ORN_DL2v
ID: FBbt_00051495
Olfactory receptor neuron that expresses the Ionotropic receptor (Ir) 75c and the co-receptor Ir8a (Prieto-Godino et al., 2017; Benton et al., 2025. Its dendrite transduces signals from antennal coeloconic sensillum ac3 type II and its axonal terminals are found in glomerulus DL2v (Prieto-Godino et al., 2017, bilaterally (Schlegel et al., 2021. It has a stronger response to propionic acid and a weaker response to butyric acid, compared to Ir75b neurons (Prieto-Godino et al., 2017. It develops from an Nab precursor (Benton et al., 2025. There are approximately 12 of these cells per antenna (Schlegel et al., 2021. (Prieto-Godino et al., 2017, Schlegel et al., 2021, Benton et al., 2025)
Prieto-Godino et al., 2017 showed that these cells are distinct from the Ir75b cells and that previous belief of co-expression was due to transcriptional run off from Ir75c.
