DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Small protein prevents immune system from destroying pancreatic cells in type 1 diabetes-prone mice

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