T cells, a type of immune cell, can impede the development and progression of multiple sclerosis in mice, according to a paper to be published in the September 2006 issue of Nature Immunology.
Many different types of T cells exist, each expressing a unique T cell receptor that helps the cell sense and react appropriately to its environment. J. Ludovic Croxford and colleagues show that a specific subset of T cells slows the onset and decreases the severity of a mouse version of human multiple sclerosis. The disease is worsened in the absence of these T cells, which block autoimmunity at least in part by triggering other immune cells to release chemical mediators that dampen the inflammatory response. Whether these T cells are involved in human autoimmune disease, and whether they can be harnessed for therapeutic intervention, remains to be determined.
