Abstract Since the diseases that cause bone defects are mostly inflammatory diseases, current grafts unable to effectively regulate osteoimmune activity, leading impaired osteogenesis and unfavorable regeneration. In this study, inspired by composition, biomimetic mesoporous bioactive glass nanoparticle (MBG)/bovine serum albumin (BSA) designed for defects. Systematically, MBG/BSA evaluated characterization, bioactivity, anti‐inflammatory, antioxidant osteogenic activity. proved be biocompatible can release ions including calcium silicon in a sustained manner. Furthermore, reprograms macrophage phenotype toward anti‐inflammation is beneficial The antioxidative activity also validated under inflammation mechanism may via interleukin‐4 (IL‐4)/Signal transducer activator of transcription 6 (STAT6) pathway. differentiation mineralization facilitated due improved immunoregulation MBG/BSA. Overall, work suggests with immunomodulatory properties an ideal material regeneration application.

Resveratrol, a polyphenolic compound known for its diverse biological activities, has demonstrated multiple pharmacological effects, including anti-inflammatory, anti-aging, anti-diabetic, anti-cancer, and cardiovascular protective properties. Recent studies suggest that these effects are partly mediated through the regulation of macrophage polarization, wherein macrophages differentiate into pro-inflammatory M1 or anti-inflammatory M2 phenotypes. Our review highlights how resveratrol modulates polarization various signaling pathways to achieve therapeutic effects. For example, can activate senescence-associated secretory phenotype (SASP) pathway inhibit signal transducer activator transcription (STAT3) sphingosine-1-phosphate (S1P)-YAP axes, promoting suppressing thereby inhibiting tumor growth. Conversely, it promote suppress by NF-κB activating PI3K/Akt AMP-activated protein kinase (AMPK) pathways, thus alleviating inflammatory responses. Notably, effect on is concentration-dependent; moderate concentrations tend while higher may favor polarization. This concentration dependence offers new perspectives clinical treatment but also underscores necessity precise dosage control when using resveratrol. In summary, exhibits significant potential in regulating treating related diseases.

Abstract Background Periodontitis and peri-implantitis are chronic inflammatory diseases that contribute to tissue destruction bone loss. Periodontitis is triggered by pathogenic bacteria, while also involves metallic particles, which increase the response. Both conditions linked activation of inflammasomes, such as NLRP3 AIM2, facilitate release pro-inflammatory cytokines like IL-1β IL-18 induce pyroptosis. This study aims investigate AIM2 inflammasomes in macrophages exposed bacterial components, well explore potential interplay between these two signaling pathways. Methods Human THP-1-derived were treated with lipopolysaccharide (LPS) titanium ions evaluate inflammasome activation. secretion, ROS production, mitochondrial DNA pyroptosis assessed. Additionally, deficient used examine roles responses. Results LPS synergistically activated NLRP3, resulting increased Under conditions, was indirectly activated, indicated elevated release. Notably, expression reduced wild-type LPS compared alone, however, NLRP3-deficient cells, following treatment. upregulation cells further inhibition, decreased knockout had a more pronounced effect on reducing secretion knockout, indicating greater role Conclusions This demonstrates components drive both macrophages, highlighting their responses associated periodontitis peri-implantitis. The findings reveal regulatory relationship where absence one can enhance activity other. These results provide new insights into mechanisms underlying inflammasome-mediated inflammation suggest therapeutic targets for managing diseases.

ABSTRACT Aim To evaluate the impact of macrophage depletion on bone loss and inflammatory responses in a mouse model peri‐implantitis, assessing potential as therapeutic strategy. Materials Methods Using 6‐week‐old male C57BL/6 mice, peri‐implantitis was induced by placing silk ligature around osteointegrated dental implants. Mice were divided into three groups: Healthy control (Healthy group); with liposomal phosphate‐buffered saline (PBS clodronate for (CLOD group). Two weeks after placement, micro‐CT, histological real‐time PCR analyses performed to assess density, leukocyte infiltration cytokine levels. Results The CLOD group showed significantly higher bone‐to‐implant contact (74%) volume relative total (79%) compared PBS (53% 54%, respectively) (64% 66%, respectively). Histological analysis revealed reduced counts group. Additionally, TNF‐α IL‐10 levels decreased Conclusion Macrophage effectively reduces inflammation peri‐implantitis. This study highlights targeting macrophages promising approach managing although further research is needed optimize strategies.
