A new study underscores inter-relationships b/w a number of disorders including PD with a type of cancer " for nearly 50 years, doctors have recognized that Parkinson's disease patients are more likely to develop melanoma than the general population. Now, scientists report a molecular link between the two diseases in the form of protein aggregates known as amyloids. While intense research has focused on the effects of α-synuclein in the brain, much less is known about its presence or activities in other tissues. However, scientists have evidence that the amyloid-forming protein is expressed more in melanoma cells than in healthy skin. Furthermore, higher levels of α-synuclein in melanocytes (the skin cells that give rise to melanoma) correlate with reduced pigment, or melanin, production. Melanin protects skin from damage by the sun's ultraviolet rays. " Study Excerpt .
