Sex hormones and chromosomes work in tandem to impact immune responses, with estrogen influencing class-switched memory B cell frequency exclusively in humans with an XX chromosomal background. From @hlpeks.bsky.social, @bcellsrosser.bsky.social, Coziana Ciurtin et al. rupress.org/jem/article/...
And thank you to UCL news for highlighting our work in this article! 😀😀😀
Great coverage of the recent JEM paper by @hlpeks.bsky.social, @emmaschambers.bsky.social, @bcellsrosser.bsky.social, Coziana Ciurtin, and colleagues. See the original paper here: rupress.org/jem/article/...
A new UK-led research group, including @ucl.ac.uk's Prof Lucy Wedderburn (@uclchildhealth.bsky.social), Prof Coziana Ciurtin & Dr Polly Livermore, aims to improve arthritis care by defining for the first time what remission truly means. Funded by £3m from Arthritis UK www.ucl.ac.uk/news/2025/de...
Did you know women may be naturally better at fighting certain infections than men?
A UCL study funded by the Foundation finds women have a higher proportion of key immune cells between puberty & menopause. 💪🦠
Tune in to @bcellsrosser.bsky.social on BBC R4’s Inside Health to learn more!
So excited to see this out please read the paper, article and listen to us on the radio! Big thanks to @uclnews.bsky.social, our superstar postdoc @hlpeks.bsky.social, co-senior author Prof Coziana Ciurtin and collaborators @emmaschambers.bsky.social
Congratulations @hlpeks.bsky.social great work. So important to understand sex differences in immunity
If you have 30 seconds pretty please could you vote for our research: 'Option 5. Sex differences in the immune system' at the link below! We truly appreciate your support!! 🔬🌟🙏🏻
Thanks for the highlight @arrdept-ucldom.bsky.social ! Bernard very happy you captured his good side 😺
And please give a listen to our research featured on BBC Radio 4's Inside Health show! Lucy and Lizzy did a wonderful job talking about our findings! (We're in the second half) @bcellsrosser.bsky.social www.bbc.co.uk/sounds/play/...

Until menopause women have more key immune cells, which may explain why they're less prone to some infections than men, finds a @jem.org study from @arrdept-ucldom.bsky.social including Dr Hannah Peckham @hlpeks.bsky.social & Dr Lizzy Rosser @bcellsrosser.bsky.social

Thrilled to finally share our paper on how sex hormones and sex chromosomes interact to affect B cell class-switching!🥳 Diversity & inclusion in research recruitment = better science for all!😎 Thanks to @[email protected]@arrdept-ucldom.bsky.social for ++ hard work!🌟
