Epigenetic alterations may play an important role in autism

Scientists at the University of Massachusetts Medical School are the first to map epigenetic changes in neurons from the brains of individuals with autism, providing empirical evidence that epigenetic alterations-changes in gene expression caused by mechanisms other than changes in the underlying DNA sequence-may play an important role in the disease.

Connexin 36 protects mouse pancreatic beta-cells against immune molecules

Type 1 diabetes is a lifelong disease characterized by high levels of sugar (glucose) in the blood. It is caused by the patient's immune system attacking and destroying the cells in their pancreas that produce the hormone insulin, which regulates blood glucose levels. Surprisingly, little is known about the mechanisms regulating the sensitivity and resistance of these cells, which are known as beta-cells, to immune system attack.
