interoceptive SEZ neuron
ID: FBbt_00048518
Neuron that predominantly arborizes in the subesophageal zone (SEZ) and is involved in the regulation of feeding behavior (Jourjine et al., 2016. It expresses the TRPV channel nanchung and detects decreases in osmolality (Jourjine et al., 2016. It expresses Ilp3 and has presynapses in the SEZ (Gonzalez Segarra et al., 2023). There are two of these per hemisphere (Jourjine et al., 2016. (Jourjine et al., 2016, González Segarra et al., 2023)
Two other SEZ neurons also express nan (Jourjine et al., 2016. Ilp3, but not other Ilps, required in ISNs for function in ingestion (Gonzalez Segarra et al., 2023).
