Electromagnetic communication between cells through tunnelling nanotubes

Structures of tunneling nanotubes (TNTs) of circular cross section of 50 and 200 nm and length up to 1 mm form a communication system between cells. Transport of material such as endocytic vesicles, mitochondria, proteins, cytoplasmic molecules, etc. has been experimentally proven. Transfer of electric and electromagnetic energy across TNTs corresponding to electrotechnical processes of excitation, propagation, and amplification in cavity systems is yet in a beginning stage of research. Main features of the Manley-Rowe amplification, Fröhlich nonlinear interaction of coherent electric polar vibrations, and description of cutoff frequency propagating limits in the cavities and limits along periodic structures are analysed. Cells connected by TNTs form a unified coherent cavity system which enables simultaneity and mutual cooperation in multicellular organisms.
