• Background Sensitivity: mutants on a 129P2/Ola and 129S/SvEv background do not develop glomerulonephritis or autoantibodies as observed in mutants on a 129P2/Ola, 129S/SvEv, and C57BL/6 background

|
• 15% die at 4 - 6 months of age
|
|
• mutants develop high titers of anti-nuclear antibodies
|
|
• Background Sensitivity: severe proliferative crescentic glomerulonephritis evident in 27% mice with electron-dense immune deposits localized in the subendothelial and subepithelial areas
• Background Sensitivity: striking feature is presence of multiple apoptotic bodies in diseased glomeruli
|
|
• animals challenged with virulent pneumococci develop bacteremia and pneumonia after passive immunization with human IgG1 or human IgG2 unlike wild-type mice that are protected after immunization
|
|
• among mutants without glomerulonephritis, significantly greater numbers of glomerular apoptotic bodies are seen than in controls

|
• 9 of 10 mice exhibit stimuli evoked epileptiform activity, including all-or-none polyphasic events of variable form and latency lasting 150-400 ms that are associated with bursts of action potentials, unlike similarly treated wild-type mice
• 17 of 23 cortical layer V slices exhibit spontaneous epileptiform events with polyphasic morphology and duration similarly to the evoked epileptiform potentials unlike wild-type slices
• epileptiform activity is widespread in the cortex
• however, epileptiform activity is blocked by stimuli 2 or more times threshold
|
|
• mice exhibit spontaneous atypical absence seizures consisting of behavioral arrest with bihemispheric irregular electroencephalogram spike and slow wave activity lasting from 5 to 60 s unlike wild-type mice
• however, treatment with ethosuximide shortens seizure duration
|
|
• layer V pyramidal neurons exhibit a greater number of presynaptic excitatory synapses in different layers of the cortex compared with wild-type mice without increased strength of connectivity
|
|
• axonal bouton density is increased in pyramidal neurons compared to in wild-type cells
• the ratio of small to big boutons is increased compared to in wild-type mice
|
|
• whole cell recordings reveal spontaneous prolonged bursts of polysynaptic excitatory postsynaptic currents (EPSCs) unlike in wild-type cells
• EPSC maps are larger with a larger hot spot ratio than in wild-type mice
• however, EPSC amplitude is normal
|
|
• in the presence of tetrodotoxin, the frequency of spontaneous EPSCs in layer V pyramidal cells is higher than in wild-type mice
|
|
• whole cell recordings reveal spontaneous prolonged bursts of polysynaptic inhibitory postsynaptic currents (IPSCs) unlike in wild-type cells
• however, spontaneous IPSCs and miniature IPSCs frequencies are normal
|
|
• in the presence of tetrodotoxin, the frequency of miniature excitatory postsynaptic currents in layer V pyramidal cells is higher than in wild-type mice
|
