Thanks Payal! It was lovely indeed!

New paper📢 - how many individuals are affected by an autoimmune disease. Together with epidemiology experts jonas Ludvigsson @ki.se we use 🇸🇪 population registry and find that 1/13 adults and 1/67 children are affected by autoimmunity: link.springer.com/article/10.1...

Recap 2023 via @petterbrodin.bsky.social @theguardian.com www.theguardian.com/science/2023... The term “immunity debt” was first introduced by French researchers in 2021. It refers to a population-wide effect rather than an individual-level one.

Why are more and more people suffering from #allergies and autoimmune diseases? The answer may lie in the development of the immune system in newborns @petterbrodin.bsky.social @ki.se has developed a technique to map #immunesystem development from a single drop of blood. tinyurl.com/3j22dyw8

Variation in the human immune system is largely driven by non-heritable influences @petterbrodin.bsky.social P. Brodin et al. Cell. 2015.

Weight loss improves health but What happens to cells in the fat during weight loss? Intriguingly, immune cell numbers decrease but their activated states persist w chronic inflammatory potential. Beautiful work from neighbors @mrc-lms.bsky.social Will Scott et al www.nature.com/articles/s41...

How can we clear persistent viruses and cure patients with #LongCOVID - led by @michaelpelusomd.bsky.social, Amy Proal @polybiorf.bsky.social www.sciencedirect.com/science/arti...

YES. Need to say this loudly and often! This 2.46x is also the short-term ROI. Long-term ROI (more difficult to estimate) may ~10x. Highest for any gov't spending. And the source of discoveries necessary for all new drugs (industry important too but without NIH funded science there's no foundation)

Even though some non-US scientist might see these massive cuts imposed on our US colleagues as an opportunity to get ahead, I do not. This decision will be negative for all of us as scientists…we all depend on each other and advance together…
