Learning immunology from mothers and babies www.sciencedirect.com/science/arti... The maternal-fetal dyad can reveal strategies for improving pregnancy outcomes, but also how immunology works applicable to many other physiological contexts @mucosalimmunol.bsky.social @societymucosalimm.bsky.social

You asked, we answered — this time for our united #FreemanHrabowski Scholars and #HannaGray Fellows programs. A warm welcome into who's eligible, how the programs connect, and more, from our very own Science Program team members Mary Bonds & Lucy Corcoran. Applications open 11/3! bit.ly/fhs26 🧪

Allergen sensitization drives CCR8-dependent trafficking of ILC2s to lymph nodes, where they provide early IL-4 signals that selectively promote Tfh13 cells www.cell.com/immunity/ful... @cp-immunity.bsky.social @gowthaman.bsky.social @umasschan.bsky.social

Despite general systemic immune modulation during reproduction, the maternal intestine undergoes remodelling to strengthen innate defense to protect mothers & offspring from pathogens @nature.com @princeton.edu @aiinglim.bsky.social www.nature.com/articles/s41... www.nature.com/articles/d41...

Really enjoyed reading this!! Thank you so much for highlighting our work and for the thoughtful, constructive feedback that helped strengthen our study!!

LIMmunity 2nd brew: Motherhood comes with superpower: pathogen protection! 🤰🤱 www.nature.com/articles/s41... We often think moms are immunologically vulnerable during reproduction to tolerate the baby. But I always wondered: why would evolution make such a critical period of life so dangerous?

📢🎉@hhmi-science.bsky.social HHMI competition for the next cohorts of #HannaGray Fellows and #FreemanHrabowski Scholars opening 11/3/2026. Senior postdocs and faculty within 7 years of appointment. Up to $10M over 10 yrs, + salary & benefits. Spread the word and consider applying! bit.ly/4vhC0LA

Lim lab investigates: Helminth worm-infected mice give birth to pups with elevated anti-viral defenses in their lungs, leaving them more resistant to infection by respiratory viruses such as influenza and RSV. What causes these protective effects? molbio.princeton.edu/news/2026/wh...

We found maternal helminth infection can promote antiviral immunity in offspring 🤱🪱 www.cell.com/cell-host-mi... Don’t worry, we are not suggesting we reinfect everyone with worms! Instead, we identified a microbiota-derived metabolite, Indole-3-propionic acid, that enhances antiviral immunity!

New preprint to share! Incredible collab w/ Fei Chen’s lab: developed in vivo CRISPR screening platform for 🫁 epithelium, allowing single cell perturbation in post-flu repair. Take a peek to see what we found! Huge congrats to the leaders of this work @daisyah.bsky.social & @sundakao.bsky.social 🎉

We are hiring! The Brown Lab is looking for a computational biologist to join our team. If you enjoy working with single-cell and spatial genomics data and want to study how immune cells develop and function, we’d love to hear from you! Apply here: hhmi.wd1.myworkdayjobs.com/External/job...

🚀 We’re hiring a Postdoc! Seeking expertise in spatial metabolite imaging and/or mass spectrometry to study how host metabolism shapes immune responses. If you're creative, collegial, and excited to push boundaries, we’d love to hear from you. Please share! 🔗 www.nature.com/naturecareer...
