The results demonstrated that NP-NAR effectively ameliorated lipid metabolism dysbiosis, oxidative stress, insulin resistance, and inflammation in MASLD mice. Transcriptomic analysis and molecular data revealed that NP-NAR promoted fatty acid oxidation via activation of the PPAR signaling pathway, reduced hepatic lipid uptake and lipogenesis by inhibiting the expressions of key genes including CD36, ACC, and FASN.

Primary AdSCs were conditioned in serum-free medium for 72h.

Proliferation assays of primary Schwann cells after treatment with sEVs were performed. Particles meeting criteria to be classified as sEVs were detected in all fractions. However, sEVs differed by their size and phenotypic expression. A long conditioning period led to a heterogenous population of larger sEVs and increased protein per particle ratio. Moreover, the expression of tetraspanines was affected. Lastly, the proliferative effect of sEVs on Schwann cells decreased with increasing conditioning period.

In view of this, a ruthenium (Ru)-based nanobattery (termed as IRD) with cascade-charged oxygen (O<sub>2</sub>), ROS, and photodynamic-induced immunotherapy by coordination-driven self-assembly of transition-metal Ru, photosensitizer indocyanine green (ICG), and organic ligand dithiobispropionic acid (DTPA). Then, IRD is camouflaged with macrophage membranes to obtain a nanobattery (termed as IRD@M) with targeting and immune evasion capabilities. Upon intravenous administration, IRD@M with a core-shell structure, nano diameter, and good stability can specifically hoard in tumor location and internalize into tumor cells. Upon disassembly triggered by GSH, the released Ru³⁺ not only catalyzes the conversion of endogenous hydrogen peroxide (H₂O₂) into O₂ to alleviate tumor hypoxia and reduce the expression of hypoxia-inducible factor-1α (HIF-1α), but also generates hydroxyl radicals (·OH) to elevate intracellular ROS levels. This process significantly enhances the photodynamic therapy (PDT) efficacy of the released ICG. Meanwhile, the released DTPA can significantly downregulate overexpressed GSH to reduce the elimination of ROS deriving from PDT by the exchange reaction of thiol-disulfide bond. It is also found that alleviating the hypoxic tumor microenvironment synergistically enhances the PDT efficacy, which in turn cascades to recharge the subsequent immune response, significantly improving the immunosuppressive tumor microenvironment and activating systemic tumor-specific immunity. Notably, in vitro and in vivo experimental results jointly confirm that such cascade-recharged macrophage-biomimetic Ru-based nanobattery IRD@M can achieve an obvious tumor elimination while results in a minimized side effect.

It comprises various cell types, including immune cells, tumor cells, and stromal cells. Among these, cancer-associated fibroblasts (CAFs) represent a heterogeneous population with diverse origins, phenotypes, and functions. Activated CAFs secrete multiple factors that promote tumor growth, migration, angiogenesis, and contribute to chemoresistance. Additionally, CAFs secrete extracellular matrix (ECM) components, such as collagen, which form a physical barrier that hinders the penetration of chemotherapeutic and immunotherapeutic agents. This ECM also influences immune cell infiltration, impeding their ability to effectively target tumor cells. As a result, modulating the activity of CAFs has emerged as a promising strategy to enhance the efficacy of tumor immunotherapy. Nano-delivery systems, constructed from various nanomaterials with high targeting specificity and biocompatibility, offer a compelling approach to deliver therapeutic agents or immunomodulatory factors directly to CAFs. This modulation can alter CAF function, reduce their tumor-promoting effects, and thereby improve the outcomes of immunotherapy. This review provides an in-depth exploration of the origins, functions, and interactions of CAFs within the TME, particularly in the context of immune suppression.
