IL-17A/CEBPβ/OPN/LYVE-1 axis inhibits anti-tumor immunity by promoting tumor-associated tissue-resident macrophages.

Tumor-associated macrophages (TAMs) are a critical component of the immunosuppressive tumor microenvironment, comprising monocyte-derived macrophages (MDM-TAMs) and tissue-resident macrophages (TRM-TAMs). Here, we discovered that TRM-TAMs mediate the pro-tumor effects of interleukin (IL)-17A and that IL-17A-driven tumor progression requires tumor cell production of osteopontin (OPN). Mechanistically, we identified CEBPβ as a transcription factor downstream of IL-17A in tumor cells and LYVE-1 as an OPN receptor on TRM-TAMs.

Ozone promotes macrophage efferocytosis and alleviates neuropathic pain by activating the AMPK/Gas6-MerTK/SOCS3 signaling pathway.

Background: Neuropathic pain (NPP) is a multifaceted pain syndrome that occurs as a consequence of physical injury or underlying diseases, with an incidence rate of 7%-10%, NPP poses a significant clinical challenge as current treatment options are ineffective. The accumulation of apoptotic cells and neuroinflammation play crucial roles in the pathological mechanisms of NPP. Here, we aim to investigate strategies for effectively clearing apoptotic cells and provide therapeutic interventions for NPP.

Granulocyte-like myeloid-derived suppressor cells: The culprits of neutrophil extracellular traps formation in the pre-metastatic niche.

Neutrophil extracellular traps (NETs) have been shown to exhibit chemotactic effects on circulating tumor cells at metastatic sites, promoting the progression of colorectal cancer liver metastasis (CRLM). However, the origin and factors contributing to the formation of NETs (NETosis) in the pre-metastatic niche (PMN) of target organs remain unclear. In this study, we investigated the relationship between phosphatase of regenerating liver-3 (PRL-3), myeloid-derived suppressor cells (MDSCs), neutrophils, and NETs through a retrospective clinical cohort study and a mouse model of CRLM.

Modulation of Charge Redistribution in Heterogeneous CoSe-NiSe Coupling with TiCT MXene for Hydrazine-Assisted Water Splitting.

Integrating abundant dual sites of hydrazine oxidation reaction (HzOR) and hydrogen evolution reaction (HER) into one catalyst is extremely urgent toward energy-saving H production. Herein, CoSe-NiSe heterostructure coupling with TiCT MXene (CoSe-NiSe/MXene) is fabricated on nickel foam (NF) to enhance the catalytic performance. The heterogeneous CoSe-NiSe and MXene coupling effect can change the coordination of Ni and Co, resulting in adjusted interfacial electronic field and enhanced electron transfer from NiSe to CoSe especially near MXene surface.

PTPRZ1 dephosphorylates and stabilizes RNF26 to reduce the efficacy of TKIs and PD-1 blockade in ccRCC.

Clear cell renal cell carcinoma (ccRCC), the most common subtype of renal cell carcinoma, often exhibits resistance to tyrosine kinase inhibitors (TKIs) when used as monotherapy. However, the integration of PD-1 blockade with TKIs has significantly improved patient survival, making it a leading therapeutic strategy for ccRCC. Despite these advancements, the efficacy of this combined therapy remains suboptimal, necessitating a deeper understanding of the underlying regulatory mechanisms.

SENP1 prevents high fat diet-induced non-alcoholic fatty liver diseases by regulating mitochondrial dynamics.

Mitochondrial dynamics plays a crucial role in the occurrence and development of non-alcoholic fatty liver diseases (NAFLD). SENP1, a SUMO-specific protease, catalyzes protein de-SUMOylation and involves in various physiological and pathological processes. However, the exact role of SENP1 in NAFLD remains unclear.

Functional characterization of prenyltransferases involved in de novo synthesis of isoprenoids in the leaf beetle Monolepta hieroglyphica.

Prenyltransferases play a pivotal role in the isoprenoid biosynthesis and transfer in insects. In the current study, two classes of prenyltransferases (MhieFPPS1 and MhieFPPS2, MhiePFT-β and MhiePF/GGT-α) were identified in the leaf beetle, Monolepta hieroglyphica. Phylogenetic analysis revealed that MhieFPPS1, MhieFPPS2, MhiePFT-β and MhiePF/GGT-α were clustered in one clade with homologous in insects.

Supercapacitively Liquid-Solid Dual-State Optoelectronics.

Photo-transduction of solid-state optoelectronics occurs in semiconductors or their interfaces. Considering the confined active area and interfacial capacitance of solid-state materials, solid-state optoelectronics faces inherent limitations in photo-transduction, especially for bionic vision, and the performance is lower than that of living systems. For example, a photoreceptor generates pA-level photocurrent when absorbing a single photon.
