Pro- and Anti-inflammatory Genes Expression During the Healing of Biological Tissues after Exposure to 2- micron Laser Radiation

We present the results on the expression of pro-and anti-inflammatory genes during the healing process of mice's muscle and skin tissues after exposure to continuous-wave laser radiation of an all-fiber holmium laser at a wavelength of 2.1 µm with different powers. A significantly high level of pro-inflammatory cytokine expression in tissues persisted until the 21st day after exposure to a power of 1.5 W, in contrast to 1 W exposure where a significant maximum was noted only on the 3rd day.
