Tolerance to intestinal microbes and the developing fetus share similar immunological mechanisms Pregnancy is remarkable in that mothers tolerate the developing fetus expressing immunologically foreign paternal antigens. These foreign antigens stimulate rejection in other contexts, such as organ ...

Thanks for highlighting our work with the other outstanding recent discoveries

Maternal Krüppel-like factor 2 (KLF2)+ CD4 T cells promote fertility and fetal tolerance | PNAS Pregnancy requires expanded maternal tolerance to semiallogeneic fetal-expressed antigens to protect against fetal loss and other pregnancy complic...

Mama's T cells also need KLF2 for promoting fertility and optimal pregnancy outcomes.

I keep learning new ways maternal antibodies protect infants! The latest from @babiesresearch.bsky.social on protection against E. coli sepsis and new potential vaccine targets.

So nice to see a whole issue of @cp-trendsimmuno.bsky.social dedicated to the topic of perinatal and early life immunity, especially the great contribution by new people bringing new perspectives to this important but still grossly understudied developmental window

Thank you @lizszabo.bsky.social for this beautiful summary

New research looks at mother's antibodies that protect babies from E. coli Cincinnati Children's study reveals that many newborns are protected from serious bacterial infections by antibodies passed from mother before birth.

Dr. Sing Sing Way joined Cincinnati Public Radio's Cincinnati Edition to discuss his new study on how maternal antibodies protect newborns — and what this could mean for preventing serious infections.

Thank you for this nice summary

Thank you Vipul and Stephanie for this lovely invitation, to share so many immunological secrets we can learn from studying mothers and babies. You are building a great program there at @immunology-nu.bsky.social and I am honored to spend the day learning from you all

Mothers’ Exposure to Microbes Protect their Newborn Babies Against Infection - Research Horizons

New research led by our experts finds newborns who develop severe E. coli infection have lower levels of protective antibodies from their mothers. The study, published in Nature, could help identify high-risk infants and guide new prevention strategies. Learn more and see what's next:

Another twist to why newborn babies more vulnerable to infection. Beyond immune cell immaturity, layering, active suppression... maternal pathogen-targeted antibodies still protect. Grateful @Nature sharing this hopefully uplifting glass half (99.9%)-full perspective www.nature.com/articles/s41...

Congrats to Dr. Sing Sing Way on being elected to @nam.edu —one of the highest honors in health & science. His pioneering research on pregnancy & early-life immunity is transforming how we understand & protect maternal & infant health. Read more: scienceblog.cincinnatichildrens.org/sing-sing-wa...

Thanks so much
@cincyresearch.bsky.social
for this post, and
@nam.edu
for highlighting the work we are doing to understand ways to improve infant and child health through improved pregnancy outcomes

Thanks so much for highlighting our work. Microchimeric cells can teach us alot of immunology
