tanycyte
A specialized elongated ventricular ependymal cell with one or more processes that extend into the brain parenchyma or associated blood vessels where they contact blood vessel endothelial cells and/or neurons.

They are involved in hormonal regulation, gatekeeping molecules between the bloodstream and cerebrospinal fluid, metabolic sensing, and regulating food intake.
