Effect of Inflammation on the Process of Stroke Rehabilitation and Poststroke Depression
Conclusions Stroke comprises ischemic stroke and ICH. The immuno-inflammatory process is involved in neural plasticity following events such as a hemorrhage or ischemic stroke. After ischemia, astrocytes, microglia, and MDMs play important roles during rehabilitation with the modulation of cytokines or chemokines, such as TNF-α and IL-1. Moreover, MiRNAs are also important posttranscriptional regulators in these glial mitochondrial responses to cerebral ischemia. ICH involves processes similar and different to those seen in ischemia, including neuronal injury, astrocytic and microglial/macrophage activation, and n...

Neuroprotection in acute stroke: targeting excitotoxicity, oxidative and nitrosative stress, and inflammation
Publication date: Available online 11 May 2016 Source:The Lancet Neurology Author(s): Ángel Chamorro, Ulrich Dirnagl, Xabier Urra, Anna M Planas Treatments for acute ischaemic stroke continue to evolve after the superior value of endovascular thrombectomy was confirmed over systemic thrombolysis. Unfortunately, numerous neuroprotective drugs have failed to show benefit in the treatment of acute ischaemic stroke, making the search for new treatments imperative. Increased awareness of the relevance of rigorous preclinical testing, and appropriate selection of study participants, might overcome the barriers to progress...

Hypothermia followed by rapid rewarming exacerbates ischemia-induced brain injury and augments inflammatory response in rats.
Abstract Hypothermia followed by slow rewarming is neuroprotective for ischemic stroke. However, slow rewarming causes patients' longer stay in intensive care unit and increases the risk of hypothermic complications. Hypothermia followed by rapid rewarming (HTRR) is more convenient; but it exacerbates intracranial hypertension for patients with massive hemispheric infarcts. The present study aims to investigate in detail how HTRR exacerbates ischemic brain injury and what are underlying mechanisms. Rats subjected to transient focal ischemia by middle cerebral artery occlusion were treated with normothermia or hypo...

Emerging experimental therapies for intracerebral hemorrhage: targeting mechanisms of secondary brain injury.
This article reviews the pathophysiology of secondary brain injury relevant to ICH, examines pertinent experimental models, and highlights emerging therapeutic strategies. Treatment paradigms discussed include thrombin inhibitors, deferoxamine, minocycline, statins, granulocyte-colony stimulating factors, and therapeutic hypothermia. Despite promising experimental and preliminary human data, further studies are warranted prior to effective clinical translation. PMID: 23634928 [PubMed - in process]
