Publication highlights


  • Discovery that the significant CNS tissue hypoxia resulting neuroinflammation is due to reduced blood flow.  The hypoxia can be sufficiently severe to impair mitochondrial function, which, in turn, prevents neurological function resulting in disability.  Also the finding that restoring blood flow using nimodipine restores spinal oxygenation and can rapidly reduce disability.  Further, that nimodipine therapy also reduces demyelination in both EAE, and a model of the early MS lesion (Desai et al, Ann. Neurol., 2020).

  • Finding that neuroinflammatory lesions can be severely hypoxic so that normal function is prevented, causing symptoms and demyelination.  Also that oxygen therapy can alleviate the symptoms (Davies et al., Ann. Neurol., 2013; Desai et al, Ann. Neurol., 2016 (Awarded the Multiple Sclerosis Research Prize for 2017)). 

  • Discovery in a model of diabetes that High Dietary Fat Consumption Disrupts Axonal Mitochondrial Function (Sajic et al., 2019, submitted).

  • Introduction of a method to protect brain function during resuscitation after haemorrhagic shock (Ida et al., Brit. J. Anaesth., 2018).

  • Finding that the drug safinamide has strong neuroprotective effects in neuroinflammatory models of MS (Morsali et al., Brain, 2013) and Parkinson’s disease (Sadeghian et al., Neuropath. Appl. Neurobiol., 2016).

  • Neuroprotection achieved in a stroke model by blockade of the sodium calcium exchanger (Bei & Smith, Neuropharmacol., 2012).

  • The discovery that sodium channel blocking agents are very effective neuroprotective agents in a range of neuroinflammatory lesions (Kapoor et al., Ann. Neurol., 2003; Bechtold et al., Ann. Neurol., 2004; Bechtold and Smith 2005; Bechtold et al., J. Neurol. Sci., 2005; Bechtold et al., J. Neurol., 2006; Morsali et al., Brain, 2013).

  • The discovery that the inflammatory mediator nitric oxide can both block axonal conduction (Redford et al., Brain, 1997) and cause degeneration (Smith et al., Ann. Neurol., 2001), and that sodium channel blocking agents can provide protection (Kapoor et al., Ann. Neurol., 2003).

  • Introduction of the first experimental model of the primary, or Pattern III, MS lesion (Felts et al., Brain, 2005; Marik et al., Brain, 2007; Sharma et al., Acta Neuropath., 2010).
