摘要

Diabetes has been termed the epidemic of the 21st century and over the past 50 years in Western societies has been doubling in incidence every 15 years. It exacts a huge socioeconomic toll because of its devastating microvascular and macrovascular complications and the need of patients to maintain a lifetime daily therapeutic regimen. The childhood-onset form of diabetes, which accounts for 10% of all cases in humans [autoimmune or type 1 diabetes (IDDM)], is the product of a T lymphocyte-dependent autoimmune process that specifically destroys the insulin-secreting β cells of the pancreas without affecting contiguous endocrine cells or the surrounding exocrine tissue. Such tissue and cell specificity might logically be the product of an autoimmune reactivity directed at β-cell-specific molecular targets mediated by direct cellular contact between the target β cell and effector cytotoxic T lymphocytes.
