This guiding principle led us to explore engineering Siglec-15 (S15) targeted bispecific antibody (bsAb) to enhance therapy against triple negative breast cancer (TNBC). S15 appears to be exclusively expressed on macrophages and diverse tumor cells, including human and mouse 4T1 TNBC. TGF-β is a growth hormone frequently associated with increased tumor invasiveness, including in TNBC. Here, to overcome the immune-suppressive environment within TNBC tumors to enable more effective cancer therapy, we engineered a bispecific antibody (bsAb) targeting both Siglec15 and TGF-β. In mice engrafted with orthotopic 4T1 tumors, S15/TGF-β bsAb treatment was highly effective in suppressing tumor growth, not only compared to control monoclonal antibody (mAb) but also markedly more effective than mAbs against S15 alone, against TGF-β alone, as well as a cocktail of both anti-S15 and anti-TGF-β mAbs. We did not detect liver and lung metastasis in mice treated with S15/TGF-β bsAb, unlike all other treatment groups at the end of the study. The enhanced anti-tumor response observed with S15/TGF-β bsAb correlated with a less immunosuppressive environment in the tumor. These results underscore S15-targeted bsAb as a promising therapeutic strategy for TNBC, and possibly other S15 positive solid tumors.","PeriodicalId":9263,"journal":{"name":"Bioengineering & Translational Medicine","volume":"9 5","pages":""},"PeriodicalIF":6.1,"publicationDate":"2024-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/btm2.10651","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140104967","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite advances in rehabilitation care, effective neuroprotective treatments for TBI patients are lacking. Furthermore, current drug delivery methods for TBI treatment are inefficient in targeting inflamed brain areas. To address this issue, we have developed a liposomal nanocarrier (Lipo) encapsulating dexamethasone (Dex), an agonist for the glucocorticoid receptor utilized to alleviate inflammation and swelling in various conditions. In vitro studies show that Lipo-Dex were well tolerated in human and murine neural cells. Lipo-Dex showed significant suppression of inflammatory cytokines, IL-6 and TNF-α, release after induction of neural inflammation with lipopolysaccharide. Further, the Lipo-Dex were administered to young adult male and female C57BL/6 mice immediately after controlled cortical impact injury (a TBI model). Our findings demonstrate that Lipo-Dex can selectively target the injured brain, thereby reducing lesion volume, cell death, astrogliosis, the release of pro-inflammatory cytokines, and microglial activation compared to Lipo-treated mice in a sex-dependent manner, showing a major impact only in male mice. This highlights the importance of considering sex as a crucial variable in developing and evaluating new nano-therapies for brain injury. These results suggest that Lipo-Dex administration may effectively treat acute TBI.","PeriodicalId":9263,"journal":{"name":"Bioengineering & Translational Medicine","volume":"9 4","pages":""},"PeriodicalIF":6.1,"publicationDate":"2024-02-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/btm2.10647","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139696314","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although some basic mechanisms regarding the role of myofibroblasts in the progression of muscle fibrosis have been discovered, our knowledge of the complex cell–cell, and cell–matrix interactions occurring in the fibrotic microenvironment is still rudimentary. Recently, vascular dysfunction has been emerging as a key hallmark of fibrosis through a process called endothelial-mesenchymal transition (EndoMT). Nevertheless, no effective therapeutic options are currently available for the treatment of muscle fibrosis. This lack is partially due to the absence of advanced in vitro models that can recapitulate the 3D architecture and functionality of a vascularized muscle microenvironment in a human context. These models could be employed for the identification of novel targets and for the screening of potential drugs blocking the progression of the disease. In this review, we explore the potential of 3D human muscle models in studying the role of endothelial cells and EndoMT in muscle fibrotic tissues and identify limitations and opportunities for optimizing the next generation of these microphysiological systems. Starting from the biology of muscle fibrosis and EndoMT, we highlight the synergistic links between different cell populations of the fibrotic microenvironment and how to recapitulate them through microphysiological systems.","PeriodicalId":9263,"journal":{"name":"Bioengineering & Translational Medicine","volume":"9 5","pages":""},"PeriodicalIF":6.1,"publicationDate":"2024-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/btm2.10644","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140488264","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Matrigel-based models often exhibit batch-to-batch variations, while in vivo tumor models currently produce insufficient amounts of VM. There is currently no suitable tumor model to discover new therapeutic targets against VM. Herein, we establish an extracellular matrix (ECM)-based engineered tumor model in vivo and in vitro.

Furthermore, we also investigated the role of collagen/fibronectin (FN) in melanoma progression and VM formation. Compared with cells cultured on TCPS plates, the B16F10 cells cultured on collagen/FN coated plates showed increased proliferation and stemness, and significantly enhanced invasion and formation of VM networks. Molecular mechanism analysis showed that Integrin/VE-cadherin/EphA2/PI3K/MMP-2 signaling pathways are responsible for VM formation.
