What had been learned of gamma-delta T cells in the nearly two decades since their initial discovery was that they arise early in fetal development in the thymus.
Unlike other T cells in the body, which display a wide diversity of receptors that recognize a wide diversity of antigens - the molecular components of various pathogenic invaders - the gamma-delta T cells in the skin seem to have little, if any, diversity and display a uniform receptor and recognize only a single antigen.
The new study showed that when skin is cut or damaged, keratinocytes, a type of epithelial cell common in the epidermis, release the antigen that is recognized by the gamma-delta T cells, which then become activated.
