Fonte: Babraham Institute Moving genes about could help cells to respond to change according to scientists. Changing the location of a gene within a cell alters its activity. Contrary to expectations, this latest study reveals that each gene doesn’t have an ideal location in the cell but are constantly moving. https://www.sciencedaily.com/releases/2017/07/170705133028.htm

Fonte: MedicaXpressWhen the immune system is imbalanced, either due to overly-active cells or cells that suppress its function, it causes a wide range of diseases, from psoriasis to cancer. By manipulating the function of certain immune cells, called T cells, researchers could help restore the system’s balance and create new treatments to target these diseases.https://medicalxpress.com/news/2017-08-reveals-reprogram-cells-immune.html
