Islet-specific CTL cloned from a type 1 diabetes patient cause beta-cell destruction after engraftment into HLA-A2 transgenic NOD/scid/IL2RG null mice.

Autor: Wendy W J Unger, Todd Pearson, Joana R F Abreu, Sandra Laban, Arno R van der Slik, Sacha Mulder-van der Kracht, Michel G D Kester, Dave V Serreze, Leonard D Shultz, Marieke Griffioen, Jan Wouter Drijfhout, Dale L Greiner, Bart O Roep

Publikováno v: PLoS ONE, Vol 7, Iss 11, p e49213 (2012)

Despite increasing evidence that autoreactive CD8 T-cells are involved in both the initiation of type 1 diabetes (T1D) and the destruction of beta-cells, direct evidence for their destructive role in-vivo is lacking. To address a destructive role for
