abdominal 9 DUM neuron [FBbt_00047553]

Unpaired median neuron of abdominal neuromere 9 (terminal neuromere) of the larval ventral nerve cord (VNC). Its cell body is on the VNC midline in a dorsal location and it arborizes mostly in the dorsal part of A9, but neurites also branch extensively in the dorsal and medial neuropil of A8 and reach the posterior part of A7. It is tyraminergic and octopaminergic. There are two of these cells.

Larva Nervous system Octopaminergic Tyraminergic

Unpaired median neuron of abdominal neuromere 9 (terminal neuromere) of the larval ventral nerve cord (VNC). Its cell body is on the VNC midline in a dorsal location and it arborizes mostly in the dorsal part of A9, but neurites also branch extensively in the dorsal and medial neuropil of A8 and reach the posterior part of A7. It is tyraminergic and octopaminergic. There are two of these cells.

Vomel and Wegener, 2008 (FBrf0210246) reported that these cells were located in abdominal neuromere 8. For neurotransmitter expression analysis, Vomel and Wegener, 2008 used Tdc2-GAL4 (tyrosine decarboxylase - implies presence of tyramine) and anti-Tbh (tyramine beta-hydroxylase - implies presence of octopamine). Selcho et al., 2012 used Tdc2-GAL4, validated with anti-Tbh, anti-p-tyramine and anti-conjugated octopamine, to visualize tyraminergic and octopaminergic neurons.
