The immune system protects us against billions of bacteria, viruses, and other parasites. Most of us never reflect upon the fact that while we are busy with our lives, our immune system is constantly on the alert inside our body, attacking harmful organisms at the first sign. It is very complex. It’s made up of several types of cells and proteins that are designed to perform various jobs.
Dr. Ciriaco Piccirillo, a researcher in the ‘Department of Microbiology and Immunology’ and the principal investigator, said that the CD4+Treg cells, the main regulators of the immune system, play a significant role in a large range of immune diseases. The gradual reduction in their regulating capacity seems to play a critical role in the onset of type 1diabetes.
