An investigation of gecko attachment on wet and rough substrates leads to the application of surface roughness power spectral density analysis

Scientific Reports, 2022
The roughness and wettability of surfaces exploited by free-ranging geckos can be highly variable and attachment to these substrates is context dependent (e.g., presence or absence of surface water). Although previous studies focus on the effect of these

Probing mechanical interaction of immune receptors and cytoskeleton by membrane nanotube extraction

Scientific Reports, 2023
The role of force application in immune cell recognition is now well established, the force being transmitted between the actin cytoskeleton to the anchoring ligands through receptors such as integrins. In this chain, the mechanics of the cytoskeleton to

miRNA-200c-3p targets talin-1 to regulate integrin-mediated cell adhesion

Scientific Reports, 2021
The ability of integrins on the cell surface to mediate cell adhesion to the extracellular matrix ligands is regulated by intracellular signaling cascades.

Controlling T cells spreading, mechanics and activation by micropatterning

Scientific Reports, 2021
We designed a strategy, based on a careful examination of the activation capabilities of proteins and antibodies used as substrates for adhering T cells, coupled to protein microstamping to control at the same time the position, shape, spreading ...

Irisin supports integrin-mediated cell adhesion of lymphocytes

Biochemistry and Biophysics Reports, 2021
Irisin, a myokine released from skeletal muscle, has recently been found to act as a ligand for the integrins αVβ5, αVβ1, and α5β1 expressed on mesenchymal cells, thereby playing an important role in the metabolic remodeling of the bone, skeletal muscle ...

Potential Roles of Muscle-Derived Extracellular Vesicles in Remodeling Cellular Microenvironment: Proposed Implications of the Exercise-Induced Myokine, Irisin

Frontiers in Cell and Developmental Biology, 2021
Extracellular vesicles (EVs) have emerged as key players of intercellular communication and mediate crosstalk between tissues. Metastatic tumors release tumorigenic EVs, capable of pre-conditioning distal sites for organotropic metastasis.

EpCAM promotes endosomal modulation of the cortical RhoA zone for epithelial organization

Nature Communications, 2021
The organization and force-generating property of actomyosin dictate the plasticity and behaviour of cells but the spatio-temporal regulation of this network is unclear.

The mitochondrial outer membrane protein SYNJ2BP interacts with the cell adhesion molecule TMIGD1 and can recruit it to mitochondria

BMC Molecular and Cell Biology, 2020
Background Transmembrane and immunoglobulin domain-containing protein 1 (TMIGD1) is a recently identified cell adhesion molecule which is predominantly expressed by epithelial cells of the intestine and the kidney. Its expression is downregulated in both
