Trojan horses and tunneling nanotubes enable α-synuclein pathology to spread in Parkinson disease.
PLoS Biology, 2021 In Parkinson disease (PD), Lewy bodies (LBs) form in the gut or nose and spread into the midbrain. A study in this issue indicates that the spread is due to lysosomes "infected" with prion-like alpha-synuclein (α-syn) transmitting from cell to cell via ...

Nonequilibrium Tunneling Spectroscopy in Carbon Nanotubes [PDF]
Physical Review Letters, 2009 We report measurements of the non-equilibrium electron energy distribution in carbon nanotubes. Using tunneling spectroscopy via a superconducting probe, we study the shape of the local electron distribution functions, and hence energy relaxation rates, in nanotubes that have bias voltages applied between their ends.

Tunneling nanotubes: Reshaping connectivity
Current Opinion in Cell Biology, 2021 Tunneling nanotubes (TNTs), open membranous channels between connected cells, represent a novel direct way of communication between distant cells for the diffusion of various cellular material, including survival or death signals, genetic material, organelles, and pathogens.

Peering into tunneling nanotubes-The path forward. [PDF]
EMBO J, 2021 The identification of Tunneling Nanotubes (TNTs) and TNT-like structures signified a critical turning point in the field of cell-cell communication. With hypothesized roles in development and disease progression, TNTs' ability to transport biological cargo between distant cells has elevated these structures to a unique and privileged position among ...

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.

Carbon Nanotube Based Magnetic Tunnel Junctions [PDF]
Physical Review Letters, 2000 Spin-coherent quantum transport in carbon nanotube magnetic tunnel junctions was investigated theoretically. A spin-valve effect is found for metallic, armchair tubes, with a magneto-conductance ratio ranging up to 20%. Because of the finite length of the nanotube junctions, transport is dominated by resonant transmission. The magnetic tunnel junctions
