A new theoretical model helps explain how epigenetic memories, encoded in chemical modifications of chromatin, are passed from generation to generation. Within each cell’s nucleus, MIT researchers suggest, the 3D folding patterns of its genome determines which parts of the genome will be marked by these chemical modifications.
/PRNewswire/ -- Severe COVID-19 triggers changes that affect gene expression in immune system stem cells, causing long-lasting alterations in the body's immune...
A study from Weill Cornell Medicine and The Jackson Laboratory has described the epigenetic mark SARS-CoV-2 left on immune system stem cells in the most severe cases of COVID-19 early in the pandemic, before the development of vaccines.
A new study may provide a partial explanation for the long-term immunologic phenomena associated with COVID-19.
