For many years, researchers have suspected that bacteria, viruses and other micro-organisms play an important role in the development of autoimmune conditions such as type 1 diabetes. This “hygiene hypothesis” postulates that our decreasing exposure to a lower amount of bugs and germs may leave some people more susceptible to autoimmune attacks.

A team of researchers from Yale University in the US have leant further support to this hypothesis by demonstrating that a certain strain of research mice were far more likely to develop type 1 diabetes when raised in a special germ-free environment as opposed to normal laboratory conditions.

A recent study shows that a new type of stem cell transplantation may help people with type 1 diabetes become insulin free and increase C-peptide levels.

Researchers have used a transplant of a patient’s own treated blood cells to increase and preserve beta cell function in young people recently diagnosed with type 1 diabetes.

The research team, from the US and Brazil, hoped that if they intervened early enough they could wipe out and then rebuild the body’s immune system by using stem cells, preserving a reservoir of beta cells and allowing them to regenerate.

Scientists believe they may have found a preventative therapy for type 1 diabetes that makes the body tolerate the insulin-producing cells that would normally be attacked and destroyed at disease onset.

PhD student Eliana Mariño and Dr Shane Grey, from the Garvan Institute of Medical Research in Sydney, have demonstrated how a particular molecule may be used to prevent type 1 diabetes in the future. Their findings are published online in the international journal Diabetes.

JDRF’s Research Development Manager said this research, part funded by JDRF, is significant. “These results are impressive and they represent a promising step towards a vaccine for type 1 diabetes.”
