• Biography/ Background

  Dr Alsharifi studied Biomedical Science at Monash University. After graduating with First Class Honours, he moved to the Australian National University to take up a PhD scholarship at The John Curtin School of Medical Research. During his PhD, he investigated with Prof Arno Müllbacher, Prof Robert Blanden, and Dr Mario Lobigs the immunobiology of an alphavirus infection. During his early years in research he discovered a period of exhaustion in type-I interferon response following an acute viral infection, which may explain the clinically known observation that virus-infected patients are at increased risk to a more sever secondary viral and/or bacterial infection. Following the completion of his PhD studies, he investigated with Prof Müllbacher the possibility of using gamma-irradiated influenza virus as a universal flu vaccine. In 2008, he was awarded the Hanson Fellowship to continue his research into the universal Flu vaccine and also to investigate the possibility of producing other vaccines using similar technique to that used for influenza. His flu vaccine research has been featured in the Catalyst program on ABC (), and in many newspaper articles such as () and  ().

  Concepts Related to the Development of Gamma-Irradiated Vaccines:

  Gamma irradiation has become a “gold standard” for inactivating highly dangerous pathogens such as the Ebola virus. However, despite our advance knowledge, more investigations are required for a much better understanding of the conditions and parameters required to achieve sterility of infectious materials in accordance with the international benchmark, the “Sterility Assurance Level”. This project is expected to systematically investigate the underlying parameters influencing the sterility of γ-irradiated preparations. It will allow us to quantify any structural damage induced by γ-irradiation in viruses and bacteria and also to classify viruses and bacteria based on their suitability as γ-irradiated vaccine candidates.

   

  Cross-Protective Influenza Vaccine:

  Protection against re-infection with homotypic influenza virus is mediated primarily by neutralizing antibodies but recovery from newly arisen influenza virus infections requires cytotoxic CD8+ T (Tc) cells. While neutralizing antibodies target mainly the viral surface glycoproteins (HA and NA), which are subject to frequent antigenic variation, influenza-immune Tc cells target the more conserved proteins, such as the viral nucleoprotein (NP) and matrix protein. Accordingly, any universal influenza vaccine should have the capability of inducing cross-protective Tc cell responses. We have developed cross-protective influenza A virus vaccine and we aim to investigate CTL responses in terms of activation, recruitments into the lung and long term tissue persistence.

    

  Exhaustion of IFN-I Response and the Susceptibility to Secondary Infections:

  We have previously reported that type I interferon (IFN-I) response mediates systemic, partial lymphocyte activation which is evident by elevated expression of CD69 and CD86. Interestingly, we have found a period of exhausted IFN-I responses as a result of primary viral infections, which was associated with enhanced susceptibility to a secondary infection with an unrelated virus. Our aim is to investigate the underlying factors responsible for the deficiency in IFN-I responses following acute viral infections, and to address some therapeutic approaches to alleviate the period of the enhanced susceptibility.
