The Spike Glycoprotein of SARS-CoV-2 Binds to β1 Integrins Expressed on the Surface of Lung Epithelial Cells

open access: yesViruses, 2021
The spike glycoprotein attached to the envelope of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) binds to and exploits angiotensin-converting enzyme 2 (ACE2) as an entry receptor to infect pulmonary epithelial cells.

Targeted remodeling of breast cancer and immune cell homing niches by exosomal integrins

open access: yesDiagnostic Pathology, 2020
Exosomes represent an important subset of extracellular vesicles involved in inter-cellular communications in health and diseases. Exosomes secreted from cancer and immune cells travel to the specific tissues containing homing niches.

Conformational flexibility determines the Nf2/merlin tumor suppressor functions

open access: yesMatrix Biology Plus, 2021
The Neurofibromatosis type 2 gene encodes the Nf2/merlin tumor suppressor protein that is responsible for the regulation of cell proliferation. Once activated, Nf2/merlin modulates adhesive signaling pathways and thereby inhibits cell growth.

Sharpin suppresses β1-integrin activation by complexing with the β1 tail and kindlin-1

open access: yesCell Communication and Signaling, 2019
Background Previously sharpin has been identified as an endogenous inhibitor of β1-integrin activation by directly binding to a conserved region in the cytoplasmic tails (CTs) of the integrin β1-associated α subunits. Methods Here we employed biochemical

Integrin-Ligand Interactions in Inflammation, Cancer, and Metabolic Disease: Insights Into the Multifaceted Roles of an Emerging Ligand Irisin

open access: yesFrontiers in Cell and Developmental Biology, 2020
Integrins are transmembrane proteins that mediate cellular adhesion and migration to neighboring cells or the extracellular matrix, which is essential for cells to undertake diverse physiological and pathological pathways.

Twin disc assessment of wheel/rail adhesion [PDF]

open access: yes, 2008
Loss of adhesion between a railway wheel and the track has implications for both braking and traction. Poor adhesion in braking is a safety issue as it leads to extended stopping distances. In traction, it is a performance issue as it may lead to reduced

Mechanotransduction as a major driver of cell behaviour: mechanisms, and relevance to cell organization and future research

open access: yesOpen Biology, 2021
How do cells process environmental cues to make decisions? This simple question is still generating much experimental and theoretical work, at the border of physics, chemistry and biology, with strong implications in medicine.
