The immunology of stroke and dementia
Ischemic stroke and vascular cognitive impairment are global health threats. Recent research has uncovered a previously underappreciated dynamic interplay between brain-resident, meningeal, and systemic immune cells. Iadecola and Anrather discuss the neurovascular immune factors that play a central role in the overlap between neurovascular pathologies and Alzheimer’s disease and in the complications associated with Aβ immunotherapy for Alzheimer’s.
