In autoimmune diseases, like vitiligo, the over-protective body's immune system mistakenly attacks stressed-out cells, believing them to be intruders. Specialized ‘killer’ T-cells neutralize these ‘enemies’ - driving autoimmune response and, with it, progressive skin depigmentation.
Current treatments for autoimmune conditions rely on inactivating the 'crazy' immune cells that mistakenly identify and attack the body's own healthy cells. However, a major downside of existing therapies is that they may end up inactivating not just the specific immune cells causing the damage, but also other immune cells that are functioning normally. In case of vitiligo, this would leave the skin exposed to all kinds of diseases and infections.
A new research paper recently published in Nature Biomedical Engineering demonstrate the possibility of deactivating only rogue immune cells, while preserving normal immune cells so they can continue to do their job. The work of a team from University of Utah Health in Salt Lake City focuses on programmed cell death protein cells that play a key role in regulating the immune response. The researchers tested the new approach in a mouse model of diabetes type I and multiple sclerosis, and saw encouraging results. The lead researcher of the study, Peng Zhao, Ph.D., says "If we can generate the human version of therapeutics, I think we could make a huge impact in treating an autoimmune disease."
- Will it spread?
Vitiligo activity may vary considerably from person to person. In a good number of patients the disease goes on for 3-4 years and then it settles down, with one or two stubborn...
- Vitiligo and hearing loss: any connection?
In short, NO. Recent research shows no relationship between a degree of skin depigmentation and hearing loss severity in vitiligo patients. The results of this study showed tha...
- Isn't it just a cosmetic disorder?
Contrary to popular belief, vitiligo is not a cosmetic disorder but a systemic disease affecting the largest body organ and other vital systems. For more than 1.6 million peop...

Though it is not always easy to treat vitiligo, there is much to be gained by clearly understanding the diagnosis, the future implications, treatment options and their outcomes.
Many people deal with vitiligo while remaining in the public eye, maintaining a positive outlook, and having a successful career.Copyright (C) Bodolóczki Júlia
By taking a little time to fill in the anonymous questionnaire, you can help researchers better understand and fight vitiligo.
