With this conclusion, it was revealed that genes that works to maintain pigmentation also serve to the immune system and any potential infections that could occur to attack the host. In my opinion, the future of this research finding could go in so many different directions, potentially the connection among the pigmentation and the immune system to discover what causes pigmentation diseases, where pigment is present in patches on the skin, to see what other research could be done to possibly reverse the process of gray hair. This kind of discovery could even explain extreme cases like albinism, no pigmentation in the skin at all, and if those people also have a poor immune system, as being another approach rather than looking at the melanocytes as the only possible explanation for the disease. This could also potentially explain further why younger people are starting to see gray hairs when their melanocyte stem cells should be working and functioning properly, then MITF could figure out the problem.
