immune system
• decreased T cell proliferation when stimulated by CD3 cross linking but not when stimulated by PMA or ionomycin
• swelling of ankles and forepaws induced by injection of serum from mice transgenic for Tg(TcraR28,TcrbR28)KRNDim is significantly reduced compared to controls

behavior/neurological
N
• no abnormalities in motor activity or anxiety like behavior are detected
• when using a modest training protocol mice display significantly less freezing upon reexposure 24 hours later to the context or cue but no defect is detected when reexposure occurs 1 hour after training suggesting an impairment in long term memory
• when using a modest training protocol mice display significantly less freezing upon reexposure 24 hours later to the context
• however, no defect is detected when a more intense training protocol is used or when testing is done 1 hour after training
• when using a modest training protocol mice display significantly less freezing upon reexposure 24 hours later to the cue
• however, no defect is detected when a more intense training protocol is used or when testing is done 1 hour after training
• in a probe trial of a Morris water maze 7 days after training mice display fewer platform crossings but spend a similar amount of time in the target quadrant compared to controls
• 24 hours after training latency to enter the dark side (where a shock was given during training) is reduced compared to controls

nervous system
• cell body spiking following the first train of theta burst is significantly reduced compared to controls
• decrease in theta burst stimulated long term potentiation, especially in the first hour post induction
• however, long term potentiation in response to 2 high frequency stimulations is similar to controls

hematopoietic system
• decreased T cell proliferation when stimulated by CD3 cross linking but not when stimulated by PMA or ionomycin

skeleton
• swelling of ankles and forepaws induced by injection of serum from mice transgenic for Tg(TcraR28,TcrbR28)KRNDim is significantly reduced compared to controls

cellular
• decreased T cell proliferation when stimulated by CD3 cross linking but not when stimulated by PMA or ionomycin
