Keloid disease predominantly affects African Americans, Hispanics and some Asians. Keloid disease is characterized by an overgrowth of an area of the skin following some injury to that same skin area. It is unknown why this occurs. However, we believe that differences in Vitamin D along with dysfunction in certain immune system receptors can lead to keloid disease. To further understand this process we intend to study the cells (fibroblasts) in the skin that are affected by Vitamin D and examine the specific immune proteins.
