Adds 14 new CL terms covering the major neurochemical and morphological cell types of the myenteric plexus, as requested by HubMap. All terms use temporary IDs (CL_99xxxxx) pending minting of permanent IDs.

Defined classes (EquivalentClasses)

  • CL_9900013: enteric neuron ∧ has_soma_location(UBERON:0002439) ∧ capable_of(GO:0014055) — acetylcholine secretion; autoclassifies stubby Dogiel I, IPANs, ascending interneurons
  • CL_9900014: enteric neuron ∧ has_soma_location(UBERON:0002439) ∧ capable_of(GO:0006809) — nitric oxide biosynthesis; autoclassifies spiny Dogiel I neurons

Post-review axiom changes

  • Removed SubClassOf(CL_9900009, CL_0008015) — spiny Dogiel type I neuron of myenteric plexus is no longer asserted as a subclass of inhibitory motor neuron.
  • Added SubClassOf(CL_9900001, CL_0007011) — Dogiel type II neuron is now also a subclass of enteric neuron (in addition to neuron).

Per-term metadata

Each term includes: definition with inline PMID citations, exact/related synonyms (abbreviations flagged OMO_0003000), SubClassOf parent axioms, RO_0002100 soma location to UBERON_0002439, IAO_0000233 tracker link, terms:creator, and terms:date.

Copilot follow the information below and create new CL for the terms described below:

-## Term 1: Intrinsic primary afferent neuron of myenteric plexus

Preferred Label: intrinsic primary afferent neuron of myenteric plexus

Definition: A sensory neuron of the enteric nervous system whose soma resides in the myenteric plexus and which functions as the afferent limb of intrinsic reflex circuits controlling motility, secretion, and blood flow. This neuron is characterised by Dogiel type II morphology (large smooth soma with multiple long axon-like processes), AH-type electrophysiology (prolonged afterhyperpolarization following an action potential), and is immunopositive for choline acetyltransferase (ChAT) and immunonegative for neuronal nitric oxide synthase (NOS1).

UBERON Terms:

  • UBERON:0002439 (myenteric nerve plexus) — soma location

Parent CL Terms:

  • CL:0007011 (enteric neuron)
  • CL:0000101 (sensory neuron)

Import Flags: None

Synonyms:

  • IPAN (PMID:34170401)
  • myenteric sensory neuron (PMID:34170401)
  • multiaxonal cholinergic myenteric sensory neuron (PMID:37355216)

Term 2: Interneuron of myenteric plexus

Preferred Label: interneuron of myenteric plexus

Definition: An interneuron of the enteric nervous system whose soma resides in the myenteric plexus. Interneurons of the myenteric plexus integrate sensory input from intrinsic primary afferent neurons (IPANs) and modulate motor output to smooth muscle and secretory epithelia by synapsing onto motor neurons and other interneurons within the plexus.

Parent CL Terms:

  • CL:0007011 (enteric neuron)
  • CL:0000099 (interneuron)

Import Flags: None

Synonyms:

  • enteric interneuron of myenteric plexus (PMID:34170401)

Term 3: Secretomotor/vasodilator neuron of myenteric plexus

Preferred Label: secretomotor/vasodilator neuron of myenteric plexus

Definition: An enteric neuron whose soma resides in the myenteric plexus and which controls mucosal secretion and blood flow by innervating secretory epithelia and submucosal blood vessels. This neuron is characterised by expression of vasoactive intestinal peptide (VIP). In mouse, two Glp2r+ subtypes have been identified: PSVN1 (VIP+, non-cholinergic) and PSVN2 (ChAT+, cholinergic). In human, only the VIP+ non-cholinergic subtype has been detected.

Import Flags: None

Synonyms:

  • PSVN (PMID:34170401)
  • VIP-positive secretomotor neuron (PMID:32888429)

Term 4: Intestinofugal neuron

Preferred Label: intestinofugal neuron

Definition: An enteric neuron whose soma resides in the myenteric plexus of the intestine and whose axon projects outside the gut wall to synapse on neurons in prevertebral sympathetic ganglia (celiac, superior mesenteric, or inferior mesenteric ganglia). This neuron provides a pathway for gut-to-brain communication via sympathetic prevertebral ganglia. In humans, 89% are immunopositive for choline acetyltransferase (ChAT); CART (cocaine- and amphetamine-regulated transcript) is NOT a human marker (0% CART+) but is present in rodent viscerofugal neurons.

  • viscerofugal neuron (PMID:38292899)
  • VFN (PMID:38292899)
  • cholinergic viscerofugal neuron (PMID:38292899)

Term 5: Ascending interneuron of myenteric plexus

Preferred Label: ascending interneuron of myenteric plexus

Definition: An interneuron of the myenteric plexus whose axon projects orally (in the ascending direction) along the gut axis. This neuron is immunopositive for choline acetyltransferase (ChAT) and enkephalin (ENK), and forms the excitatory limb of ascending reflex pathways that coordinate peristalsis.

@copilot please make this term CL_9900001 subclass of enteric neuron

…ea83 review

CL_9900001 (Dogiel type II neuron) was only a subclass of CL_0000540
(neuron); adding CL_0007011 (enteric neuron) as an additional parent
per reviewer request.

Good for now. Let's aim for a second round with more refs and slightly broadened terms.
