A new study has shown that treating mice with type 1 diabetes with small proteins called MOTS-c prevented the immune system from destroying insulin-producing pancreatic cells, effectively preventing the onset of autoimmune disease. (1)

The professor of gerontology Changhan David Lee, co-author of the study, explained that these small proteins activate a “mimetic exercise “ they appear to play an important role in regulating the immune system.
