Apoptosis in human autoimmune diseases.

ABSTRACT

The description of apoptosis or programmed cell death nearly thirty years ago did not initially stimulate a great deal of interest. However, the ways cells die is clearly an essential part of biological homeostasis and well worth of study in its own right as the enormous literature on the subject in the past 15 years confirms. In the past decade new avenues of apoptosis research have opened up as the relationship between this form of cell death and autoimmune disease has come under increasing scrutiny. Although most research to date has been in animal study models, there are a variety of studies which have begun to explore links between apoptosis and a wider range of human autoimmune conditions. In this review we analyse briefly the background to what is known about apoptosis and focus on the increasing likelihood that abnormalities in apoptosis are contributory factors in the development of human autoimmunity.
