| abstractText | Previous studies have provided evidence that a quantitative trait locus (QTL) on the distal part of chromosome 18 (chr18) is a major determinant of vulnerability to hippocampal neurodegeneration following kainic acid (KA)-induced seizures in inbred mouse strains. We assessed excitotoxic vulnerability in two congenic, 'genome tagged' mouse strains carrying segments of either distal or proximal/medial chr18 from vulnerable DBA/2J mice on a resistant C57BL/6 background. Systemic KA injections triggered brain-wide neurodegeneration in the distal chr18 congenic strain, and specifically in the hilus of the dentate gyrus, but not in CA3. In contrast, the proximal/medial chr18 congenic strain exhibited enhanced degeneration in CA1 and CA3, but little neurodegeneration elsewhere. Both strains exhibited low levels of QUIN-induced striatal neurodegeneration comparable to what is seen in C57BL/6 mice. These results suggest that gene(s) on distal chr18 are important determinants of vulnerability to KA-induced hippocampal neurodegeneration, but not QUIN-induced striatal neurodegeneration. |
