Cell to cell hijacking: Role of membrane nanotubes

Asian Journal of Medical Sciences, 2022
Cell to Cell communications is the pivot for life processes. Any event that disrupts this leads to the loss of physiological function, eventually leading to cell death.

HGF/c-Met/β1-integrin signalling axis induces tunneling nanotubes in A549 lung adenocarcinoma cells

Life Science Alliance, 2023
Interactions between hepatocyte growth factor (HGF), the c-Met receptor, and β1-integrin induce tunneling nanotubes in A549 cells; paxillin and the downstream MAPK and PI3K pathways and the Arp2/3 complex drive HGF-induced TNT formation.

Tunneling Nanotubes: Intimate Communication between Myeloid Cells

Frontiers in Immunology, 2018
Tunneling nanotubes (TNT) are dynamic connections between cells, which represent a novel route for cell-to-cell communication. A growing body of evidence points TNT towards a role for intercellular exchanges of signals, molecules, organelles, and ...

Perspectives of cellular communication through tunneling nanotubes in cancer cells and the connection to radiation effects

Radiation Oncology, 2019
Direct cell-to-cell communication is crucial for the survival of cells in stressful situations such as during or after radiation exposure. This communication can lead to non-targeted effects, where non-treated or non-infected cells show effects induced ...

Effect of Graphene and Carbon Nanotubes on the Thermal Conductivity of WC–Co Cemented Carbide

Metals, 2019
In recent years, it has been found that the service life of cemented carbide shield machine tools used in uneven soft and hard strata is substantially reduced in engineering practice. The study found that thermal stress is the main reason for the failure
