New method isolates immune cells to study how they ward off oral diseases

Dental researchers have found a less invasive way to extract single rare immune cells from the mouth to study how the mouth’s natural defenses ward off infection and inflammation. By isolating some specialized immune cells (white blood cells known as "leukocytes") to study how they fight diseases in the mouth -- or reject foreign tissues, such as in failed organ transplants -- researchers hope to learn more about treating and preventing such health issues as oral cancers, cardiovascular disease, AIDS and other infectious diseases.
