PBM acts primarily through the activation of cytochrome c oxidase, a key mitochondrial enzyme. Nitric oxide plays a crucial role in mitochondrial function by modulating cytochrome c oxidase activity, and PBM can enhance nitric oxide signaling, thereby improving mitochondrial respiration and cellular health.
At the cellular level, PBM influences a variety of processes, including the regulation of calcium ions, which are essential for cell signaling, proliferation, and differentiation. PBM can also activate light sensitive ion channels at specific wavelengths, leading to increased calcium ion influx and modulation of neural activity.
Gene expression changes and stem cell differentiation are mediated in part by the activation of transcription factors through PBM, which leads to enhanced mitochondrial biogenesis, antioxidant activity, and tissue repair. In particular, PBM has been shown to promote the proliferation and differentiation of mesenchymal stem cells, supporting tissue regeneration.
The cellular mechanisms underlying PBM include a range of molecular mechanisms, such as the modulation of mitochondrial activity, regulation of cytokine production, and changes in gene expression.

Light sources used in PBM include red light and near infrared light, each with distinct roles: red light primarily activates mitochondrial pathways at shallower tissue depths, while near infrared light penetrates deeper and is effective in activating cytochrome c oxidase for enhanced ATP production.

Human Cells and Brain Function: The Biological Foundation
Human cells are the building blocks of all tissues and organs, and their health is fundamental to optimal brain function. In the brain, billions of specialized cells called neurons work together to support cognitive processes such as perception, memory, attention, and decision-making. The intricate communication between these cells underpins everything from basic sensory input to complex thought and behavior.

A key molecular mechanism behind these effects is the activation of cytochrome c oxidase, a crucial enzyme in the mitochondrial respiratory chain. When stimulated by laser irradiation, cytochrome c oxidase boosts the production of ATP, the primary energy currency of the cell. This increase in cellular energy supports a range of vital functions, from cell proliferation to the repair of damaged tissue. Additionally, LLLT can modulate the production of reactive oxygen species (ROS), which act as signaling molecules to trigger beneficial cellular processes involved in tissue regeneration and immune response.
