General Information
|
| Term |
larval PTTH neuron of pars lateralis |
ID (Ontology) |
FBbt:00007457 (Fly Anatomy) |
| Definition |
Larval neurosecretory neuron that secretes prothoracicotropic hormone (PTTH) and innervates the prothoracic gland (Siegmund and Korge, 2001; McBrayer et al., 2007). It has its soma in the cortex of the lateral protocerebrum (Siegmund and Korge, 2001). It runs along the anterior brain at the cortex/neuropil interface, forming dendritic collaterals, before traversing the midline and entering the contralateral nervus corporis cardiaci to reach the ring gland (Siegmund and Korge, 2001; Huckesfeld et al., 2021). Its peptide release sites are found in the corpus cardiacum and the prothoracic gland (Siegmund and Korge, 2001; Huckesfeld et al., 2021). It expresses corazonin receptor and has close contact with corazonin neurons in the prothoracic gland (Imura et al., 2020). There are two of these cells per hemisphere (Siegmund and Korge, 2001).[ FlyBase:FBrf0134726 FlyBase:FBrf0201640 FlyBase:FBrf0245906 FlyBase:FBrf0249161 ] |
| Also Known As |
"larval l-NSC PTTH" ; "larval prothoracic gland innervating neurosecretory neuron of the lateral protocerebrum" ; "PG neuron" (for all, see Synonyms field below) |
| Comment |
McBrayer et al. (2007) used enhancer trap expression to confirm that their PG neurons are identical to the PG-LP neurons identified by Siegmund and Korge (2001). |
