Natural maternal immunity protects neonates from Escherichia coli sepsis - Nature Neonatal sepsis caused by Escherichia coli is associated with reduced transfer of pathogen-specific maternal antibodies and, in a mouse model, can be prevented by maternal preconceptual&nbsp...

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...

It's just oligos that map to highly conserved DNA so one batch fits everyone. If we're going to be so dishonest to begin with, we might as well go all in πŸ˜‚

I don't understand the basis of the NIDDK cut. Surely it fits the newly stated mission re chronic diseases/"out diet is killing us" quite well. Awful is right.

Interesting 🧡. IANAE so won’t comment on the science beyond noting that phase separation (in biology) is highly contentious (see e.g. genesdev.cshlp.org/content/33/2...). But it does bring up issues around publishing and editorial decisions 1/n

Populist Dems won. Moderate Dems won. We won in blue states. We won in purple states.

Maybe the take is that (a) people think Trump is out of control; and (b) people like Dems when we're taking a stand and fighting for what we believe in - as we have been for the last month.

Love Nebraska so much, these lines always give me the chills:

"Now my ma she fingers her wedding band
And watches the salesman stare at my old man's hands
He's tellin' us all 'bout the break he'd give us
If he could but he just can't
Well if I could I swear I know just what I'd do"

2/2 So, some TCR may be more prone to become Tregs or whatnot, but without tracking responses to the same epitope for different TCR it's really hard to know if there is TCR determinism (which I have no issue with) versus some facet of the stimulation (loosely "environmental") that drives this.

1/2 This is a very nice paper but I'm not sure I agree fully with the conclusion (reading on the train on my phone, may have missed something). To my mind, this data shows that a given TCR will repeatedly adopt a particular cell fate when encountering the same antigen derived from the same source.

Happy to share new work from #theonlylabever, lead by the phenomenal @sltai.bsky.social - who developed a tool to study the biology of ILC3s, identifying their role in controlling CSF2-dependent myeloid cells. πŸ€—

Was it ever alive? I joined because I heard it was like old Twitter but I never see much in the way of decent science conversation on here. Maybe people have just abandoned social media.

It's more than 20 years old, so obviously doesn't discuss many of the amazing discoveries since, prominent among them being the tissue repair functions of Tregs, identifying them as immune system regulators not merely suppressor T cells.

I've noted for a long time a desire among many to try & write particular people out of the narrative of the history of Treg research. This review, by the one person everyone agrees is pivotal, provides an accurate assessment for those who don't know the field:

I think, Fiona Powrie, Ethan Shevach, Jeff Bluestone, Diane Mathis and Christoph Benoist all would lay claim too. Don Mason is dead, but he probably started his studies in the area at a similar time to Sakaguchi.

All praise to him is well warranted.

It is strange that there hasn't been an award for T cells/B cells, given that there is sufficient consensus that Miller and Cooper could share it.
