Paper Abstract

More than one function of a cell can be influenced by low intensity laser (LIL) irradiation, but the others remained unchanged when one function of the cell was altered by LIL irradiation. This phenomenon has been explained by the signal transduction mechanism (STM) on LIL biomodulation. It has been shown in this paper, the membrane receptors collectively mediate STM; as the frequency of the absorption light of membrane receptors is greater than the one of visible laser irradiation, the membrane absorption of visible 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 of a pathological cell.
