La photobiomodulation is a low-dose form of light therapy that can relieve pain and promote tissue healing and regeneration. Photobiomodulation can now accelerate burn healing, according to a new study.

The research, published in Scientific Reports, notes that photobiomodulation therapy accelerates recovery from burns. Most importantly, it reduces inflammation in mice by activating the Endogenous TGF-beta 1, a protein that controls cell growth and division.

The results can change therapeutic treatments for burns, and that's a big blow. Burns affect more than 6 million people around the world every year, says the principal investigator Praveen Arany, assistant professor of oral biology at the University of Buffalo School of Dental Medicine.

Photobiomodulation: a light bath against burns?

“We effectively use photobiomodulation therapy to support cancer care, age-related macular degeneration and Alzheimer's disease,” says Arany.

A common feature among these disorders is the central role of inflammation. Our work provides evidence for photobiomodulation-activated TGF-beta 1's ability to mitigate burns while promoting tissue regeneration.

The phases of the research

The study measured the effect of photobiomodulation on closure of third-degree burns. The observation lasted for a period of nine days. The treatment activated TGF-beta 1, which stimulated various types of cells involved in healing. These include fibroblasts (the main connective tissue cells of the body. They play an important role in tissue repair, even after burns) and macrophages (immune cells that reduce inflammation. And not only that: they clean cell debris, and fight infections).

The researchers also developed a precise burn healing protocol for photobiomodulation treatments to ensure that the use of the laser does not inadvertently cause further thermal injury.

The efficacy of photobiomodulation in treating pain and stimulating healing has been documented in hundreds of clinical studies and thousands of academic articles. Therapy was recently recommended as a standard treatment to relieve pain from cancer-associated oral mucositis (inflammation and lesions in the mouth).

It is appropriate to say that there is a glimpse ... a light for the cure of many conditions.
