Huntington’s disease vasculopathy is barrier-type-selective and arteriolar-dominant with spatially-coupled astrogliosis and reversible by S1pr1 stimulation
Brain vascular barriers are dysfunctional in many neurological disorders, including Huntington’s disease (HD), but which vessels are affected and how remains unclear. Using in vivo two-photon microscopy in R6/2 HD-model mice, we reveal a striking divergence in barrier dysfunction. Surface vessels of the blood-cerebro...
