General Information
Term larval Dh44 neuron of pars intercerebralis ID (Ontology) FBbt:00047128 (Fly Anatomy)
Definition Diuretic hormone 44 (Dh44)-expressing neuron having a cell body located in the larval pars intercerebralis (PI). There are three of these cells per hemisphere, and they also express leucokinin receptor (Cabrero et al., 2002). Its dendrites extend ventrally and its axon crosses the midline, loops posteriorly, then anteriorly, joining the nervus corporis cardiaci (Huckesfeld et al., 2021). It has peptide release sites in the aorta and corpus cardiacum (Huckesfeld et al., 2021).[ FlyBase:FBrf0152168 FlyBase:FBrf0210278 FlyBase:FBrf0232426 FlyBase:FBrf0249161 ]
Also Known As "CC/A-PI 3" ; "larval DH44 PI neuron" ; "larval DH44+ PI neuron" (for all, see Synonyms field below)
Comment Distinct from insulin-secreting cells, SIFamide cells and dromyosuppressin cells in the PI (Park et al., 2008). CC-PI 3 could not be identified unambiguously and not well described in Siegmund and Korge (2001) - FBrf0134726, mapped to Dh44 cells in Huckesfeld et al. (2021).
