Do Germs Trigger Type 1 Diabetes?
I always have this nagging feeling that I forgot to wash my hands or something when Arden was a baby. I know how ridicules it is to wonder but it's difficult at times not to think, "what if I could have done something differently...". Anyway, I thought this was an interesting article that you may like to see. Excerpts below with links to the entire research article if you're interested in reading more.

Germs could play a role in the development of type 1 diabetes by triggering the body's immune system to destroy the cells that produce insulin, new research suggests.
“Killer T-cells sense their environment using cell surface receptors that act like highly sensitive fingertips, scanning for germs.
”However, sometimes these sensors recognise the wrong target, and the killer T-cells attack our own tissue. We, and others, have shown this is what happens during type 1 diabetes when killer T-cells target and destroy beta cells.”
Scientists have previously shown that killer T-cells, a type of white blood cell that normally protects us from germs, play a major part in type 1 diabetes by destroying insulin producing cells, known as beta cells.
Now, using Diamond Light Source, the UK's synchrotron science facility to shine intense super powerful X-rays into samples, a team from Cardiff University's Systems Immunity Research Institute found the same killer T-cells that cause type 1 diabetes are strongly activated by some bacteria.
The team hope this research will lead to new ways to diagnose, prevent or even halt type 1 diabetes.
