As such, alternatives to standard antibiotic therapies have been highly sought after to address difficult-to-treat biofilm-associated infections. A biomaterial-based approach using the innate functions of mucins is hypothesized to modulate bacterial surface attachment and virulence can provide a new therapeutic strategy against biofilms. Based on the testing in <i>Pseudomonas aeruginosa</i> biofilms, it is found that synthetic mucus biomaterials can inhibit biofilm formation and significantly reduce the thickness of mature biofilms. In addition, if synthetic mucus biomaterials can work synergistically with DNase and/or α-amylase for enhanced biofilm dispersal is evaluated. Combination treatment with these antibiofilm agents and synthetic mucus biomaterials resulted in up to 2 log reductions in the viability of mature <i>P. aeruginosa</i> biofilms.

Peripheral nerve is known to regenerate itself when the defect is small. The mechanism of nerve repair and regeneration is complex and is related to neuroimmunomodulation where there is crosstalk between Schwann cells and macrophages which respond to the injury of smaller dimensions immediately. However, regeneration of large defects requires the use of grafts. 3D bioprinting is one such promising technology with which bioengineered nerve conduits can be reproduced for the repair of injured peripheral nerves. This review outlines the mechanism of repair and regeneration of peripheral nerves and provides a detailed description of the latest developments in the fabrication of bioengineered nerve conduits. Further, various bioprinting techniques and bioinks that have been established in vitro for the fabrication of nerve conduits are discussed. In addition, this article aims to look at the in vivo applications of the bioprinted nerve conduits with respect to different types of peripheral nerve models. The challenges and future perspectives involved in fabricating bioprinted functional nerve conduits have also been discussed.</p>","PeriodicalId":7284,"journal":{"name":"Advanced Therapeutics","volume":"8 5","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adtp.202400506","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143944395","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Puerarin (Pue), an isoflavone compound, exerts protective effects on ovarian, however, with undefined mechanisms in POF. POF models were established by cyclophosphamide, and Pue and silent information regulator sirtuin 1 (SIRT1) inhibitor Selisistat (EX527) were used. Next, extracted primary rat ovarian granulosa cells (GCs) were treated with EX527 and autophagy activator rapamycin (RA). The data showed that in POF rats, Pue ameliorated estrous cycle, pathological damage, and senescence with higher ovarian index, anti-Müllerianhormone, estradiol, glutathione peroxidase, superoxide dismutase, mitochondrial DNA, and lower luteinizing hormone and follicle-stimulating hormone levels. In GCs, Pue increased cell viability, mitochondrial membrane potential, adenosine triphosphate levels, with decreased senescence and reactive oxygen species. Moreover, Pue induced mitophagy, enhanced peroxisome proliferators-activated receptor-γ coactivator-1alpha (PGC-1α), and reduced malondialdehyde, p16INK4a, p-adenosine 5′-monophosphate (AMP)-activated protein kinase (AMPK)/AMPK, mitochondrial transcription factor A, nuclear respiratory factor 1, dynamin-related protein 1, and mitochondrial fission 1 expression. Notably, the EX527 addition offset the above effects, while RA further reversed effects of EX527.
