TNF‐α reduces cerebral blood volume and disrupts tissue homeostasis via an endothelin‐ and TNFR2‐dependent pathway

Abstract

TNF-alpha expression is elevated in a variety of neuropathologies, including multiple sclerosis, cerebral malaria and HIV encephalitis. However, the consequences of such high cerebral TNF-alpha expression remain unresolved. Here, using MRI, we demonstrate that a focal intrastriatal injection of TNF-alpha causes a significant, acute reduction (15-30%) in cerebral blood volume (CBV), which is dependent on TNF-alpha-type 2 receptor (TNFR2) …
