A key hurdle is melittin (Mel), bee venom's main anti-inflammatory component, which degrades rapidly when orally ingested, leading to decreased efficacy and increased toxicity. This study proposes a solution by encapsulating melittin in liposomes to enhance stability and lessen side effects, expanding its clinical applicability. Additionally, the advancement of microneedle technology, which bypasses gastrointestinal issues by targeting the stratum corneum, opens a novel pathway for RA treatment. Employing soluble microneedles loaded with melittin-encapsulated liposomes (Mel-Lip) enables effective transdermal delivery. Results from an adjuvant-induced RA animal model show that Mel-Lip microneedles improve foot health, repair cartilage, and lower inflammatory markers, highlighting microneedling with transdermal nanocarriers as a promising, patient-friendly approach for RA management.</div></div>","PeriodicalId":19050,"journal":{"name":"Nanomedicine : nanotechnology, biology, and medicine","volume":"64 ","pages":"Article 102806"},"PeriodicalIF":4.2,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143040415","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 tear fluid from diabetes mellitus patients has a higher concentration of glucose, which accelerates the breakdown of lysozyme and, as a result, the quick loss of the dendritic structure.
