Excited for start of AAIC!

I’ll be giving talk Tuesday afternoon on unique population of AD-relevant macrophages we have identified in CSF via scRNA-seq:

3 reviews on planning, execution, & validation of transcriptomic experiments in neuroscience published in @natureportfolio.bsky.social #NatureNeuroscience.
A MUST READ if you're doing transcriptomics.
3 reviews, an amazing editorial, a beautiful cover – this is the issue of the year!

Could one envision a synthetic receptor technology that is fully programmable, able to detect diverse extracellular antigens – both soluble and cell-attached – and convert that recognition into a wide range of intracellular responses, from gene expression and real-time fluorescence to modulation..

Muzz Haniffa’s group with yet another landmark paper on the yolk sac, hematopoiesis, and organogenesis (as well as its differences between humans and mice). Not bad for an alleged dermatologist (yes, I know, skin GvHD… but still!)
