PeriodicalIF":2.5,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143730351","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Serotyping is extensively applied in the classification of L. monocytogenes and is crucial in the early stage of epidemiological tracing. Among the 13 serovars, 1/2a, 1/2b, 1/2c, and 4b are the ones most frequently isolated. Numerous PCR-based methods have been presented, however, their target genes, lmo0737, ORF2110 and ORF2819, are prone to horizontal transfer or loss in certain strains, thus leading to incorrect serovar designation. Herein, we selected novel sero-specific genes and developed an improved multiplex PCR assay. The specificity of our assay was confirmed by the use of target and nontarget Listeria reference strains, as well as by the use of isolates yielding incorrect profiles in previous studies. Sensitivity tests indicated that a minimum of 5 ng of genomic DNA or approximately 3 × 106 CFU of pure culture could be detected. Many collected isolates and genomes of global isolates were used to evaluate the specificity and reproducibility of our assay. The agreement between our assay and the agglutination test was 95%, and the one between our assay and the Doumith scheme was 97%. However, our assay overcomes the drawbacks of currently used PCR-based approaches by exhibiting 100% accuracy for certain strains and clones, for instance, ST782 within the hypervirulent CC2 and ST218 that were incorrectly assigned by the Doumith scheme. In conclusion, the developed assay herein will be a powerful tool and an alternative for the classification of L. monocytogenes strains in foodborne outbreak investigations and surveillance programs.","PeriodicalId":16481,"journal":{"name":"Journal of microbiology and biotechnology","volume":"35 ","pages":"e2411081"},"PeriodicalIF":2.5,"publicationDate":"2025-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11925748/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143624769","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to establish a mouse model of lung injury induced by lipopolysaccharides (LPS) derived from Klebsiella pneumoniae and to evaluate whether Cordyceps militaris ARA301 extract (CME) can prevent lung injury. CME was orally administered to mice for three consecutive days, followed by intranasal LPS administration. Mice were sacrificed 24 h later to analyze immune cell alterations and inflammatory responses through bronchoalveolar lavage fluid (BALF) and tissue analyses. CME administration inhibited immune cell infiltration, tissue fibrosis, and excessive mucus deposition induced by intranasal LPS administration. Furthermore, CME suppressed the expression of mucin 5AC (MUC5AC), a protein involved in mucus production, as well as the expression of inducible nitric oxide synthase (iNOS), and cyclooxygenase-2 (COX-2) in lung tissues. In BALF, CME reduced the production of interleukin-1 beta (IL-1β), interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-α), and C-X-C motif chemokine ligand 1 (CXCL1), which were elevated due to LPS administration. Additionally, CME decreased the total immune cell, neutrophil, monocyte, and eosinophil numbers in BALF. The anti-inflammatory activity of CME was evaluated in vitro using RAW 264.7 cells. CME treatment reduced the secretion of pro-inflammatory cytokines induced by LPS and inhibited the phosphorylation of p65, inhibitor of kappa B alpha (IκBα), and IκB kinase alpha (IKKα).
