UTI in mice

Readout: behavioral and structural brain dysfunction

Mice with UTI demonstrated impairments of the frontal cortex and hippocampus, which were reversed following treatment with systemic anti-IL-6 antibody

2014

60 min bilateral ischemia reperfusion injury-induced AKI

Study endpoint/s: 2 and 24 h

Readout: cDNA based microarray

Mice with AKI exhibited upregulated mRNA levels of genes involved in inflammation

Bilateral renal ischemia reperfusion injury in rats

Readout: TLR-4 expression

↑ TLR-4 expression within hippocampus and striatum

60 min bilateral ischemia reperfusion injury-induced AKI

Study endpoint: 24 h

Readout: Histology

↑ Neuronal pyknosis and microgliosis

↑ Keratinocyte-derived chemoattractant and G-CSF in the cerebral cortex and hippocampus

↑ Expression of glial fibrillary

acidic protein in astrocytes in the cortex and corpus callosum

Adachi et al.

Bilateral rat renal artery occlusion. Endpoint: 48 h

Readout: motor activity and brain monoamine turnover

↓ Turnover of DA in the striatum, mesencephalon and hypothalamus

Impaired motor activity
