Exosomes are a class of extracellular vesicle, membrane-wrapped packages of molecules that carry a sizable fraction of the chemical communications that takes place between cells. The various types of extracellular vesicle are presently ordered in a taxonomy by their size rather than any more subtle combination of features. Those … Read more
Lowered Iron Levels in Hematopoietic Stem Cells Reverse Some Age-Related Dysfunction Researchers here report on a way to reverse some of the age-related dysfunction observed in the hematopoietic stem cell population resident in bone marrow. These cells are responsible for generating red blood cells and immune cells. Some fraction … Read more
Here, researchers investigate correlations between late life mortality and levels of specific proteins produced by senescent cells as a part of the senescence-associated secretory phenotype (SASP). While looking over the paper, it is worth bearing in mind that circulating levels of many of the molecules thought to be important … Read more
