Scientists at The Scripps Research Institute have made a breakthrough in understanding a class of cells that help wounds in skin and other epithelial tissues heal, uncovering a molecular mechanism that pushes the body into wound-repair mode. The findings, which appear in an advance, online version of the Immunity on August 16, 2012, focus on cells known as ?d (gamma delta) T cells. The new study demonstrates a skin-cell receptor hooks up with a receptor on ?d T-cells to stimulate wound healing.
