Cysteamine cystinosis mechanism
WebDisclosed herein are methods and compositions for modulating MFSD12 expression and activity to treat diseases such as lysosomal storage diseases, including cystinosis. Also disclosed are methods of altering skin pigmentation and methods of screening for MFSD12 modulation agents. WebCysteamine has an unpleasant sulfur odour, but the manufacturers of the cream claim to have reduced this by new technology. Theories how it reduces skin pigment include: Inhibition of tyrosinase and peroxidase Scavenging of dopaquinone Chelation of iron and copper ions Increasing intracellular glutathione.
