Recently, immunotherapy, particularly immune checkpoint inhibitors (ICIs), has emerged as a crucial treatment strategy for lung cancer patients, following surgical intervention, radiotherapy, chemotherapy, and targeted drug therapies. However, the therapeutic limitations are caused owing to their low response rate and undesirable side effects such as immune-related pneumonitis. Therefore, developing new strategies to improve the efficacy of ICIs while minimizing immune-related adverse events will be crucial for cancer immunotherapy. The tumor immune microenvironment plays a significant role in the success of lung cancer immunotherapy, and the immunosuppressive characteristics of the immune microenvironment are one of the major obstacles to the poor immunotherapeutic effect. Phytochemicals, naturally occurring compounds in plants, have shown promise in enhancing cancer immunotherapy by remodeling the immunosuppressive microenvironment, offering the potential to increase the efficacy of ICIs. Therefore, this review summarizes the associated mechanisms of phytochemicals remodeling the immunosuppressive microenvironment in lung cancer. Additionally, the review will focus on the synergistic effects of combining phytochemicals with ICIs, aiming to improve anticancer efficacy and reduce side effects, which may hopefully offer novel strategies to overcome current limitations in immunotherapy.</p>","PeriodicalId":20110,"journal":{"name":"Phytotherapy Research","volume":" ","pages":""},"PeriodicalIF":6.1,"publicationDate":"2025-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143693021","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigates whether dietary fiber supplementation can prevent cardiovascular damage and high blood pressure in a genetic model of neurogenic hypertension. Six-week-old male spontaneously hypertensive rats (SHR) and their respective normotensive control, Wistar Kyoto rats (WKY), were divided into four groups: Untreated WKY, untreated SHR, SHR treated with resistant starch (SHR + RS), and SHR treated with inulin-type fructans (SHR + ITF) for 12 weeks. Additionally, a faecal microbiota transplantation (FMT) experiment was conducted, transferring faecal content from treated SHR donors to recipient SHRs. A diet rich in RS fiber reduced vascular oxidative stress, inflammation, and high blood pressure. These protective effects were associated with a reshaped gut microbiota, leading to increased short-chain fatty acid production, reduced endotoxemia, decreased sympathetic activity, and a restored balance between Th17 and Treg lymphocytes in mesenteric lymph nodes and aorta. Elevated plasma levels of acetate and butyrate in the SHR + RS group correlated with increased expression of aortic GPR41, GRP43 and PPARδ. Conversely, ITF treatment failed to prevent hypertension or endothelial dysfunction in SHR. FMT from the SHR + RS group to recipient SHR partially replicated these beneficial effects. This study highlights the antihypertensive benefits of dietary insoluble RS fiber, which are attributed to enhanced short-chain fatty acids production in the gut. This leads to improved gut permeability, reduced sympathetic tone, and diminished vascular T-cell accumulation. Therefore, dietary interventions with RS fiber may offer promising therapeutic strategies for preventing hypertension.</p>","PeriodicalId":20110,"journal":{"name":"Phytotherapy Research","volume":" ","pages":""},"PeriodicalIF":6.1,"publicationDate":"2025-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143693012","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The UC mice were treated with FA (15, 30, and 60 mg/kg) for 10 days. FA showed relatively high concentration retention in the colon within 4 h. The treatment of FA improved body weight loss, diarrhea, rectal bleeding, colon shortening, and histological damage in UC mice. It also increased the expression of the tight junction protein and decreased inflammatory cytokines in the colon. The microbiota analysis using 16S rRNA sequencing revealed that FA could alleviate gut dysbiosis in colitis mice.
