Inflammatory markers in the hippocampus after audiogenic kindling
2020
Abstract Here, we investigated the participation of pro and anti-inflammatory cytokines in the spread of repeated audiogenic seizures from brainstem auditory structures to limbic areas, including the hippocampus. We used Wistar Audiogenic Rats (WARs) and Wistars submitted to the audiogenic kindling protocol with a loud broad-band noise. We measured pro and anti-inflammatory cytokines and nitrate levels in the hippocampus of stimulated animals. Our results show that all WARs developed audiogenic seizures that evolved to limbic seizures whereas seizure-resistant controls did not present any seizures. However, regardless of seizure severity, we did not observe differences in the pro inflammatory cytokines IL-1β, IL-6, TNF-α and IFN-α or in the anti-inflammatory IL-10 in the hippocampi of audiogenic and resistant animals. We also did not find any differences in nitrate content. Our data indicate that the spread of seizures during the audiogenic kindling is not dependent on hippocampal release of cytokines or oxidative stress, but the severity of brainstem seizures will be higher in animals with higher levels of cytokines and the oxidative stress marker, nitrate.
