larval abdominal ganglion Leucokinin neuron

ID: FBbt_00110053

Larval neuron that expresses Leucokinin (FBgn0028418) whose cell body is located ventrolaterally in each neuromere of the abdominal ganglion. Each neuron produces a pair of axons, one of which projects dorsally and emerges from the ventral ganglia through an anterior segmental nerve of each hemineuromere. The other branch divides centrally into two branches: one send its neurites to the anterior ABLK and the other ventrally to the posterior ABLK. From each segmental nerve one axon emerges that synapses to the adjacent segment border muscle, close to the spiracle (Haro et al., 2010; Landgraf et al., 2003). These synapses lack the typical morphology of motor-neuron synapses (Landgraf et al., 2003) and are not glutamatergic (Haro et al., 2010). There is one pair of neurons in each of seven abdominal neuromeres (de Haro et al., 2010).

The more anterior ABLK neurons are connected to the leucokinin SELK neuron of the subesophageal ganglion in the dorsal-medial tract (de Haro et al., 2010). Landgraf et al. (2003), also detected leucokinin positive terminals on A1-7 ventral longitudinal (VL) muscles. It is not clear where these neuron originate from.
