Tissues consist of cells and their surrounding extracellular matrix (ECM). Cell-ECM interactions play crucial roles in embryonic development, differentiation, tissue remodeling, and diseases including fibrosis and cancer. Recent research advances in characterizing cell-matrix interactions include detailed descriptions of hundreds of ECM and associated molecules, their complex intermolecular interactions in development and disease, identification of distinctive modes of cell migration in different 3D ECMs, and new insights into mechanisms of organ formation. Exploring the roles of the physical features of different ECM microenvironments and the bidirectional regulation of cell signaling and matrix organization emphasize the dynamic nature of these interactions, which can include feedback loops that exacerbate disease. Understanding mechanisms of cell-matrix interactions can potentially lead to targeted therapeutic interventions.

Glioblastoma (GBM) is a highly lethal malignant brain tumor with poor survival rates, and chemoresistance poses a significant challenge to the treatment of patients with GBM. Here, we show that transketolase (TKT), a metabolic enzyme in the pentose phosphate pathway (PPP), attenuates the chemotherapy sensitivity of glioma cells in a manner independent of catalytic activity. Mechanistically, chemotherapeutic drugs can facilitate the translocation of TKT protein from the cytosol into the nucleus, where TKT physically interacts with XRN2 to regulate the resolution and removal of R-loops.

Neuroinflammation is a complex and multifaceted process that involves dynamic interactions among various cellular and molecular components. This sophisticated interplay supports both environmental adaptability and system resilience in the central nervous system (CNS) but may be disrupted during neuroinflammation. In this article, we first characterize the key players in neuroimmune interactions, including microglia, astrocytes, neurons, immune cells, and essential signaling molecules such as cytokines, neurotransmitters, extracellular matrix (ECM) components, and neurotrophic factors.

Aims: This study investigated the effect of injection of adipose stem cells (ASCs) on the expression of type VII and VIII collagen in Wistar rat's gingiva. Adipose stem cells can modulate the immune system, angiogenesis, wound healing, and extracellular matrix (ECM) remodeling.
Materials And Methods: Ten Wistar rats aged three months were divided into two groups: the treatment group and the control group.

This study provides a comprehensive investigation of antimicrobial additives (ZnO/AgNPs and SiO/AgNPs) on the properties of biodegradable ternary blends composed of poly(hydroxybutyrate) (PHB), poly(lactic acid) (PLA), and polycaprolactone (PCL) by examining the morphology, thermal stability, crystallinity index, and cell viability of these blends. Overall, transmission electron microscopy (TEM) analysis revealed that AgNPs and SiO exhibited comparable sizes, whereas ZnO was significantly larger, which influences their release profiles and interactions with the blends. The addition of antimicrobials influences the rheology of the blends, acting as compatibilizers by reducing the intermolecular forces between biopolymers.
