Abstract
Neutrophil extracellular traps (NETs) have been the subject of research in the field of innate immunity since they were first described two decades ago. NETs are fibrous network structures released by neutrophils under specific stimuli, including DNA, histones, and a variety of granular proteins. NETs have been widely studied in the fields of infectious and immune diseases, and new breakthroughs have been made in the understanding of disease pathogenesis and treatment. In recent years, studies have found that NETs play an important role in the occurrence and development of osteoarticular diseases. This article reviews the progress in the research of NETs in common osteoarticular diseases such as rheumatoid arthritis, ankylosing spondylitis, gouty arthritis, osteonecrosis of the femoral head, osteoarthritis, and joint fibrosis, including the formation mechanism of NETs and its role in inflammation, joint destruction, pain and other pathological processes. The problems existing in current research are discussed, along with future research directions, to provide a reference for the in-depth study of osteoarticular diseases and the development of new treatment strategies.

Human and Mouse Bone Marrow CD45 + Erythroid Cells Have a Constitutive Expression of Antibacterial Immune Response Signature Genes. Biomedicines 2025; 13:1218. [PMID: 40427045 PMCID: PMC12108605 DOI: 10.3390/biomedicines13051218] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2025] [Revised: 05/15/2025] [Accepted: 05/15/2025] [Indexed: 05/29/2025] Open
Abstract
Introduction: Recent studies have shown that Erythroid progenitor cells exhibit a distinct immunosuppressive and immunoregulatory phenotype associated with the response to bacteria. Methods: The objective of this study was to comprehensively explore the traits of human bone marrow Erythroid cells through protein-protein interaction network analysis using cytokine secretion analysis, and single-cell immunoproteomic analysis using flow cytometry, as well as the re-analysis of publicly available human and mouse bone marrow Erythroid-cell transcriptomic data. Results: Our protein-protein interaction network analysis of human bone marrow Erythroid-cell protein-coding genes identified enrichment in the immune response to lipopolysaccharide, with Calprotectin and Cathepsin G being the main factors. We then mapped the Calprotectin to the CD45+ Erythroid cells of both humans and mice via the analysis of the publicly available scRNA-seq data. Additionally, we observed that human bone marrow Erythroid cells secrete cytokines and chemokines, such as IL-1b, IL-8, and IL-18, which are also mainly involved in the immune response to lipopolysaccharide. We also found that human and mouse bone marrow Erythroid-cell conditional media inhibit bacterial growth in vitro. Discussion: These findings suggest that both human and mouse bone marrow CD45+ Erythroid cells possess the potential to combat pathogenic microbes and thus play a role in innate antimicrobial immunity. Conclusions: CD45+ Erythroid cells are a potent immunoregulatory cell population in both humans and mice.

Innovative nanoparticle-based approaches for modulating neutrophil extracellular traps in diseases: from mechanisms to therapeutics. J Nanobiotechnology 2025; 23:88. [PMID: 39915767 PMCID: PMC11800495 DOI: 10.1186/s12951-025-03195-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2024] [Accepted: 02/02/2025] [Indexed: 02/11/2025] Open
Abstract
Neutrophil extracellular traps (NETs) participate in both host defense and the pathogenesis of various diseases, such as infections, thrombosis, and tumors. While they help capture and eliminate pathogens, NETs' excessive or dysregulated formation can lead to tissue damage and disease progression. Therapeutic strategies targeting NET modulation have shown potential, but challenges remain, particularly in achieving precise drug delivery and maintaining drug stability. Nanoparticle (NP)-based drug delivery systems offer innovative solutions for overcoming the limitations of conventional therapies. This review explores the biological mechanisms of NET formation, their interactions with NPs, and the therapeutic applications of NP-based drug delivery systems for modulating NETs. We discuss how NPs can be designed to either promote or inhibit NET formation and provide a comprehensive analysis of their potential in treating NET-related diseases. Additionally, we address the current challenges and future prospects for NP-based therapies in NET research, aiming to bridge the gap between nanotechnology and NET modulation for the development of novel therapeutic approaches.
