HLA-B*15:01 has been linked to protection from severe COVID, but this is not fool-proof. B*15+ individuals can still succumb to severe infections. Check out a recent study from Prof Kedzierska's lab 👇🏼 showing a lack of public TCR usage in B*15+ patients with severe COVID.

Why do some people get seriously ill while others don't? Our new study in @pnas.org investigated how a population of memory T cells influence #COVID severity Read the paper: go.unimelb.edu.au/4zkp Or our article here: go.unimelb.edu.au/2zkp @katherinekedz.bsky.social @thedohertyinst.bsky.social

Congrats Tejas! 🎉

Thrilled to share our new research led by Jane Davies @menziesresearch.bsky.social on First Nations people in the NT living with chronic hepatitis B. An important study that could inform better care: doi.org/10.1186/s128... #idsky #MedSky #HepSky #LiverSky

Happy Day of Immunology! I was delighted to host members of the public here at The Doherty Institute @thedohertyinst.bsky.social and guide a tour to showcase our research and teaching facilities, and give an overview of my research on how #pregnancy changes the immune system.

Single-cell immune profiling of third trimester pregnancies defines importance of chemokine receptors and prevalence of CMV-induced NK cells in the periphery and decidua https://www.medrxiv.org/content/10.1101/2025.03.24.25324489v1

‼️Preprint alert‼️ This is a study arising from my PhD thesis where we delve into the world of NK cells and pregnancy 🤰. Really glad to see it online and keen to hear any thoughts or feedback #immunosky

This is so cool, pregnancy takes guts!

Speaking of incredible women, my absolutely amazing mentor @katherinekedz.bsky.social is now on Bluesky🙌🏼, give her a follow!

What an insightful and inspiring panel discussion for International Women's Day. A timely reminder that we stand on the shoulders of giants who have paved the way for #WomenInSTEM, something we should not take for granted. Thanks to the SBS and the EMCRA association for hosting 🌸

Timely study by Katherine Kedzierska and Jamie Rossjohn and colleagues defining key structural features of #Tcell binding to circulating #influenza strains from 1918 to ~present #ImmunoSky www.science.org/doi/10.1126/...

It was great to present and hear about exciting research at the Impact of Initial Influenza Exposure on Immunity in Infants meeting at the NIAID. Always a pleasure to see @eksliger.bsky.social, @jcclab.bsky.social, @sschattgen.bsky.social, @pgtimmune.bsky.social, and to meet some new faces as well!
