Post-ischemic inflammation is re-appraised as an important player in the progression of ischemic stroke. Activation of inflammatory cells via Toll-like receptor 2 (TLR2) and TLR4 is caused by several damage-associated molecular patterns (DAMPs), including high mobility group box-1 (HMGB-1) and heat shock proteins. We have recently found that peroxiredoxin (Prx) is one of the strong DAMPs and activates infiltrating macrophages in brain ischemia. We have also found that interleukin-23 (IL-23) from the activated macrophages stimulates γδT cells which release IL-17, thereby causing the delayed expansion of infarct lesions. Further investigation of the innate immune response would lead to development of novel stroke treatment with a broad therapeutic time window.
