SOCS1 reporter expression is increased during CD8+ CTL differentiation in NOD islets. (A) Pancreatic lymph nodes and islets were isolated 5 days after 8.3 splenocyte transfer, CFSE positive cells were isolated by cell sorting and CTL activity quantified in vitro. Data show mean + SEM from 3 independent experiments. **p < 0.01. (B) Representative plots of pancreatic lymph nodes (PLN) and islets isolated 5 days after 8.3/hCD4 splenocyte transfer showing expression of hCD4 and CFSE dilution. (C) Expression of hCD4 (mean fluorescence intensity, MFI) on CD8+CFSE+ T cells for each cell division was calculated using CFSE dilution profiles. Data show mean ± SEM for n = 6 mice from 3 independent experiments. **p < 0.01, one-way ANOVA comparing division 1 and division 7.
