Assoc. Prof. David Harrich, Queensland Institute of Medical Research, Australia
Bio: David is a graduate of the University of California San Diego in biochemistry and cell biology (B.Sc) and of the University of California Los Angeles in Experimental Pathology focusing on HIV-1. His post-doctoral studies were at the University of Texas Southwestern (Dallas, Tx) were he was awarded an NIH Infection and Immunity Fellowship. He accepted a Lab Head position in the Sir Albert Sakzewski Virus Research Centre in Brisbane, Queensland Australia and then relocated to QIMR Berghofer Medical Research Institute in Brisbane in 2002. He was appointed a Group Leader in 2009. His interests include regulation of HIV-1 gene expression by Tat and TAR RNA, the role played by cellular factors in regulating retrovirus and paramyxovirus replication, and more recently on the development of antiviral agents derived from viral RNAs.
Title:
Harnessing defective interfering particles and lipid nanoparticles for effective delivery of an anti-dengue virus RNA therapy
Talk Description: Presently, no approved antiviral drug targets dengue virus (DENV) infection. Treatment mainly relies on supportive measures, while the efficacy of DENV vaccines varies based on factors like vaccine type, circulating DENV serotypes, and the vaccinated population. This research explores using defective interfering particles (DIPs) and lipid nanoparticles (LNPs) to deliver an anti-DENV defective interfering RNA, known as DI290.
Results showed that both DENV DIPs and DI290-loaded LNPs (LNP-290) effectively suppressed DENV infection in human primary monocyte-derived macrophages (MDMs), THP-1 macrophages, and human fibroblasts, which are cell types naturally targeted by DENV. In addition to inhibiting DENV, DENV DIPs and LNP-DI290 also inhibit zika virus (ZIKV), yellow fever virus (YFV), Japanese encephalitis virus (JEV), respiratory syncytial virus (RSV) and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in vitro. Furthermore, LNP-290 demonstrated approximately 98% inhibition of DENV-2 viral loads in IFNAR-deficient mice, which lack functional type I interferon (IFN) receptors, compared to control-treated IFNAR-deficient mice. DI290-mediated inhibition was also effective in IFN regulatory factor 3 and 7 double knockout mice, where viral titers in serum and spleen were undetectable, and no viral RNA was detected in spleen samples from treated mice.
Although DENV inhibits IFN responses, the data suggests that DI290 can activate IFN responses in DENV-2 infected IFNAR-deficient mice, resulting in complete suppression of DENV-2 replication. RNA-Seq data from LNP-290-treated C57BL/6J mice and IFNAR-deficient mice, and human primary MDMs treated with LNP-DI290 or DENV DIPs illustrated that DI290 treatment heightened IFN responses, particularly IFNγ, as well as IFNα/β and IFNλ. DI290 thus induces a broad range of IFN responses, with IFNγ and IFNλ providing antiviral activity when IFNα/β responses are absent.

Dr. Andrew Mooney, Conservation and Research Officer at Dublin Zoo
Bio: Andrew is the Conservation and Research Officer at Dublin Zoo, where he is responsible for the management and strategic development of all conservation and research activities supported by Dublin Zoo. Andrew did his undergraduate in Zoology at TCD, which was followed by a PhD in Zoology, also at TCD, under the supervision of Prof. Yvonne Buckley. He is currently the Vice Chair of the BIAZA Research Committee, and is a member of the IUCN Animal Biobanking for Conservation Specialist Group.
Title
Genetic Rescue - Realising the Conservation Potential of Biobanking
Talk Description: Recent technological advancements, in conjunction with global biobanking efforts, mean that a suite of genetic tools can now be deployed to restore genetic diversity, reverse global biodiversity loss and even result in species de-extinctions. Using examples from San Diego Zoo to Dublin Zoo, this seminar will explore the emerging science of genetic rescue, highlighting conservation successes to date, current obstacles facing conservation practitioners, and the future conservation potential of biobanking.

Title
Molecular aspects of defence against invasive aspergillosis
Abstract : The airborne opportunistic fungal pathogen Aspergillus fumigatus causes severe systemic infections in immunocompromised patients. Multiple mechanisms contribute to the host’s defence against and successful treatment of invasive aspergillosis. We are interested in understanding the molecular aspects of the invasive infection and how antifungal treatments help to eliminate this pathogen from the host.
