Hyperlipidemia induces hippocampal inflammation and loss of vascularity and can be rescued by silencing RIPK1 (opens in new tab)

Vascular cognitive impairment (VCI) is a common form of dementia associated with cerebrovascular dysfunction and chronic inflammation. Impaired cerebral perfusion is a result of atherosclerotic plaque build-up in the medium and large arteries in the brain and is exacerbated by numerous inflammatory triggers, including aging, high blood pressure, high cholesterol, and smoking. Previously, we demonstrated that receptor-interacting protein 1 kinase (RIPK1) promotes the progression of aortic athe...
