Recognition of RNA fragments by TLR7 and TLR8 helps to initiate the innate immune response. This work redefines TLR7 and TLR8 sensing by introducing 2′-OMe guanosine as a natural immune checkpoint for their activation. @NatImmunol 🔗 go.nature.com/4azVWjp

@sciencescanner @3DiMMUNE We don't know yet. However it is conceivable that receptors such as TLR7/8 needed a built-in off-switch in their LRRs, and that it would have then evolved as a sensing mechanism when nucleic acids accumulate.

I am delighted to share our characterisation of natural antagonism of TLR7/8 in Nature Immunology. We propose a model where 2’O-Methyl RNA fragments keep TLR7/8 in check, preventing autoimmunity. > nature.com/articles/s4159…

How does your immune system tell pathogenic RNA from your own, even though they’re made of the same stuff? Our latest paper with @GantierLab shows some self RNA act as an off switch preventing autoimmunity in the absence of pathogens. 🧬🔬⭐ nature.com/articles/s4159…

@3DiMMUNE We propose it is the accumulation of agonistic fragments (short RNAs and nucleosides which work cooperatively) which outcompetes the basal natural antagonism.

@GantierLab How, then, are TLR7/8 activated if such antagonistic fragments are abundant?

Excited to share our latest work on how microRNA length variants can be leveraged as disease biomarkers. Congratulations to Alex McAllan for all her work on this! cell.com/molecular-ther…

We are thrilled to announce the official launch of the #RNAte Platform at @Hudson_Research, delivering huge advances in the development of #mRNA-based therapies. 🥳💪🏽 Read more about this revolutionary platform: bit.ly/3SEEl23 @VicGovAu @VicGov_DJSIR

We recently welcomed Deputy Premier & Minister for Medical Research, The Hon @BenCarrollMP to Hudson Institute! 🙌 Minister Carroll went behind the scenes with some of our researchers, including our CEO & Director Prof Elizabeth Hartland, to learn more about our research.🔬

@Hudson_Research @CiiiD_Hudson Thrilled to be joining longtime friends and colleagues @CiiiD_Hudson including those I could find on twitter @ProfHartland @FerreroMicro @Tate_Lab @GantierLab @pjhpauljh @Forster_Lab @PhilBardin

@pjhpauljh Congratulations Dom!!!

Congrats Dom Hugely addressed

@Labo_Pepin Congratulations Genevieve and the entire team!!!

Exciting data to build our research program on thromboinflammation! So proud of this first research paper! Thanks to the many students and collaborators who contribute to this story! life-science-alliance.org/content/7/2/e2…

Our latest work, out today in @PLOSBiology suggests that not only do mammalian cells absorb bacteriophages, but they appear to use them as a resource to enhance growth! journals.plos.org/plosbiology/ar… This work was led by @marion_bichet and out on World Phage Week! #WorldPhageWeek

@mattdjohansen @UTS_Science Congratulations Matt! Well deserved!

Happy to announce that I’ve been awarded the UTS Chancellor’s Research Fellowship (CRF) for 2024! This will support my research into understanding the host-pathogen interface of Mycobacterium abscessus infection in cystic fibrosis @UTS_Science
