Special Issue Information

Dear Colleagues,

Cells are dynamic systems that constantly experience and respond to physical forces from their environment. These mechanical cues regulate the cellular architecture, signaling pathways, and gene expression, ultimately influencing cell function, tissue organization, and disease progression. Understanding how cells sense, transduce, and generate mechanical forces—the essence of mechanobiology—is fundamental in unraveling the physical principles that underlie biological processes.

Over the past several years, mechanobiology has grown from a niche concept into a well-established field that bridges physics and biology. This Special Issue will explore the molecular and biophysical mechanisms that define the mechanobiology of the cell. Our objective is to gather research on the following topics:

  • Cellular responses to mechanical stimuli, including substrate ​properties and externally applied forces;
  • Mechanotransduction pathways linking forces and molecular signaling;
  • Roles of the cytoskeleton, focal adhesions, and extracellular matrix in mediating cellular mechanics;
  • Nuclear and chromatin mechanics in cellular regulation;
  • Mechanobiological mechanisms in development, tissue homeostasis, and disease;
  • Emerging tools and methods for studying the mechanics of living systems.

We welcome original research articles and comprehensive reviews offering new insights into how mechanical and molecular processes intersect to shape cellular behavior. Furthermore, we aim to feature emerging experimental and computational technologies that can advance our understanding of mechanobiological systems.

Ultimately, this Special Issue will serve as a platform for interdisciplinary discussion among researchers in cell biology, biophysics, and molecular sciences. By bringing together diverse perspectives, we hope to advance our knowledge of how mechanical forces contribute to cellular life.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Mechanical signals play key roles in the regulation of epidermal homeostasis and regeneration after injury. Integrins are key components of focal adhesions, and these complexes are major contributors to mechanotransduction. In keratinocytes, integrin-linked kinase (ILK) modulates essential processes for epidermal homeostasis and wound repair. However, its functions in the transduction of mechanical stimuli have remained virtually unexplored. In this study, we characterized epidermal tissues and primary keratinocytes from mice with epidermis-restricted inactivation of the Ilk gene (ILK-KO). ILK-deficient epidermis exhibits abnormalities in key components of mechanotransduction cascades, including disruptions in hemidesmosomal Collagen XVII immunoreactivity at the dermal–epidermal junction, and marked reduction in the nuclear localization of the mechanosensitive transcriptional regulator YAP. In wild-type (ILK+), but not in ILK-KO-cultured keratinocytes, exposure to cyclic bidirectional strain induced marked F-actin cytoskeletal rearrangements, characterized by the assembly of thick cortical actin bundles and stress fibers, as well as YAP nuclear translocation and transcriptional activity. Exposure to mechanical strain was additionally accompanied by differential changes in miRNA expression between ILK+ and ILK-KO cells. These findings reveal multiple and previously unappreciated key regulatory roles for ILK in epidermal keratinocyte responses to mechanical signals. Full article

The most recent research has demonstrated that oscillatory nano-structures found on the lumenal walls of deep cerebral veins likely contribute significantly to the regulation of the function of deep cerebral veins. The oscillatory nano-structures consist of very small, intricately organized “nanoflaps,” each consisting of a hinge element with an attached lipid bilayer architecture. These nanoflaps have distinct mechanical properties, are in close proximity to mechanically sensitive protein assemblies, and therefore it is hypothesized that the nanoflaps generate rhythmic oscillations that control the distribution of both pressure and fluid flow through the veins and also regulate the metabolic condition of the surrounding tissue. In addition, the behavior of the nanoflaps indicate that there exists a hitherto unappreciated level of venous biomechanics at the nanometer scale that regulates the hydraulic stability of the veins and may also contribute to the structural integrity of the surrounding tissues. The purpose of this review is to provide a theoretical framework for understanding the recent discoveries of the structure, oscillation and hydrodynamic effects of nanoflaps, including resonance drift, waveform irregularity, and multi-scale biomechanical interactions. Additionally, this review will present the idea that disruption of the normal oscillatory processes that occur in the nanoflaps may lead to the development of abnormal micro-environments in the early stages of neurodegenerative diseases, abnormalities of compliance, dysautonomic states, traumatic injury and micro-circulatory stress. Finally, this review will describe several pharmacological strategies that may be used to stabilize the oscillations generated by the nanometer-scale oscillatory nano-structure by modifying the torque applied to the hinge, the viscoelasticity of the membrane and the feedback pathways for mechanotransduction.
