RICL, RICR
Function:
- Dopaminergic CEP neurons are presynaptic to both the octopaminergic RIC neurons and the SIA neurons. In the absence of food octopamine is released from the RIC neurons and humorally activates the octopamine receptor SER-3 in the cholinergic SIA neurons (in the absence of food, activation of DAF-3 by loss of DAF-7 signaling leads to increased octopamine signaling from the RIC neurons and the cyclic AMP response element binding protein becomes activated in SIA). Dopamine signaling suppresses octopamine signaling through a mechanism that requires two D2-like dopamine receptors DOP-2 and DOP-3 , located on both the SIA neurons and RIC neurons

RICL (AB plppaaaapp) development in the embryo. Dorsal view. Bottom is left side of the embryo. Spheres indicate individual nuclei. Black sphere: ancestors of ADEL (since last RICL ancestor has not yet gone through its final division, the black sphere seen at the end of this movie is still AB plppaaaap); dark grey spheres: apoptotic cells; other cells follow the WA color code (after they acquire specific cell or tissue identities). 0 min is fertilization. Click on the movie for higher resolution rendition (by A. Santella & Z. Bao). |
