| 1 | Pertussis toxin–induced inflammatory response exacerbates intracerebral haemorrhage and ischaemic stroke in mice显示文摘Background Stroke is a devastating disease,including intracerebral haemorrhage(ICH)and ischaemic stroke.Emerging evidences indicate that systemic inflammatory cascades after stroke contribute to brain damage.However,the direct effects and features of systemic inflammation on brain injury,especially comparing between ischaemic and haemorrhagic stroke,are still obscure.Methods Pertussis toxin(PT)was used to build a pro-inflammatory milieu after ICH and ischaemic stroke in mouse model.The neurodeficits,stroke lesion,immune response and blood–brain barrier(BBB)destruction were assessed.Results In ICH mouse model,PT-induced systemic inflammation exacerbated neurological deficits,and enlarged haemorrhage lesion and perihaematomal oedema.We also found promoted leucocyte infiltration and inflammatory cytokine release into the brain after PT treatment.Moreover,the integrity of the BBB was further disrupted after receiving PT.Furthermore,we demonstrated that PT enhanced brain inflammation and aggravated stroke severity in middle cerebral artery occlusion mouse model.Conclusions Our results suggest that PT increases inflammatory response that exacerbates brain injury after ICH or ischaemic stroke in mouse model. | Ming Zou Yan Feng Yuwhen Xiu Yan Li Ying Zhang Junwan Fan Haowen Li Jingli Cao Wenyan He Wei-Na Jin | 2022 | Stroke & Vascular Neurology2022，7，1： | 1 |
