SARS-CoV-2-induced dead cell fragments drive viral uptake and inflammation. This project will apply advanced cell biology and imaging techniques to investigate how macrophages, which lacks a canonical receptor for viral entry, become infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and elicit inflammatory responses. Its insights into a novel pathway of viral entry is expected to advance our understanding of host-pathogen interaction.

This project will apply advanced cell biology and imaging techniques to investigate how macrophages, which lacks a canonical receptor for viral entry, become infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and elicit inflammatory responses. Its insights into a novel pathway of viral entry is expected to advance our understanding of host-pathogen interaction. The project is intended to uncover the role of SARS-CoV-2-induced dead cell fragmentation in promoting viral uptake and inflammation. Its findings should provide significant scientific, health and economic benefits by informing new research directions on infection and innate immunity as well as future therapeutic designs for infection treatment.Read moreRead less

The placenta is an essential organ required for reproduction in placental species. This project aims to elucidate the fundamental biology of SPINT1 in placental development. It will generate new knowledge about whether the spatial and temporal expression of SPINT1 is conserved across several species; cow, sheep, lizard, mouse and human. It will also define the molecular mechanisms by which SPINT1 directs formation, maturation and expansion of the placental exchange interface which is critical for offspring survival.
The project will increase understanding of placental development, enhance collaboration and research knowhow, and promote future applied projects in all species that reproduce via placental support.Read moreRead less

Exercise boosts the generation of new nerve cells from adult neural stem cells in the part of the brain responsible for learning and memory, the hippocampus. This project aims to investigate the mechanisms behind this effect, in particular, how blood cells known as platelets mediate this process. The expected outcomes include the discovery of new communication pathways between platelets and the brain following exercise and will determine the importance of these blood cells in mediating brain function. This will help to explain how exercise affects the brain and may benefit Australian society through the implementation of new methods to support learning and memory in schools and workplaces, thereby enhancing performance and productivity.Read moreRead less

Editing the genome of an organism in an efficient and safe fashion is critical for the livestock and biotechnology industries. While CRISPR-Cas9 has become the method of choice for genome editing, it is known to introduce unwanted "on-target" and "off-target" mutations, limiting its utility. To address this the CI team created a novel genome editing platform technology termed Crackling-CAST that is almost 100% accurate, while retaining the efficiency of the classical Cas9 system. This project will exemplify the capabilities of the novel gene targeting platform in cell types used by the biotechnology and livestock sectors, ensuring its global uptake by these industries and delivering significant economic benefits for Australia.
