This past few years have heralded remarkable times for intermediate filaments with new revelations of their structural properties that has included the first crystallographic-based model of vimentin to build on the experimental data of intra-filament interactions determined by chemical cross-linking. Now with these and other advances on their assembly, their biomechanical and their cell biological properties outlined in this review, the exploitation of the biomechanical and structural properties of intermediate filaments, their nanocomposites and biomimetic derivatives in the biomedical and private sectors has started.

Precisely crafted hierarchical architectures found in naturally derived biomaterials underpin the exceptional performance and functionality showcased by the host organism. In particular, layered helical assemblies composed of cellulose, chitin, or collagen serve as the foundation for some of the most mechanically robust and visually striking natural materials. By utilizing structured materials in additive manufacturing techniques such as extrusion-based 3D printing, the intrinsic deformation process can be used to implement bottom-up design of printed constructs, offering the potential to create intricate macroscale geometries with embedded nanoscale functionality.

Objectives: Head and neck malignancies (HNMs) encompass a variety of cancers that affect the oral and para-oral tissues, the most common of which are squamous cell carcinomas. Radiotherapy is commonly used to treat these cancers, often involving radiation exposure to the salivary glands. This study aims to investigate the early impacts of radiotherapy on the internal microstructure of the salivary gland cells and identify which gland exhibits the highest level of radiosensitivity.

The epithelial-to-mesenchymal transition (EMT) is a common feature in early cancer invasion. Increased vimentin is a canonical marker of the EMT; however, the role of vimentin in EMT remains unknown. To clarify this, we induced EMT in lung cancer cells with TGF-β1, followed by treatment with the vimentin-targeting drug ALD-R491, live-cell imaging, and quantitative proteomics.

Background/objectives: KRT23 was recently discovered as an epithelial-specific intermediate filament protein in the type I keratin family. Many studies have underlined keratin's involvement in several biological processes as well as in the pathogenesis of different diseases. Specifically, KRT23 was reported to affect the structural integrity of epithelial cells and to trigger cellular signaling leading to the onset of cancer.
