The cause of scleroderma is generally unknown, however areas being investigated include autoimmunity, environmental exposures, genetics, and infections. Many researchers feel that several factors work together to induce scleroderma, such as a genetic inclination along with exposure to a toxin or infection which triggers the illness. (Also see What is Scleroderma?, Types of Scleroderma, and Systemic Sclerosis)
Scleroderma is not believed to be contagious; you cannot get it by hugging or kissing someone or other intimate contact. There is an increased incidence of certain types other autoimmune diseases and cancer among scleroderma patients. (Also see Associated Conditions and Cancer and Scleroderma)
Noninvasive measurement of skin autofluorescence is increased in patients with systemic sclerosis: an indicator of increased advanced glycation endproducts? Autofluorescence is increased in patients with dcSSc compared to primary RP and to healthy controls. This suggests increased oxidative stress and the potential for autofluorescence as a biomarker.

Researchers implicate well-known protein in fibrosis. We now know that TLR4 plays a role in scleroderma, but much research remains to be done to develop safe and effective drugs to inhibit this pathway. EurekAlert, 11/20/12.
