Interleukin-1 receptor-related kinase (IRAK4) is a widely expressed serine/threonine kinase involved in the regulation of innate immunity. IRAK4 plays a pivotal role as a key kinase within the downstream signaling pathway cascades of interleukin-1 receptors (IL-1R) and Toll-like receptors (TLRs). The signaling pathways orchestrated by IRAK4 are integral to inflammatory responses, and its overexpression is implicated in the pathogenesis of inflammatory diseases, autoimmune disorders, and cancer.

Intestinal epithelial cell NCoR deficiency ameliorates obesity and metabolic syndrome.

Acta Pharm Sin B

December 2024

State Key Laboratory of Bioactive Substance and Function of Natural Medicines, Institute of Materia Medica, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing 100050, China.

Nuclear receptor corepressor (NCoR1) interacts with various nuclear receptors and regulates the anabolism and catabolism of lipids. An imbalance in lipid/energy homeostasis is also an important factor in obesity and metabolic syndrome development. In this study, we found that the deletion of NCoR1 in intestinal epithelial cells (IECs) mainly activated the nuclear receptor PPAR and attenuated metabolic syndrome by stimulating thermogenesis.

The elderly population in China faces a significant burden of influenza, but the influenza vaccination rate among this group remains far below international recommended standards due to factors such as the underdeveloped adult immunization service system, high vaccination costs, and insufficient awareness among both the elderly and healthcare professionals. It is recommended that China implement a free or reimbursement policy influenza vaccination for elderly in border regions, improve the adult immunization service system, enhance the awareness of healthcare professionals and the elderly, and strengthen the research and post-vaccination monitoring of vaccines tailored to the elderly population to increase the influenza vaccination rate among the elderly.

Defect-Induced Electron Localization Promotes D2O Dissociation and Nitrile Adsorption for Deuterated Amines.

Angew Chem Int Ed Engl

January 2025

Tianjin University, Department of Chemistry, #92, Weijin Road, Nankai District, Department of Chemistry, School of Science, Tianjin University, 300072, Tianjin, CHINA.

Electrochemical reductive deuteration of nitriles is a promising strategy for synthesizing deuterated amines with D2O as the deuterated source. However, this reaction suffers from high overpotentials owing to the sluggish D2O dissociation kinetics and high thermodynamic stability of the C≡N triple bond. Here, low-coordinated copper (LC-Cu) is designed to decrease the overpotential for the electrosynthesis of the precursor of Melatonin-d4, 5-methoxytryptamine-d4, by 100 mV with a 68% yield (Faraday efficiency), which is 4 times greater than that of high-coordinated copper (HC-Cu).

Immunogenic cell death (ICD) of tumor cells, which is characterized by releasing immunostimulatory "find me" and "eat me" signals, expressing proinflammatory cytokines and providing personalized and broad-spectrum tumor antigens draws increasing attention in developing a tumor vaccine. In this study, we aimed to investigate whether the influenza virus (IAV) is efficient enough to induce ICD in tumor cells and an extra modification of IAV components such as hemeagglutinin (HA) will be helpful for the ICD-induced cells to elicit robust antitumor effects; in addition, to evaluate whether the membrane-engineering polylactic coglycolic acid nanoparticles (PLGA NPs) simulating ICD immune stimulation mechanisms hold the potential to be a promising vaccine candidate, a mouse melanoma cell line (B16-F10 cell) was infected with IAV rescued by the reverse genetic system, and the prepared cells and membrane-modified PLGA NPs were used separately to immunize the melanoma-bearing mice. IAV-infected tumor cells exhibit dying status, releasing high mobility group box-1 (HMGB1) and adenosine triphosphate (ATP), and exposing calreticulin (CRT), IAV hemeagglutinin (HA), and tumor antigens like tyrosinase-related protein 2 (TRP2).

The emerging combination of chemotherapy and radionuclide therapy has been actively investigated to overcome the limitations of monotherapy and augment therapeutic efficacy. However, it remains a challenge to design a single delivery vehicle that can incorporate chemotherapeutics and radionuclides into a compact structure. Here, a chelator DOTA- or NOTA-modified Evans blue conjugated camptothecin molecule (EB-CPT) nanoprodrug was synthesized, which could self-assemble into nanoparticles due to its inherent amphiphilicity.

Extracellular matrix (ECM)-based small-diameter vascular grafts (SDVGs, inner diameter (ID) < 6 mm) hold great promise for clinical applications. However, existing ECM-based SDVGs suffer from limited donor availability, complex purification, high cost, and insufficient mechanical properties. SDVGs with ECM-like structure and function, and good mechanical properties were rapidly prepared by optimizing common materials and preparation, which can improve their clinical prospects.

ETV7 limits the antiviral and antitumor efficacy of CD8 T cells by diverting their fate toward exhaustion.

Nat Cancer

January 2025

State Key Laboratory of Molecular Oncology, School of Life Sciences, Tsinghua-Peking Center for Life Sciences, Tsinghua University, Beijing, China.

Terminal exhaustion is a critical barrier to antitumor immunity. By integrating and analyzing single-cell RNA-sequencing and single-cell assay for transposase-accessible chromatin with sequencing data, we found that ETS variant 7 (ETV7) is indispensable for determining CD8 T cell fate in tumors. ETV7 introduction drives T cell differentiation from memory to terminal exhaustion, limiting antiviral and antitumor efficacy in male mice.
