Latest Natural Killer T cell Stories

Mice that were fed diets high in fat and sugar developed immune system abnormalities in their livers, including reduced numbers of natural killer T (NKT) cells. These diet-related changes may contribute to obesity-related liver disease, according to a new study. The study is published in the October 2005 issue of Hepatology, the official journal of the American Association for the Study of Liver Diseases (AASLD). Published by John Wiley & Sons, Inc., Hepatology is available online via...

With the advent of nuclear-transfer cloning, it is now possible to produce mice from the nuclei of differentiated cells, such as peripheral blood lymphocytes and olfactory sensory neurons. However, unlike most other clones, those formed with the nuclei of differentiated cells were generated by a two-step nuclear-transfer procedure that might allow the donor genome further reprogramming. Thus, these findings do not settle the question of whether the egg cytoplasm can itself reprogram a fully...
