|
behavior/neurological
|
• homozygotes display impaired contextual fear conditioning but normal auditory fear conditioning
|
|
• homozygotes display impaired hippocampus-dependent spatial memory in a Morris water maze with repeated trials (strong conditioning) but improved spatial memory with a single trial (weak conditioning)
|
nervous system
|
• a single tetanus induces a robust and sustained late LTP unlike in wild-type mice where a single tetanus induces early LTP
• after repeated tetanic stimulation (4 trains at 100 Hz) the duration of late LTP is reduced, returning to baseline within 3 hours

behavior/neurological
|
• mice have much less of an aversion to diets lacking an essential amino acid
• mice consume 7.7% less leucine-deficient chow after 1 hour compared to wild-type mice that consume 28.8% less
• mice consume 9.4% less leucine-deficient chow after 4 hours compared to wild-type mice that consume 34.1% less
• similar responses are observed in threonine-deficient diet

immune system
|
• splenic CD19+ dendritic cells treated with CTLA4-immunoglobulin do not produce IFNalpha, indicating a defect in response to CD80/86 (B7) ligation; production induced by TLR9 stimulation is equivalent to that in wild-type
|
|
• splenic CD19+ dendritic cells do not secrete IFNalpha upon CTLA4-Ig treatement
