Rosen/AAAS
B and T lymphocytes are either retained in lymph nodes in order to contact antigens and antigen-presenting cells or sent back out into the bloodstream for circulation. Circulating lymphocytes may enter tissues, where they mediate protective activities or cause tissue damage. Most immunosuppressive drugs work by inhibiting lymphocyte function: they either kill the cells directly, inhibit their production, or block signals downstream of antigen recognition. But FTY720 works in a novel manner.
Rosen's group found that a phosphate ester metabolite of FTY720 mimics the natural lipid...
