Epidemiology and Management of Malignancies in Patients with Inborn Errors of Immunity - An ESID Registry Study of 19,959 Patients https://www.medrxiv.org/content/10.1101/2025.08.26.25334420v1

Cover of The Lancet's August 23, 2025 issue. Quote on cover reads: "Either through incompetence or disinformation, the actions of this movement pose the greatest threat to the health of Americans and millions of people globally."

The week beginning Aug 4 was the most dangerous, tragic week of RFK Jr’s tenure yet.

A Lancet Editorial outlines why—unpacking a movement that seeks to discredit mainstream medicine and portray institutions and experts as enemies, not partners. tinyurl.com/4zppw6ay

#ImmunologyWithoutBorders

Doublespeak…

Wrong target audience, but anyway: a VERY recommended exhibition by www.gittaseidel.com

Great work! …more leukemia-associated genes are found to underlie IEI/PIDs!

Very proud of this new paper describing a novel human immune defect caused by ASXL1 deficiency.
We really had to open the genomics tool box to solve this one, including neat tricks like calculating the epigenetic age.
All led by Dr. Catherine Biggs!

Viewpoint: To effectively reduce drug costs, the US needs its own price negotiation framework rather than relying on international benchmarks, as proposed by the Trump administration.

Great review of what is becoming a more ‘common’ IEI with diverse phenotypes emerging

30-year @esidsociety.bsky.social registry analysis of 30,628 patients' longitudinal datasets show results of robust epidemiological studies on natural courses including diagnosis, treatment, and survival, supporting newborn screening and future AI applications in IEI. rupress.org/jhi/article/...

PS: after successful migration of all UK patients‘ datasets to the new ESID registry platform our registry now contains >35,000 datasets

Here it is: Proudly presenting our great collaboration report of the @esidsociety.bsky.social registry at @jhumimmunity.org on #IEI #PID THANKS to all contributors and untiring coauthors :) !! rupress.org/jhi/article/...

Attorney General Pam Bondi announces dismissal of charges against plastic surgeon accused of faking COVID-19 vaccine cards Attorney General Bondi announced she is dismissing charges against Dr. Michael Kirk Moore, a Utah plastic surgeon.

Pam Bondi has hailed as a hero and dismissed charges against a doctor who:

Injected children with placebo instead of COVID19 vaccine

Destroyed $28,000 worth of taxpayer-funded COVID19 vaccines

Sold fake vaccination cards so people could avoid the vaccine

His license is still active in Utah.

Our van der Veeken lab shows in a new study that the transcription factor Foxp3 is only needed in regulatory T cells during inflammation.

🔎Turning off Foxp3 boosts anti-tumor immunity without harmful side effects.
