Popis: Type 1 diabetes (T1D) is a multifactorial disease characterized by the infiltration and subsequent destruction of the pancreatic insulin-producing beta cells by autoreactive T cells. CD8(+) T cells play an essential role in this beta cell destruction. However, little is known about the target antigens of CD8(+) T cells in human T1D patients. The aim of this study was to assess whether an epitope derived from the islet-specific glucose-6-phosphatase catalytic subunit-related protein (IGRP), IGRP(265-273,) which has recently been identified as a target in non-obese diabetic (NOD) mice and is fully homologous to the human epitope, is a target of human diabetogenic CD8(+) T cells. We isolated a human CD8 T cell clone against this epitope, which confirms that this IGRP epitope is shared across species.
