Abstract

Much research showed that there is phtotobiomodulation on cell apoptosis. The membrane receptor mediated signal transduction mechanism (STM) on photobiomodulation was suggested by Liu et al, and verified by successful applications. In this paper, it was used to study photobiomodulation on cell apoptosis. As the frequency of the absorption light of membrane receptors is greater than the visible light, the membrane absorption of the light is non-resonant, and its transition rate is extraordinarily small, but can be amplified by the coherent state of the identical and independent membrane receptors. The activation coherent states of receptors will activate signal transduction pathway, which was called collective phototransduction. It was shown that collective phototransduction mediated STM was one of the possible mechanisms of photobiomodulation on cell apoptosis.
