Researchers at the Walter and Eliza Hall Institute of Medical Research (WEHI) in Melbourne have discovered new cells that drive the aging process in the thymus that could unlock a way to restore function and prevent immunity from waning as we age. The thymus is the first organ in the body to shrink as people age. As this happens, the T-cell growth areas in the thymus are replaced with fatty tissue, diminishing T-cell production and contributing to a weakened immune system.
It was believed that they did not exist, but they are a reality. Scientists at the Francis Crick Institute in London have discovered stem cells in the thymus for the first time. The last organ to have its role described in humans still has properties that researchers could explore to prevent the decline of the immune system throughout life.
In the February 28, 2022, issue of the Journal of Experimental Medicine, researchers from Washington University in St. Louis have demonstrated that in a mouse model, there is a causal link between murine roseolovirus and autoimmune gastritis.
SEATTLE – As it enters its third year, the Human Cell Atlas project has mapped 100 million of 100 billion cells, and by comparing gene expression profiles of normal and aberrant cells and building networks of cellular interactions, is leading to breakthroughs in understanding of disease at a molecular level.
