It has previously been discovered that tanycytes—cells found in part of the brain that controls energy levels —detect nutrients in food and tell the brain directly about the food we have eaten.
Tanycytes do this by responding to amino acids found in foods, via the same receptors that sense the flavor of amino acids (“umami” taste), which are found in the taste buds of the tongue.
In the paper ‘Hypothalamic tanycytes generate acute hyperphagia through activation of the arcuate neuronal network.’ published today, the 8th June, in the journal PNAS, researchers from the School of Life Sciences at the University of Warwick, explain how tanycytes can increase appetite.
