dorsal organ warming cell

ID: FBbt_00051986

Ir68a, Ir25a and Ir93a -expressing neuron of the dorsal organ ganglion (DOG), activated by temperature increases (Hernandez-Nunez et al., 2021). All three of these Ir genes are necessary for heating-induced activity of these cells, with Ir68a specifying warming, rather than cooling sensitivity (Hernandez-Nunez et al., 2021). Two of these cells are found in each DOG and each projects to a different antennal lobe glomerulus, distinct from the one targeted by the cool cells, in the posterior dorsal antennal lobe (Hernandez-Nunez et al., 2021). The sensory dendrites of these neurons do not exhibit the membrane infoldings seen in the cool cells and they extend a thin dendrite into the central dome sensillum (Hernandez-Nunez et al., 2021).
