A leukemia drug kills cancerous T-cells while sparing normal immunity
Leukemic cutaneous T-cell lymphoma (L-CTCL) is a leukemia arising from T-cells, a type of white blood cell. This cancer can involve the skin and other organs, and patients often die within three years.

Previously unknown cell interaction is key in immune system attacks
Most of the time, the immune system is the body's protector, warding off invading viruses and bacteria before they can lead to infection and disease. But in autoimmune diseases, the immune system does an about face, turning ...

T cell
T cells belong to a group of white blood cells known as lymphocytes, and play a central role in cell-mediated immunity. They can be distinguished from other lymphocyte types, such as B cells and natural killer cells by the presence of a special receptor on their cell surface called T cell receptors (TCR). The abbreviation T, in T cell, stands for thymus, since this is the principal organ responsible for the T cell's maturation. Several different subsets of T cells have been discovered, each with a distinct function.
