Preprint alert: Check out our latest work 'Electro-Calcium Uncoupling in Capillary Endothelial Cells Precedes Neurodegeneration in Alzheimer's disease'. We used Young 5xFAD mice to decipher neurovascular communication deficits in pre-symptomatic phase of AD.

Thanks @sorengrubb.bsky.social for creating this 🧡 to summarize the findings. Thanks @alleninstitute.org @hhmijanelia.bsky.social and @helenelab.bsky.social for the EM datasets.

First Preprint from my group @NIHIRP, where a summer project led by Vanshika Chaddha took unexpected turn into identifying Primary Cilia across the Brain Vasculature.
New avenues for NVC.
Amazing Collaboration with @sorengrubb.bsky.social, Carolyn Ott and Jennifer Lippincott-Schwartz.

TMC1 and TMC2 are cholesterol-dependent scramblases that regulate membrane homeostasis in auditory hair cells TMC1 and TMC2, the pore-forming subunits of the mechanoelectrical transduction (MET) complex in inner ear sensory hair cells, are essential for auditory and vestibular function. Pathogenic mutations in TMC1 are a leading cause of genetic hearing loss, but their underlying cellular mechanisms remain poorly understood. Here, we reveal that TMC1 and TMC2 are cholesterol-regulated lipid scramblases whose activity modulates plasma membrane asymmetry. Using reconstituted proteoliposomes and molecular dynamics simulations, we demonstrate that both proteins facilitate phospholipid translocation across membrane bilayers, a process tuned by cholesterol and enhanced by deafness-causing TMC1 mutations. We show that this scramblase activity correlates with TMC1-dependent externalization of phosphatidylserine and membrane blebbing in murine auditory hair cells, linking TMC1-dependent membrane homeostasis dysregulation to auditory sensory cell pathology. These findings identify TMCs as a novel family of lipid scramblases, advancing our understanding of MET complex biology and offering mechanistic insight into membrane-driven forms of hereditary deafness. ### Competing Interest Statement The authors have declared no competing interest.

🐭🧠 #PrecapillarySphincters (PS) at the #arteriole–#capillary junction rapidly dilate ~30% in seconds during #SensoryStimulationβ€”regulating #capillary #BloodFlow dynamically. Here we investigated whether they protect downstream microvessels during abrupt #BloodPressure surges πŸ§ͺ🧡

I am delighted to share the work of my amazing student Dominic Isaacs! Out today in PNAS (www.pnas.org/doi/10.1073/...), Dom beautifully used optogenetics to show that thin-strand pericytes in the brain can send long-range electrical signals to control arteriole diameter and brain blood flow.
