Artemisinin-based combination therapies (ACTs) are the current standard treatment, resistance development necessitates the exploration of new therapeutic targets. Recent evidence suggests that targeting oxidative stress to arrest blood stage ring to schizont growth progression in <i>Plasmodium</i> could offer a novel approach to combat drug-resistant malaria. Phytomolecules have been recognized for their potential to modulate oxidative stress with artemisinin derivatives. In the present study, we aimed to evaluate the effectiveness of formononetin (FMT), a natural isoflavonoid, alone and in combination with artesunate (ART) against multidrug-resistant <i>P. falciparum</i> (K1) strain and to decipher the underlying mechanism of action. The study presents compelling evidence demonstrating the anti-plasmodial action of FMT alone (IC<sub>50</sub> value 212µM) and synergistic interaction (FICI 0.13) with ART at a 1:1 ratio against the K1 strain of <i>P. falciparum</i>. The combination treatment affected the progression of <i>P. falciparum</i> from the ring stage to the schizont and showed the effect at asexual erythrocytic stages. Moreover, the combination resulted in a notable increase in reactive oxygen species (ROS) levels, both independently and in combination with ART. In combination with ART, FMT effectively modulated the total glutathione (GSH) level. Moreover, FMT and ART demonstrated the ability to induce apoptosis-like death of parasites, as evidenced by the Lipid peroxidation (malondialdehyde-MDA) and DNA fragmentation (TUNEL) levels. These results indicate that FMT could potentially ameliorate the growth of multidrug-resistant malaria parasites, enhance the effects of ART, and be suitable for developing anti-plasmodial agents from a cheap and sustainable source.</p></div>","PeriodicalId":8279,"journal":{"name":"Archives of Microbiology","volume":"207 6","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143856641","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The distribution of ARGs varies according to the type of resistance genes, seasonal changes, and the medium in which they are present. ARGs are disseminated into the surrounding environment via pathways such as manure application, wastewater discharge, and aerosol diffusion. They may be absorbed by humans, accumulating in the intestinal microbiota and subsequently affecting human health. The spread of ARGs is influenced by the interplay of microbial communities, antibiotics, heavy metals, emerging pollutants, and environmental factors.

Probiotic-derived EVs can serve as nanocarriers for therapeutic cargo, particularly in enzyme replacement therapy (ERT). Traditional ERT for lysosomal storage diseases (LSDs) faces significant challenges, including the inability of enzymes to cross the blood–brain barrier (BBB) and their susceptibility to degradation. Studies show EVs can transport enzyme cargoes across the BBB, accurately delivering them to tissues affected by LSDs. Probiotic EVs also possess immunomodulatory properties, providing therapeutic benefits in inflammatory conditions. However, their potential for delivering deficient enzymes in LSDs remains unclear. This review discusses using probiotic EVs in ERT for targeted enzyme delivery to treat LSDs more efficiently than other exosomes. This novel strategy minimizes off-target delivery and enhances immunomodulatory effects, making it more advantageous than live probiotic bacteria. Probiotic EVs show promise for therapeutic approaches, especially in treating LSDs and inflammatory diseases, by modulating immune responses and delivering enzymes across biological barriers like the BBB. Future research should optimize production, engineer targeted therapies, and confirm safety and efficacy through clinical trials.
