Research Abstract |
To investigate role of sphingolipid in vivo, we generated conditional LCB2 gene-targeted mice. 1. Skin specific sphingolipid deficient mice Skin contain abundant sphingolipids different from other organs. The sphingolipids may play important roles for maintenance of barrier function. Therefore we generated skin specific sphingolipid deficient mice. These mice die 3 weeks after birth probably due to impaired barrier function. 2. T cell specific sphingolipid deficient mice Sphlingolipid deficient T cells poorly undergo cell maturation in thymus. This result implicate that sphlingolipid play important role for T cell selection in thymus.
