Abstract
Trichinella spiralis is recognized for its ability to regulate host immune responses. The serine protease inhibitor of T. spiralis (Ts-SPI) participates in T. spiralis-mediated immunoregulatory effects. Studies have shown that helminth therapy exhibits therapeutic effects on metabolic diseases. In addition, we previously found that T. spiralis-derived crude antigens could alleviate diet-induced obesity. Thus, Ts-SPI was hypothesized to alleviate non-alcoholic fatty liver disease (NAFLD). Herein, recombinant Ts-SPI (rTs-SPI) was prepared from the muscle larvae T. spiralis. The relative molecular mass of rTs-SPI was approximately 35,000 Da, and western blot analysis indicated good immunoreactivity. rTs-SPI ameliorated hepatic steatosis, inflammation, and pyroptosis in NAFLD mice, which validated the hypothesis. rTs-SPI also reduced macrophage infiltration, significantly expanded Foxp3+ Treg population, and inactivated TLR4/NF-κB/NLRP3 signaling in the liver. Furthermore, rTs-SPI treatment significantly shifted the gut microbiome structure, with a remarkable increase in beneficial bacteria and reduction in harmful bacteria to improve gut barrier integrity. Finally, Abx-treated mice and FMT confirmed that gut-liver crosstalk contributed to NAFLD improvement after rTs-SPI treatment. Taken together, Taken together, these findings suggest that rTs-SPI exerts therapeutic effects in NAFLD via anti-inflammatory activity and gut-liver crosstalk.

ACS Pharmacol Transl Sci 2024; 7:432-444. [PMID: 38357280 PMCID: PMC10863434 DOI: 10.1021/acsptsci.3c00276] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2023] [Revised: 12/27/2023] [Accepted: 12/29/2023] [Indexed: 02/16/2024]
Abstract
Nonalcoholic fatty liver disease (NAFLD) is a liver disease characterized by hepatic steatosis, inflammation, and fibrosis, as well as gut dysbiosis. No approved effective therapeutic medicine is available to date for NAFLD. Helminth therapy is believed to be a novel direction and therapeutic strategy for NAFLD. Our previous study showed that Trichinella spiralis-derived antigens (TsAg) had the potential for partially alleviating obesity via regulating gut microbiota. However, the effect of TsAg on NAFLD remains unclear. In this study, high-fat diet (HFD)-induced model mice were treated with TsAg and microbiota transplantation experiments, and alterations in the pathogenesis of nonalcoholic liver disease were assessed. The results showed that TsAg markedly reduced hepatic steatosis, improved insulin resistance, and regulated the abnormal expression of hepatic lipid-related genes. Of note, TsAg ameliorated hepatic inflammation by decreasing pro-inflammatory TNF-α and IL-1β, suppressing hepatic macrophage infiltration, as well as promoting M2 macrophage polarization. Moreover, TsAg reversed gut dysbiosis, as especially indicated by an increase in beneficial bacteria (e.g., Akkermansiaceae and Rikenellaceae). Furthermore, our study found that TsAg reduced LPS hepatic translocation and hepatic TLR4/NF-κB signaling, which further contributed to inhibiting hepatic inflammation. In addition, TsAg inhibited hepatic oxidative stress involving Nrf2/NQO-1 signaling. Microbiota transplantation showed that TsAg-altered microbiota is sufficient to confer protection against NAFLD in HFD-induced mice. Overall, these findings suggest that TsAg involving gut-liver axis and Nrf2/NQO-1 signaling is a novel promising candidate for NAFLD treatment. TsAg restores intestinal microbiota and intestinal barrier to inhibit bacteria and LPS translocation into the liver, contributing to reduce inflammation, oxidative stress, and hepatic steatosis in the liver of NAFLD mice. The effects were attributed to, at least in part, the inactivation of NF-κB pathway and the activation of Nrf-2/NQO-1 pathway. This study provides new insights for understanding immune modulation by T. spiralis-derived products as well as the potential application of TsAg as a modality for NAFLD.

Front Vet Sci 2023; 10:1208538. [PMID: 37601754 PMCID: PMC10433203 DOI: 10.3389/fvets.2023.1208538] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2023] [Accepted: 07/17/2023] [Indexed: 08/22/2023] Open
Abstract
Trichinella spiralis (T. spiralis) muscle-larva excretory/secretory products (ML-ESPs) is a complex array of proteins with antitumor activity. We previously demonstrated that ML-ESPs inhibit the proliferation of A549 non-small cell lung cancer (NSCLC) cell line. However, the mechanism of ML-ESPs against A549 cells, especially on the transcriptional level, remains unknow. In this study, we systematically investigated a global profile bioinformatics analysis of transcriptional response of A549 cells treated with ML-ESPs. And then, we further explored the transcriptional regulation of genes related to glucose metabolism in A549 cells by ML-ESPs. The results showed that ML-ESPs altered the expression of 2,860 genes (1,634 upregulated and 1,226 downregulated). GO and KEGG analysis demonstrated that differentially expressed genes (DEGs) were mainly associated with pathway in cancer and metabolic process. The downregulated genes interaction network of metabolic process is mainly associated with glucose metabolism. Furthermore, the expression of phosphofructokinase muscle (PFKM), phosphofructokinase liver (PFKL), enolase 2 (ENO2), lactate dehydrogenase B (LDHB), 6-phosphogluconolactonase (6PGL), ribulose-phosphate-3-epimerase (PRE), transketolase (TKT), transaldolase 1 (TALDO1), which genes mainly regulate glycolysis and pentose phosphate pathway (PPP), were suppressed by ML-ESPs. Interestingly, tricarboxylic acid cycle (TCA)-related genes, such as pyruvate dehydrogenase phosphatase 1 (PDP1), PDP2, aconitate hydratase 1 (ACO1) and oxoglutarate dehydrogenase (OGDH) were upregulated by ML-ESPs. In summary, the transcriptome profiling of A549 cells were significantly altered by ML-ESPs. And we also provide new insight into how ML-ESPs induced a transcriptional reprogramming of glucose metabolism-related genes in A549 cells.
