BDUL, BDUR

Type: Interneuron
Connectivity:
- In MoW: BDU
- WormWiring: BDULh, BDURh, BDULm, BDURm
- In Nemanode: BDU
In Wormbase: BDU, BDUL, BDUR
Lineage: AB arppaappp, AB arpppappp
Location: Lateral. Left and right sides
of the anterior half of the body.
Description: Bipolar neurons with processes running along the excretory canal. The anterior processes enter the nerve ring via the deirid commissure where their primary synaptic input is from ALM.
Neurotransmitter/ Neuropeptide:
- NLP-1; neuropeptide-like protein
- NLP-15; neuropeptide-like protein
(Nathoo et al., 2001)
Innexin expression:
- CHE-7 (only in dauer)
- INX-2
- INX-7
- INX10a
- INX-19
- UNC-7
- UNC-9
(Altun et al., 2009; Bhattacharya et al., 2019)
Receptor expression:
- GLR-8; glutamate receptor subunit
- SER-2; tyramine receptor (a splice variant)
(Tsalik et al., 2003; Brockie et al., 2001)
Function:
- Guidance for AVM process outgrowth during L1 (Walthall and Chalfie, 1988)
Reporters:
- At CGC:

BDUL (AB arppaappp) development in the embryo. Dorsal view. Bottom is left side of the embryo. Spheres indicate individual nuclei. Black sphere: ancestors of BDUL (since last BDUL ancestor has not yet gone through its final division, the black sphere seen at the end of this movie is still AB arppaapp); dark grey spheres: apoptotic cells; other cells follow the WA color code (after they acquire specific cell or tissue identities). 0 min is fertilization.
