A Multifunctional miRNA Delivery System Based on Tetrahedral Framework Nucleic Acids for Regulating Inflammatory Periodontal Ligament Stem Cells and Attenuating Periodontitis Bone Loss.

Periodontitis is a chronic inflammatory disease that leads to periodontal tissue damage and tooth loss. Therefore, controlling inflammatory bone loss and promoting osteogenesis is a crucial challenge clinically. MicroRNA (miRNA) based gene therapy has shown substantial prospects in recent years, but its application has been limited due to structural instability and easy degradation by enzymes.

A Mitochondrial Nanoguard Modulates Redox Homeostasis and Bioenergy Metabolism in Diabetic Peripheral Neuropathy.

As a major late complication of diabetes, diabetic peripheral neuropathy (DPN) is the primary reason for amputation. Nevertheless, there are no wonder drugs available. Regulating dysfunctional mitochondria is a key therapeutic target for DPN.

Nano shield: a new tetrahedral framework nucleic acids-based solution to radiation-induced mucositis.

Radiation-induced oral mucositis (RIOM) is considered to be one of the most important public health problems today, affecting the overall well-being of millions of patients who have received radiotherapy. Nevertheless, the field of preventing and treating RIOM is still widely unexplored. Curcumin (Cur) with its promising anti-inflammatory and antioxidant properties is accompanied with obstacles in application, including poor dissolubility, instability and low bioavailability.

The alteration of A disintegrin and metalloproteinase with thrombospondin motifs (ADAMTS) in the knee joints of osteoarthritis mice.

The A disintegrin and metalloproteinase with thrombospondin motifs (ADAMTS) family is gradually being recognized as an important family of mediators that, along with the matrix metalloproteinases (MMPs), control the degradation process in osteoarthritis (OA). The objective of this study was to uncover the detailed alterations of ADAMTS1, ADAMTS2, and ADAMTS5 in the knee joint of OA mice. The OA model was established by anterior cruciate ligament transection (ACLT) on the knee joints of C57BL/6 J mice.

Exosomal cargoes in OSCC: current findings and potential functions.

Oral squamous cell carcinoma (OSCC) is the most prevalent malignancy in head and neck cancer, with high recurrence and mortality. Early diagnosis and efficient therapeutic strategies are vital for the treatment of OSCC patients. Exosomes can be isolated from a broad range of different cell types, implicating them as important factors in the regulation of human physiological and pathological processes.

Transmissible Endoplasmic Reticulum Stress: A Novel Perspective on Tumor Immunity.

As the first compartment of the protein secretory pathway, the endoplasmic reticulum (ER) acts as a protein synthesis factory, maintaining proteostasis and ER homeostasis. However, a variety of intrinsic and extrinsic perturbations, such as cancer, can disrupt the homeostasis and result in a large accumulation of misfolded/unfolded proteins in the ER lumen, thereby provoking a specific cellular state addressed as "ER stress". Then the unfolded protein response (UPR), an adaptive signaling pathway, is triggered to address the stress and restore the homeostasis.

Spatial Distributions, Characteristics, and Applications of Craniofacial Stem Cells.

Stem cells play an irreplaceable role in the development, homeostasis, and regeneration of the craniofacial bone. Multiple populations of tissue-resident craniofacial skeletal stem cells have been identified in different stem cell niches, including the cranial periosteum, jawbone marrow, temporomandibular joint, cranial sutures, and periodontium. These cells exhibit self-renewal and multidirectional differentiation abilities.
