The current research on tumor fibrosis mainly focuses on cancer associated fibroblasts, which may play a dual role in promoting and inhibiting tumors. However, whether tumor cells themselves can undergo fibrosis transformation and inhibit parenchymal cells like pulmonary fibrosis to achieve the goal of inhibiting malignant progression of tumors has received less attention. On August 29, 2024, Advanced Science reported that researchers used mesoporous silica nanoparticles (MSN) loaded with trehalose mycorrhizal ester (TDM) to induce tumor cell fibrosis through the dual effects of TDM induced inflammatory granulomas and MSN induced foreign body granulomas. In this work, researchers prepared novel nanoparticles loaded with MSN and TDM, and utilized the dual induction of fibrosis by MSN and TDM to construct a mouse subcutaneous loaded tumor model. They observed its anti-tumor effect and the possibility of inhibiting tumor malignant progression by inducing tumor cell fibroblast transformation, in order to develop a new anti-tumor strategy. Combining in vitro and in vivo studies, it has been shown that TDM/MSN (TM) can effectively enter solid tumors and induce tumor fibrosis, manifested by collagen internalization and inhibition of proliferation and invasion ability, suggesting a potential role in the treatment of tumor fibrosis. But further research has found that extracellular DNA (ecDNA) mediates resistance to fibrosis induction. In order to comprehensively improve the therapeutic effect, WRN nuclease binds with TM to form a novel nanoparticle (TMW), which can effectively clear ecDNA and promote fibroblast like transformation of tumor cells. Its inhibitory effect on cancer progression has been verified in the PDX model. This study reveals the potential of TDM/MSN-WRN (TMW) to induce fibroblast like transformation and related intracellular collagen deposition in tumor cells, thereby inhibiting malignant progression of tumors. It provides a new paradigm for anti-tumor therapy and offers a new theoretical basis and strategy for designing anti-tumor drugs.

Read MoreThe clearance kinetics of functional inorganic nanoparticles are generally slow, which may pose potential biosafety issues for in vivo applications. One possible elimination pathway for inorganic nanoparticles is renal clearance, but the effectiveness of renal clearance largely depends on the surface physicochemical properties of the given particles, rather than their size and shape. On May 13, 2024, the Journal of Nanobiotechnology reported that researchers had designed and successfully utilized three small molecule ligands with bisphosphonate groups but different end groups (i.e. anionic, cationic, and zwitterionic groups) to encapsulate ultra small Fe3O4 nanoparticles, and studied the renal clearance behavior of surface ligand regulated ultra small nanoparticles. Systematic studies have shown that the ultra small Fe3O4 nanoparticles modified with these surface ligands not only have sufficiently small hydrodynamic dimensions to be cleared by the kidneys, but also exhibit excellent T1/T2 MRI contrast enhancement performance. Combining bladder MRI and urinary Fe content measured by ICP-OES, researchers found Fe3O4 nanoparticles coated with zwitterionic ligands（ Fe3O4@DMSA ）It exhibits excellent renal clearance due to reduced absorption by RES. By utilizing the diphosphate anchoring group of hydrophilic ligands, Fe3O4@DMSA Successfully labeled with 99mTc to achieve efficient renal clearance MRI/SPECT dual-mode imaging nanoprobes. It is worth noting that this nanoprobe has demonstrated satisfactory imaging capabilities in the 4T1 xenograft tumor mouse model. In addition, researchers also conducted safety assessment experiments to evaluate Fe3O4@DMSA The biocompatibility was evaluated in vitro and in vivo. This study provides a simple and effective strategy for constructing kidney removable nanoparticles that can be used for precise disease diagnosis.

Read MoreOsteoarthritis (OA) is a common disease characterized by subchondral fractures in its early stages, and there is currently no precise and specific treatment method available. On June 14, 2024, Advanced Materials reported that researchers synthesized a novel multifunctional scaffold using photopolymerized modified hyaluronic acid (GMHA) as a matrix in the presence of hydroxyapatite based hollow porous magnetic microspheres (HAp-Fe3O4), which is expected to solve this problem. The results of subchondral bone repair indicate that the carefully designed scaffold has the most suitable properties for subchondral bone repair. The porous structure of the magnetic microspheres inside the scaffold promotes the effective transfer of exogenous vascular endothelial growth factor (VEGF) loaded, and the Fe3O4 nanoparticles assembled in the microspheres promote osteogenic differentiation of bone marrow mesenchymal stem cells and accelerate new bone formation. These characteristics enable the scaffold to exhibit good subchondral bone repair properties and achieve high cartilage repair scores. The treatment results have shown that subchondral bone support significantly affects the process of upper cartilage repair. In addition, magnetic resonance imaging monitoring shows that Fe3O4 nanoparticles are gradually replaced by new bone during subchondral defect repair, allowing for non-invasive and radiation free evaluation to track the development of new bone during OA repair. This hydrogel scaffold achieves long-term in vivo tracking of subchondral bone and cartilage through its magnetic imaging effect, which meets the clinical needs. After further research and improvement, it is expected to be used for clinical applications.

Read MoreAccurate imaging of collateral circulation and ischemic penumbra is crucial for the diagnosis and treatment of acute ischemic stroke (AIS). Unfortunately, there is currently a lack of high-sensitivity and high-resolution in vivo imaging technology to meet this requirement. On July 4, 2024, Small reported that researchers had developed for the first time a contrast-enhanced magnetic sensitive weighted imaging (CE-SWI) technique, which is expected to meet the high-precision imaging needs. This technology utilizes Fe3O4 nanoparticles modified with dextran（ Fe3O4@Dextran NPs can perform high sensitivity and resolution imaging of AIS at 9.4T. Researchers synthesized it at room temperature using a simple co precipitation method Fe3O4@Dextran Nanoparticles have the advantages of small size (hydrodynamic size of 25.8nm), good solubility, high transverse relaxation (r2) (r2 reaches 51.3mM-1s-1 at 9.4T), and good biocompatibility. Fe3O4@Dextran Nano particle enhanced SWI can easily highlight cerebral blood vessels under a 9.4TMR scanner, with significantly improved contrast and a resolution of 0.1 millimeters, enabling clear identification of collateral circulation spaces in a rat model of middle cerebral artery occlusion (MCAO). In addition, Fe3O4@Dextran The SWI enhanced by NPs, through matching analysis with other multimodal magnetic resonance sequences, helps to accurately depict the ischemic core, collateral branches, and ischemic penumbra after AIS. The study's Fe3O4@Dextran Nanoparticle enhanced SWI provides a highly sensitive and high-resolution imaging tool for personalized feature description and precise treatment of stroke patients.
