We investigated the effects of low-level Er:YAG laser irradiation on proliferation and alternations in early gene expression gingival fibroblasts. Mice primary fibroblasts were irradiated with an (1.8, 3.9, 5.8 J/cm2). Irradiation at 3.9 J/cm2 promoted cell without significant changes lactate dehydrogenase or Hspa1a expression. Three hours after J/cm2, Fn1 level was significantly increased. RNA-seq identified 15 differentially expressed genes between non-irradiated cells, some which belonged to immediate (IEGs).

The extracellular matrix (ECM) is a complex non-cellular three-dimensional macromolecular network present within all tissues and organs, forming the foundation on which cells sit, composed of proteins (such as collagen), glycosaminoglycans, proteoglycans, minerals, water. ECM provides fundamental framework for cellular constituents tissue biochemical support to surrounding cells. highly dynamic structure that constantly being remodeled. Matrix metalloproteinases (MMPs) are among most important proteolytic enzymes capable degrading molecules. MMPs play relevant role in physiological well pathological processes; participate embryogenesis, morphogenesis, wound healing, remodeling, therefore, their impaired activity may result several problems.

ABSTRACT Periodontitis involves hyperactivated stromal cells that recruit immune cells, exacerbating inflammation. This study presents an ATP-responsive metal–organic framework (Mg/Zn-MOF) designed for periodontitis treatment, utilizing ion interference to modulate responses and prevent tissue destruction. Addressing the challenges of synergistic effects targeted delivery faced by traditional immunomodulatory nanomaterials, Mg/Zn-MOF system is activated extracellular ATP—a pivotal molecule in pathology—ensuring release. Magnesium zinc ions released from synergistically inhibit membrane pore formation attenuating Gasdermin D (GSDMD) expression activation. action curtails pyroptosis, lactate dehydrogenase IL-1β release, thwarting onset inflammatory cascades. Mechanistically, intervenes both NLRP3/Caspase-1/GSDMD Caspase-11/GSDMD pathways mitigate pyroptosis. In vivo assessments confirm its effectiveness diminishing cell infiltration preserving collagen integrity, thereby safeguarding against periodontal damage bone loss. investigation highlights promise ion-interference strategies immunotherapy, representing a significant stride developing therapeutic approaches.

Oral diseases such as dental caries, periodontitis, and oral cancer are prevalent present significant challenges to global public health. Although these typically treated through procedures like preparation resin filling, scaling root planning, or surgical excision, interventions often not entirely effective, postoperative drug therapy is usually required. Traditional treatments, however, limited by factors poor penetration, side effects, the development of resistance. As a result, there growing need for novel delivery systems that can enhance therapeutic efficacy, reduce improve treatment outcomes. In recent years, drug-loaded vesicles, liposomes, polymersomes, extracellular vesicles (EVs), have emerged promising platforms due their high encapsulation efficiency, controlled release properties, excellent biocompatibility. This review provides an in-depth examination characteristics, advantages, limitations in context disease treatment. It further explores reasons advantages discusses specific applications, prospects, strategies optimizing vesicle-based improved clinical

Abstract Objectives: Clinical studies have confirmed that galectin-3 (Gal-3) levels are significantly elevated in periodontitis patients. The present study aimed to explore the effects of Gal-3 inhibition on periodontal inflammation vitro and vivo. Methods: Human gingival fibroblasts (HGFs) with or without knockdown were stimulated by lipopolysaccharide (LPS), a ligation-induced mouse model treated inhibitor was established. Hematoxylin–eosin (H&E) immunohistochemistry (IHC) staining used evaluate tissues. Quantitative real-time polymerase chain reaction (qRT-PCR) enzyme-linked immunosorbent assay (ELISA) detect Gal-3, interleukin (IL)-6, IL-8, C-C motif ligand 2 (CCL2) expression. Immunofluorescence western blotting NF-κB ERK signaling pathway activation. Micro-computed tomography analyse degree bone loss.
