My policy on this app is to follow as many scientists as possible. I want a robust, highly varied network of people to discuss all biological research. Especially students

Love your work. It’s inspiring!

We’re excited to report work led by postdoc Jennifer Porat in the lab, finding that DNA accumulates on the surface of living cells and that the secreted extracellular protein DNASE1L3 can modulate its levels on B and T cells. With a new twist for ATAC-seq as well www.biorxiv.org/content/10.1...
DNASE1L3 surveils mitochondrial DNA on the surface of distinct mammalian cells
The extracellular space is a critical environment for discriminating self versus non-self nucleic acids and initiating the appropriate immune responses through signaling cascades to relay information ...

I always associated Wildin with the scurfy story too

I guess the focus was on foxp3 or else one could’ve included Maria Grazia Roncarolo and it’s a shame rudensky was left off since he was right there on foxp3 huh

I’m just a big fan of his early work and perseverance to study something everyone else had given up on is all :)

Twenty-four years ago today, our paper “A forkhead-domain gene is mutated in a severe speech and language disorder” was published: www.nature.com/articles/350....
A personal thread about the ups & downs of the journey we took to get to that point....1/n
🗣️🧬🧪
Image shows the first two printed pages of the paper “A forkhead-domain gene is mutated in a severe speech and language disorder” by Cecilia Lai and colleagues, published in Nature in 2001 (volume 413, pages 519-523). The abstract reads as follows:
Individuals affected with developmental disorders of speech and language have substantial difficulty acquiring expressive and/or receptive language in the absence of any profound sensory or neurological impairment and despite adequate intelligence and opportunity. Although studies of twins consistently indicate that a significant genetic component is involved, most families segregating speech and language deficits show complex patterns of inheritance, and a gene that predisposes individuals to such disorders has not been identified. We have studied a unique three-generation pedigree, KE, in which a severe speech and language disorder is transmitted as an autosomal-dominant monogenic trait. Our previous work mapped the locus responsible, SPCH1, to a 5.6-cM interval of region 7q31 on chromosome 7. We also identified an unrelated individual, CS, in whom speech and language impairment is associated with a chromosomal translocation involving the SPCH1 interval. Here we show that the gene FOXP2, which encodes a putative transcription factor containing a polyglutamine tract and a forkhead DNA-binding domain, is directly disrupted by the translocation breakpoint in CS. In addition, we identify a point mutation in affected members of the KE family that alters an invariant amino-acid residue in the forkhead domain. Our findings suggest that FOXP2 is involved in the developmental process that culminates in speech and language.

Here’s part 3 of our four part Better Offline case against generative AI. I walk you through how “AI replacing software engineers” is a myth - and how Microsoft only has 8 million active paying customers for Microsoft 365’s AI Copilot.

I’ve really enjoyed these. Keep up the good work

Happy to share the latest work from Preeti Sahu, with Adriana Sanchez-Danes on the biomechanics of cell fate choices during tumor initiation! We implement/test a 3D vertex model with proliferation and fate choices for multilayered tissues! See 🧵 below (1/n) bit.ly/3ZXxJzk

Cell type classification bears resemblance to the labubu market space in that the market demands ever more rare versions to feed publishing demands

Ohhh my favorite question
jeffmold.bsky.social
Cdkn1b is listed as a “cell cycle regulator” but I always think of these genes as “brakes” to prevent DNA damage from being inherited during division. But maybe I’m wrong?
