tg2

• Allelic Composition: Tg(Tnf)6074Gkl/0
• Genetic Background: involves: C57BL/6 * CBA

nervous system

abnormal astrocyte morphology ( J:106592 )

• at 8-10 weeks of age some astroglial scarring

abnormal microglial cell morphology ( J:106592 )

• at 1 week of age there is widespread microglial activation

• at 8-10 weeks plaque edge cells contain myelin degradation products

abnormal meninges morphology ( J:106592 )

• minimal blood-brain barrier damage and immune infiltration can be observed at the meninges at 1 week of age

• at 4 weeks of age pronounced inflammation at the brain meninges

axon degeneration ( J:106592 )

• at 8-10 weeks of age moderate axonal damage is evident within plaques

abnormal nervous system physiology ( J:106592 )

• at 1 week of age TUNEL+ cells characteristic of apoptosis are found in the corpus callosum

impaired blood-brain barrier function ( J:106592 )

• at 8-10 weeks of age signs of BBB leakage

abnormal oligodendrocyte apoptosis ( J:106592 )

• oligodendrocyte apoptosis starting at 1 week of age

brain inflammation ( J:106592 )
