Abstract:
:After 50 years of studies on photobiomodulation (PBM), there is still so much to investigate to understand the laser light-nonplant cells interactions. The current scientific knowledge allows to say that the phenomena induced by PBM are based on cellular pathways that are the key points of cell life. The mitochondria chromophores, also present on the bacterial membrane, the calcium channels, ion that regulates the life-and-death cellular processes, as well as the TRP family, whose genes have been found in protozoa and suggest that its basic mechanism evolved long before the appearance of animals, seem to be elective targets in photobiomodulatory events by wavelengths from 600 up to 980 nm. The ambiguous resulting cellular communication way, mediated by ATP, ROS and/or calcium, leads to cell manipulation, which modifies its metabolism and whose response connects all life-forms from bacteria to vertebrates. Because of the Giano-Bifronte features of ROS and calcium, as well as the fine balance of energetic mitochondrial processes, whose alteration is responsible for several diseases, the PBM can show unpredictable results and it requires scrupulous approach to avoid cellular damages. However, when carefully applied, PBM is able to improve nonhealthy cell's responses and represents a reliable support in human and veterinary medicine.
