Project description:Periodontitis, delineated by the destruction of structures that support teeth, is predominantly propelled by intricate immune responses. Immunomodulatory treatments offer considerable promise for the management of this ailment; however, the modulation of the periodontal immune microenvironment to facilitate tissue regeneration presents a substantial biomedical challenge. Herein, our study investigates the role of Wilms' tumor 1-associating protein (WTAP), a critical m6A methyltransferase, in the immunomodulation of periodontitis and assesses its viability as a therapeutic target. We observed heightened expression of WTAP in macrophages extracted from gingival tissues impacted by periodontitis, with a strong association with M1 polarization. Via loss-of-function experiments, we demonstrated that diminishing WTAP expression precipitates a transition from M1 to M2 macrophage phenotypes amidst inflammatory conditions, thus improving the periodontal immune landscape. Further, RNA sequencing and indirect co-culture assays indicated that suppressing of WTAP expression modulates osteoimmune responses and enhances the osteogenic differentiation of bone marrow stromal cells. The local deployment of adeno-associated virus-shWTAP in murine models of periodontitis robustly validated the therapeutic promise of targeting WTAP in this disease. Collectively, our findings highlight the crucial role of WTAP in orchestrating macrophage-mediated osteoimmune responses and tissue regeneration in periodontitis, proposing novel avenues for immunotherapeutic interventions in its treatment.

Project description:The bone-defect-repair process involves complex interaction between mesenchymal stem cells (MSCs) and immune cells, while the heterogeneity of osteoimmune microenvironment around implanted biomaterials remains elusive. By combining analysis of scRNA-seq and spatial transcriptomics technologies, we revealed that MgphiMSCs subpopulation served as the pioneers during the early stage of biomaterials-mediated bone defect healing process. They performed efficient osteogenic differentiation potential and had close interactions with immune cells. Remarkably, the MgphiMSCs could response to biomaterials-mediated osteoimmune microenvironment, rewired the polarization and osteoclastic differentiation of macrophages via midkine (MDK) signaling pathway. The inhibition of MDK activated the pro-inflammatory programs of macrophages and osteoclastogenesis. Meanwhile, multiple innate and adaptive immune-cell subsets exhibited close crosstalk between MgphiMSCs via SPP1 signaling pathway. These cellular profiles and interactions characterized in this study could broaden our understanding of the functional MSCs subpopulations at the early stage of biomaterial-mediated bone regeneration and provide the basis for the materials-designed strategies that target osteoimmune modulation.

Project description:The fundamental of regeneration process of invertebrates involves the renewal, differentiation and reprogramming of stem cell in an orchestrated manner. It has been known that N6-methyladenosine (m6A) regulates stem cell renewal and differentiation. It is still unclear if m6A is crucial for the regeneration at whole-organism level. Here, we demonstrate that wtap knockdown mediated m6A depletion impairs planarian regeneration upon amputation. The cell cycle related genes displayed decreased m6A while increased expression levels in response to wtap knockdown. The m6A depletion induced phenotypes can be rescued by double-knocking down these genes together with wtap, suggesting that m6A-mediated cell cycle controls planarian regeneration. Further analysis combining the single-cell sequencing unveils a unique neuronal progenitor-like cell type, named NCC and characterized by specific expression of grn, which is indispensable for neuroregeneration. Overall, our study uncovered an essential role of wtap-mediated m6A modification in regulating stem cell population dynamics and homeostasis in terms of general-body regeneration.
