Mechanism of Action

Photochemistry studies the fascinating interaction between light and the biological world.

The clinical effect of light therapy stem from the activation of photoreceptors, receptors that possess unique light absorbing molecular structures.  Numerous photoabsorbing structures have been identified in nature:

  • Flavoproteins (phototropin)
  • Porphyrins (tetrapyrrole)
  • Hemoglobin
  • Flavin

Mechanism of Action

Key Aspects

The Model UVL1500 UVLrx Treatment System™ administers three key wavelengths to isolate photoabsorbing entities (referred to as photoreceptors) found within a specific group of cells. When stimulated with light, photoreceptor function changes, which in turn, modulates the biochemical reactions linked to the photoreceptor.

The effect ripples throughout the cell, modulating its behavior and function. According, the Model UVL1500 UVLrx Treatment System™ integrates key wavelengths shown to eradicate foreign pathogens while modulating the immune and circulatory systems.

Following light stimulation, electrons contained within the photoreceptor become excited. The excitation, and subsequent relaxation, of electrons affects the enzyme’s or protein’s chemical behavior. As most enzymes and proteins are embedded within elaborate secondary cascades and positive and negative feedback mechanisms, the behavioral change of a single molecular entity may have far-reaching effects.

The sequence of images below illustrate light’s influence on cell function.

In short, a photochemical mechanism is similar to an agonist drug, in which a specific molecule is targeted to affected its linked biochemical cascade for the purposes of yielding a desired clinical result. Instead of using a drug, the Model UVL1500 UVLrx Treatment System™ administers key wavelengths that target foreign pathogens and the immune and circulatory system.
