Scleroderma Treatment Breakthrough?
Posted By American Med Spa Association, Friday, November 4, 2016
New and ongoing research at Hospital for Special Surgery (HSS) in New York City has identified a possible mechanism behind the fibrosis that occurs in scleroderma – a mechanism that may one day lead to a treatment for the disease.
The findings appear in the Journal of Clinical Investigation.
In laboratory research, adipose-derived stromal cells (ADSCs) are reduced in the layer of fat sitting under the skin, and the loss of these ADSCs may contribute to the skin fibrosis of scleroderma.
Moreover, the survival of the ADSCs that do remain beneath the skin in scleroderma are dependent on dendritic cells which release a compound called lymphotoxin B that promotes ADSC survival. When antibodies that stimulate the lymphotoxin B receptor were administered with ADSCs to replenish the lost supply, ADSC survival was increased, suggesting a means for reversing the fibrosis of the skin.
“Injecting ADSCs is being tried in scleroderma; the possibility of stimulating the lymphotoxin B pathway to increase the survival of these stem cells is very exciting,” says lead study author Theresa T. Lu, MD, PhD, an associate scientist in the Autoimmunity and Inflammation Program at HSS. “By uncovering these mechanisms and targeting them with treatments, perhaps one day we can better treat the disease."
