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).

Brazilian researchers identify new way to stop excessive inflammation in COVID-19

Researchers at the University of São Paulo (USP) in Brazil have identified a new class of molecules capable of stopping the excessive inflammation typical of the severe form of COVID-19 without impairing the immune response to SARS-CoV-2, the virus that causes the disease.
