Multiple myeloma is the second most common blood cancer in adults. It starts in the white blood cells that are responsible ...

Cells are enveloped by a lipid membrane that gives them structure and provides a barrier between the cell and its environment. However, evidence has recently emerged suggesting that these membranes do ...

As we age, our ability to maintain healthy blood and a strong immune system gradually declines, largely because hematopoietic ...

The regulatory division of the immune system is vital for its overall function. Immune T cells originate in the bone marrow and then travel to the thymus—a kind of biological police academy. 2 Here, ...

Cancer is often seen as a disease that arises from genetic mutations causing cells to divide uncontrollably and invade other parts of the body. But the spread of cells away from their origins is ...

The stress hormone cortisol can weaken the liver when excess is released over a short period of time.
