Membrane-type 1 matrix metalloproteinase (MT1-MMP) is a type I transmembrane proteinase that belongs to the matrix metalloproteinase (MMP) family. It is a potent modifier of cellular microenvironment and promotes cell migration and invasion of a wide variety of cell types both in physiological and pathological conditions. It promotes cell migration by degrading extracellular matrix on the cell surface and creates a migration path, by modifying cell adhesion property by shedding cell adhesion molecules to increase cell motility, and by altering cellular metabolism. Thus, MT1-MMP is a multifunctional cell motility enhancer. In this review, we will discuss the current understanding of the proteolytic and non-proteolytic mechanism of MT1-MMP-dependent cell migration.

At present, flexible sensors are a hot spot in research and experimental development, but the research on flexible sensors that can be used for human motion monitoring still needs to be deepened. In this work, the green material cellulose acetate (CA) was used as the matrix material, the film was made by electrospinning, crushed by a cell grinder and sodium alginate (SA) was added to promote the uniform dispersion of nanofibers in water, and then methyltrimethoxysilane (MTMS) and MXene nanosheet dispersion were added to make it hydrophobic and good conductivity, and the aerogel precursor solution was prepared, and then the CA/SA/MTMS/MXene aerogel with directional holes was prepared by directional freeze-drying. As a flexible sensor material, it can be used for human wear, monitoring the electrical signals generated by the movement of human joints and other parts, and can still maintain a current of about 0.

Background: Standard treatment for glioblastoma includes chemotherapy, alkylating agents such as temozolomide (TMZ); however, MGMT resistance leads to recurrence. Demethoxycurcumin (DMC) has been reported to inhibit cancer cell growth, induce apoptosis, and prevent metastasis in different cancer models. We investigated the DMC-induced apoptosis and autophagy via inhibition of the AKT/mTOR pathway in human glioma U87MG and T98G cell lines.

Hyperglycemia-induced oxidative stress and inflammation critically impair diabetic bone defect repair. Here, a radially oriented microchannel scaffold (D-GSH@QZ) was developed via a directional freezing technique integrated with photo-cross-linking strategies. The scaffold was fabricated from gelatin methacryloyl, silk fibroin methacryloyl, and nanohydroxyapatite (HAp) to mimic the natural bone matrix, while incorporating quercetin-loaded ZIF-8 nanoparticles (Qu@ZIF-8) for pathological microenvironment modulation.

Unlabelled: Dendritic cells (DCs) are the primary inducers of immunity induced by infection or vaccination. To stimulate durable T cell-mediated immunity, multiple DC activities are required. DCs must present antigen, express costimulatory molecules, and secrete inflammatory cytokines to direct T cell activation.

Background: The factors contributing to a poor response to subthalamic nucleus deep brain stimulation (STN-DBS) in Parkinson's disease (PD) are not yet fully understood. Accordingly, predicting the outcome might be challenging particularly in those who display an optimal response to the Levodopa challenge test.
Objective: To determine which factors may contribute to poor outcome of STN-DBS in PD.
