immune system
|
• increased CD4+ T cell number in spleen at 12-14 months of age
|
|
• increased CD8+ T cell number in spleen at 12-14 months of age
|
|
• decreased number of Foxp3+CD4+ Treg cells in spleen at 12-14 months of age
|
|
• increased plasma IgG3 levels at 12 months of age, consistent with increased T cell-derived IL-17 levels
|
|
• at 12-14 months of age, mice exhibit an increase in CD44+ active T cells and a decrease in CD62L+ naive T cells, suggesting that T cells are hyperactivated

|
• increased plasma MCP-1 levels at 12-14 months of age
|
|
• increased plasma interferon-gamma levels at 12-14 months of age
• plasma interferon-gamma levels are somewhat reduced at 24 h of rapamycin treatment and return to basal (pre-treatment) levels after 2 weeks of rapamycin treatment, similar to what is observed in wild-type controls
