Abstract
Apoptotic and inflammatory events are usually implicated in brain Ischemia Reperfusion (IR) and are therefore considered as potential targets for treatment. Thalidomide (TH) has a well-documented anti-inflammatory effect by inhibiting TNF-a which is also a major player during the (IR) mechanistic work-up. Therefore, the current study aimed at investigating the possible neuroprotective effects of intra-hippocampally injected (TH) in an (IR) model in rats induced by bilateral carotid occlusion for 45 min, followed by 24 h reperfusion. (IR) resulted in significant memory impairment paralleled with a clear motor incoordination as well as an enhanced locomotor activity and an apparent histo-pathological damage. The latter effects were dwindled by the unilateral intrahippocampal injection of (TH). Moreover, IR induced an upsurge in TNF-a and its downstream mediator nuclear factor (NF)-kB, brain-derived neurotropic factor (BDNF), caspase-3, and iNOS; which were all mitigated by intra-hippocampally injected (TH). On the other hand the reductions in IL-10 and nNOS levels induced by IR were ameliorated by (TH) treatment. Henceforth, the current study results suggest a possible protective role of the centrally administered (TH) in IR injury with a conceivable connotation of both apoptotic and inflammatory pathways.
