John Blair @jblairsci.bsky.social · 17/02/2026Check out our new paper that @abradu.bsky.social does a great job of explaining here!!! If you have any questions or want to try to use this tech please reach out!!! 121
John Blair @jblairsci.bsky.social · 23/10/2025The second paper I want to highlight was led my Izzy Grabski, where she developed a new method of "RNA Fingerprinting" to map transcriptional responses to perturbation dictionaries www.biorxiv.org/content/10.1...biorxiv.orgMapping transcriptional responses to cellular perturbation dictionaries with RNA fingerprintingSingle-cell perturbation dictionaries provide systematic measurements of how cells respond to genetic and chemical perturbations, and create the opportunity to assign causal interpretations to observa... 100
John Blair @jblairsci.bsky.social · 23/10/2025I wanted to highlight two recent papers from myself and colleagues! In the first, we develop a method, FlexPlex, that leverages the 10x Genomics Flex kits to capture RNA, intracellular protein and guide RNAs in single cells with high resolution multiplexing www.biorxiv.org/content/10.1...biorxiv.orgIterative, multimodal, and scalable single-cell profiling for discovery and characterization of signaling regulatorsCell signaling plays a critical role in regulating cellular state, yet uncovering regulators of signaling pathways and understanding their molecular consequences remains challenging. Here, we present ... 110
John Blair @jblairsci.bsky.social · 06/03/2025Excited (again) to see this paper finally in (pre)print! We did single-cell sequencing on our TSC model organoids and observed strong signatures of reactive astrogliosis (neat)- then we looked at resected patient brain tissue and saw the same thing! (More neat!) www.biorxiv.org/content/10.1...biorxiv.orgmTORC1 activation drives astrocyte reactivity in cortical tubers and brain organoid models of TSCTuberous Sclerosis Complex (TSC) is a genetic neurodevelopmental disorder associated with early onset epilepsy, intellectual disability and neuropsychiatric disorders. A hallmark of the disorder is co... 161
John Blair @jblairsci.bsky.social · 28/02/2025Happy that my first paper from my Postdoc is out where we perform Phospho-seq, a single-cell ATAC-sequencing with intracellular protein quantification in human brain organoids: www.nature.com/articles/s41...nature.comPhospho-seq: integrated, multi-modal profiling of intracellular protein dynamics in single cells - Nature CommunicationsHere, the authors demonstrate Phospho-seq, a single-cell multiomics method capable of quantifying chromatin accessibility alongside intracellular proteins, including post-translationally modified prot... 281
