The transition from an egg to a developing embryo is one of life’s most remarkable transformations. Now Whitehead Institute researchers have used fruit flies to decipher how one aspect—control of the translation of messenger RNAs (mRNAs) into proteins—shifts as the egg becomes an the embryo.  This type of switch could tell scientists more about how human cells work and embryos develop.

Using red blood cells modified to carry disease-specific antigens, a team of scientists from Whitehead Institute and Boston Children’s Hospital have prevented and alleviated two autoimmune diseases—multiple sclerosis (MS) and type 1 diabetes—in early stage mouse models.  This research is an exciting step toward therapeutics for autoimmune diseases, which affect an estimated 23 million Americans.
