| Summary: | Tanycytes around the third ventricle and the adjacent mediobasal hypothalamus are crucial components to trigger photoperiodic responses in breeding and metabolism. In mammals, tanycytes are known to regulate hypothalamic thyroid hormone conversion, a process which is linked to seasonal reproduction. They are further involved in retinoic acid signalling, neurogenesis, and nutritional gatekeeping, all of which have been linked to the photoperiodic regulation of metabolism. The region is neuroanatomically conserved between mammals and birds but, apart from the hypothalamic thyroid hormone conversion, little is known about the functional roles of tanycytes in birds. We, hence, aimed to give a comprehensive characterisation of gene expressions in avian tanycytes and surrounding cells under different photoperiodic reproductive and metabolic states. For this purpose, we used the Svalbard ptarmigan (Lagopus muta hyperborea), a high-Arctic bird species which shows pronounced seasonal rhythms in breeding and body ... |
