Happy New Year, all! Reminder that the deadline for abstract selected talks is Jan 7th for @keystonesymposia.bsky.social meeting "Beyond Antibiotics: Emerging Strategies Combating Bacterial Infection." Register today and join us in Breckenridge!! It is going to be an awesome meeting!

It's not too late to get your flu shot. Flu circulates year round but more intensely during flu season. For N. hemisphere: Onset: October–November Peak: December–February (most often January) Decline: March Tail end: April–May (occasionally later) This is why we give shots until the end of February

Friday we lost a brilliant mind, colleague, and friend to her battle with pancreatic cancer. Those who knew her will remember Helene Andrews-Polymenis for her warmth, generosity and leadership. She will be missed by many. RIP

Excited to share research co-led by Gabby & Adam in @jem.org! Grateful to the NIH & @scripps.edu for support.

I am excited to share that our work, in which we have dissected the signals driven by the nucleoside-modified mRNA and LNP components of mRNA vaccines that regulate germinal center (GC) responses, is now published in Cell! www.cell.com/cell/fulltex...

I'm happy to share a perspective that @soniamodilevsky.bsky.social and I wrote about a new and exciting paper in @science.org with big implications for IBD. Check it out: A bacterial toxin disarms gut defenses against inflammation | Science www.science.org/doi/10.1126/...

Very excited to share our latest work in Science on metagenomic editing (MetaEdit) of the gut microbiome in vivo & directly modifying unculturable immune-modulatory SFB bug in the small intestine. 🦠🧬🛠️ www.science.org/doi/10.1126/...

Nov issue of #Science #Immunology out now! This week: exTH17 cells sustain #IL17 –independent rheumatoid #arthritis; CXCR4+ mesodermal progenitors → rostral blood vessels, prodefinitive hematopoiesis, & postnatal tissue #macrophages; & how #Bcells acquire antigens from #parasites! scim.ag/4qQA6Q6

BREAKING: Pennsylvania voters approve to retain three state Supreme Court justices, NBC News projects, preserving Democrats’ 5-2 majority on the state’s high court.

Scripps Research Prof. Luc Teyton has received a $3.2M grant from the NIDDK to study how VAFs—rare pancreatic cells involved in antigen presentation—may contribute to type 1 diabetes. In collaboration with Asst. Prof. Joseph Jardine, the team will examine how inflammation disrupts immune tolerance.

Great primer from #NobelPrize winner Dr. Mary Brunkow on @npr.org's Here & Now: how FOXP3 and T regs help keep the immune system from harming the body. (~6 min) @wbur.org 🎧 www.wbur.org/hereandnow/2...

Immunization against respiratory syncytial virus delivered to infants following birth is safe and provides high antibody levels, regardless of the mother’s RSV vaccination status, according to new research presented at #IDWeek2025. bit.ly/3J9fIbS

All Democrats want is to lower health care costs for Americans. Republicans in Congress won’t even come to the table. How out of touch are they that they can't see we are in a health care crisis?

Thrilled to share my promotion to Associate Professor with tenure at @pitt-immunology.bsky.social! Huge thanks to my incredible lab, collaborators, department, colleagues, family & friends. Science is a team effort, and I'm so proud of our work & excited for what's next! Stay tuned!

Huge congratulations not only to the team leaders, but all the students, technicians and expert scientists who did the work that underpins this discovery. Their work, and the work of those following in their footsteps, is changing the future for autoimmune, transplant and oncology patients!

New commentary co-authored w/ collaborators Liat Shenhav & Mike Silverman 🧪🤱🏻 We are intrigued by weaning: - How does it affect the infant #microbiome? Immune development? - Is it the stopping of milk, or the starting of other foods that drives these processes? www.sciencedirect.com/science/arti...

Interaction between breast milk antibodies and gut microbes shape immune responses during weaning @science.org www.science.org/doi/10.1126/... www.science.org/doi/10.1126/...

Congratulations!!!! Well deserved! Tregs rock!

The whole Molecular Mucosal Immunology group is very excited to be part of the BIIE! This solidifies the Oxford-Switzerland collaboration that defines my group and provides the support and environment we need to get our ideas out into the world! Those gut pathogens had better watch out 😉🧪🧫🔬

Dr. Meghan Koch from @fredhutch.org has discovered a biological mechanism sprung in the first week of life that trains a mouse pup’s #ImmuneSystem to tolerate harmless gut bugs and new foods. ⚗️ Abstract: https://bit.ly/4nt6qGh 📰 Press release: https://bit.ly/46N7vBY

I'm having this surreal realization that standing up for evidence and data has become a politically polarizing position, and I don't know what to do about that.

It’s #MucosalMonday! 🎙️ A new episode of the Mucosal Immunology podcast drops next Monday, Sept 29. Until then, catch up with “Timing Exposure to Microbes” featuring Dr. Michael Silverman, brought to you by SMI and @mucosalimmunol.bsky.social Listen here -> bit.ly/4lxNC7F

Thanks so much! So glad to hear.

Kudos for @lizgreenspan.bsky.social

I’ve spent a good chunk of my career relying on American science and engineering to keep me alive. Yesterday, RFK Jr. testified at the U.S. Senate Finance Committee. It was sad to see him try to destroy the life’s work of so many American scientists. He shouldn’t be in this job.

I am here to say vaccines are awesome because guess what Denmark is close to completely eliminating the two most dangerous HPV strains (serotype 16 and 18) and with the cervical cancer.I think that is bloody AMAZING!!!! bit.ly/4pbHxjT

Come and be my colleague at the Dunn School! It‘s a brilliant place to work and exciting to be building up our immunology team. Do apply. Do pass on the news 💉🧬🦠🔬🧫

Happy to see the preview @joeyzacks.bsky.social and I wrote on the excellent paper recently published by the Gibbons Lab @gibbological.bsky.social is in press! I'd encourage folks interested in bacterial pathogenesis or microbial ecology to check out the preview and the research article!

Happy to team up with @microbe-enjoyer.bsky.social to highlight fantastic work by @gibbological.bsky.social, Alex Carr, and colleagues using community scale metabolic models to predict risk for C. difficile colonization! See the initial study here: www.cell.com/cell-systems...

Out today! www.science.org/doi/10.1126/... From @kknoop.bsky.social & myself on early life immune development & the beautiful publication from Megan Koch & M Shenoy www.science.org/doi/10.1126/... Take home message: timing of early life exposures, milk IgG here, is critical for immune development.

@michael-silverman.bsky.social and I discuss how new findings from Megan Koch’s lab highlight the importance of maternal guidance during early life helps prepare offspring for a life of immune health. www.science.org/doi/10.1126/...
