Numerous studies have focused on developing innovative therapies, as conventional treatments are hampered by high toxicity, drug resistance, and relapse. In recent decades, anti-leishmanial immunotherapy — aimed at triggering or modulating the host's immune response — has gained momentum, with various immunomodulators being tested in experimental and clinical settings. However, achieving effective immunotherapy remains challenging, as it requires a delicate balance between enhancing protective, parasite-specific immune responses and avoiding harmful hyperinflammation. In this context, we evaluated quercetin, a natural flavonoid with reported immunomodulatory properties, alone and in combination with Amphotericin B (AmB), against <em>Leishmania infantum</em> promastigotes and during human monocyte infection. Infected and non-infected PBMCs were assessed for parasite viability and cytotoxicity; monocyte infection rates, reactive oxygen species (ROS), nitric oxide (NO) production, and cytokine profiles. Quercetin showed significant anti-promastigote activity and, in combination with AmB, enhanced parasite death, indicating synergistic effects. It also reduced monocyte infection rates, enhanced ROS production, and downregulated levels of IL-6, IL-10, and IL-17, without altering NO production. These findings support the concept of quercetin as a dual-action agent, exerting direct anti-leishmanial effects while fine-tuning the host immune response. By promoting beneficial immunological pathways and dampening potentially deleterious cytokines, quercetin exemplifies the “trapeze act” of immunotherapy, suggesting its potential as an adjuvant to conventional chemotherapy in visceral leishmaniasis.</div></div>","PeriodicalId":297,"journal":{"name":"Cytokine","volume":"196 ","pages":"Article 157047"},"PeriodicalIF":3.7,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145256892","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This complex condition involves nutritional deficiencies, gut dysfunction, hormonal imbalances, and a critical disruption in muscle protein metabolism. However, chronic inflammation in the heart failure is the key driver, triggering the release of cytokines like TNF-α, IL-6, IL-1, IL-10 and TGF-β. These cytokines significantly impact muscle metabolism, promoting protein breakdown while hindering protein synthesis. Elevated TNF-α levels induce anorexia, worsening weight loss, and muscle depletion. IL-6 acts as a potent muscle-wasting agent, upregulating protein degradation via the ubiquitin-proteasome system. Similarly, IL-1 activates pathways that promote protein breakdown and suppress cell proliferation. TGF-β, despite its diverse functions, contributes to muscle atrophy by increasing protein degradation. In contrast, the anti-inflammatory cytokine IL-10 promotes protein synthesis by suppressing pathways that normally inhibit it. Understanding these cytokine actions provides valuable insights into cardiac cachexia and paves the way for targeted therapies aimed at modulating these pathways to prevent or reverse muscle wasting in heart failure.

In HGECs, lipopolysaccharide (LPS) treatment induced abnormal cell viability and heightened inflammatory responses, both of which were attenuated by the PPARγ agonist pioglitazone. Pioglitazone selectively promoted apoptosis in LPS-treated cells. At the molecular level, LPS increased expression of TLR2, TLR4, and TLR5, leading to NF-κB pathway activation; PPARγ activation suppressed both TLR expression and NF-κB signaling, coinciding with reduced cytokine release.</div></div><div><h3>Conclusions</h3><div>The current study demonstrates that PPARγ activation exerts anti–<em>H. pylori</em> effects during gastric ulcer progression by inhibiting the TLR/NF-κB signaling pathway.</div></div>","PeriodicalId":297,"journal":{"name":"Cytokine","volume":"196 ","pages":"Article 157061"},"PeriodicalIF":3.7,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145353162","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
