Top Highlights

  • Hypothalamic tanycytes generate acute hyperphagia through activation of the arcuate neuronal network
  • tanycytes, engineered to express channelrhodopsin, can activate arcuate neurons to induce acute hyperphagia when activated by light.
  • Activation of tanycytes ex vivo depolarized orexigenic (neuropeptide Y/agouti-related protein; NPY/AgRP) and anorexigenic (proopiomelanocortin; POMC) neurons via an ATP-dependent mechanism.
  • activation of tanycytes triggered acute hyperphagia only in the fed state during the inactive phase of the light–dark cycle.
  • we also demonstrated that tanycytes can induce membrane potential changes in POMC-expressing neurons.
