chemoreceptor cell: "A cell specialized to detect chemical substances and relay that information centrally in the nervous system." Equivalent to: neuron and capable of some detection of chemical stimulus involved in sensory perception
Is there evidence that lung neuroendocrine cells relay chemosensory info to the nervous system / function in sensory perception? If not, the classification is not correct.
chemosensory is also very general. Better to record something more specific about function
I suggest
subClassof: detection of hypoxia (http://purl.obolibrary.org/obo/GO_0070483)

Thanks for the review. PMID:33355253 provides evidence to align with the text definition of 'chemoreceptor cell':
The same reference states: "[pulmonary neuroendocrine cells] can detect hypoxic conditions through chemoreception".
CL also (possibly controversially) defines neuroendocrine cells as neurons, so that is aligned with the logical definition of 'chemoreceptor cell'.
Thank you for the GO term suggestion.
ACTIONS:
[x] Add SubClass of 'capable of' some 'detection of hypoxia'
@dosumis, if you still have reservations of keeping SubClass Of 'chemoreceptor cell' after the justification above, kindly advise.
The text def should include information about the interaction of these cells with sensory (and other) nerve terminals and should be explicit about their sensory role.
(Notes - more minor issues:
• This is a good example of why standard citation practice in defs is a good thing - it would point me and anyone else directly to the relevant paper supporting specific assertions,. Will get more important if the number of refs increases.)
Could also add:
subClassOf: has_part some 'dense core granule' http://purl.obolibrary.org/obo/GO_0031045
The text def should include information about the interaction of these cells with sensory (and other) nerve terminals and should be explicit about their sensory role.
What is your proposed revision to make this a necessary and sufficient text definition?

This point was discussed multiple times already in CL/EBI meetings and voted against. Currently CL text definitions are not intended to be discursive descriptions and should therefore not require a high number of cross-references. Feel free to add to a future CL meeting agenda for further discussion.
ACTION:
remove SubClass Of 'chemoreceptor cell'
I agree with @bvarner-ebi to maintain SubclassOf 'chemoreceptor cell', or at least add'part of' some 'sensory system'
(see https://doi.org/10.7554/eLife.78216).
I am now convinced that there is enough evidence to assert the sensory role
What is your proposed revision to make this a necessary and sufficient text definition?
My point is that a sensory role should be clear to anyone reading the text def. It is currently not 'detecting enrvironmental stimuli != role in sensory perception. Mentioning connection to afferent and efferent nerve fibers makes potential sensory and effector (neuroendocrine) roles much clearer. How about:
"A neuroendocrine cell that is part of respiratory epithelium of the lung and is involved in the sensory detection of environmental stimuli, including hypoxic conditions.. Ultrastructurally, this cell type is characterized by the presence of cytoplasmic dense core secretory granules. Lung neuroendocrine cells are associated with both afferent and efferent nerve terminals. They appear as solitary cells or as clustered masses, localized at airway bifurcation sites, called neuroepithelial bodies that can release serotonin in response to hypoxia. The lung neuroendocrine cell type is also reported to have stem cell properties."
I'm also not keen on the last sentence. We should avoid terms like 'reported' in defs and 'stem cell properties' is vague. If the evidence is strong enough we should have a clear assertion of properties, e.g. stating that these cells are capable of acting as stem cells or giving rise to stem cells. Otherwise, this is better relegated to a comment.

Agreed on last sentence. Will change to: "Lung neuroendocrine cells also function as reserve stem cells that repair the surrounding epithelium after injury." doi:10.7554/eLife.78216
"Lung neuroendocrine cells are associated with both afferent and efferent nerve terminals."
If you would like this sentence added, please provide a reference that asserts this for both solitary cells as well as those in the neuroepithelial bodies. In my review, I've only read about the efferent connections in the neuroepithelial bodies.

Can you give an example in animals where detecting an environmental stimulus does not involve sensory perception?
Thank you for the feedback, @dosumis. Hopefully the revised text definition reflects your suggestions.
Inspired by #2081.
After reviewing the Cell Guide "Experimental Description" for 'lung neuroendocrine cell' and finding cross-references to validate aspects of the description, the following edits are proposed:
CL:1000223 ‘lung neuroendocrine cell’
[x] add text definition: "A neuroendocrine cell that is part of respiratory epithelium of the lung and is involved in the sensory detection of environmental stimuli, including hypoxia, nicotine and air pressure. Ultrastructurally, this cell type is characterized by the presence of cytoplasmic dense core granules, which are considered the storage sites of amine and peptide hormones. Lung neuroendocrine cells are innervated and appear as solitary cells or as clustered masses, localized at airway bifurcation sites, called neuroepithelial bodies that can release serotonin in response to hypoxia and interact with sensory nerve terminals. Lung neuroendocrine cells also function as reserve stem cells that repair the surrounding epithelium after injury." PMID:33355253 doi:10.3109/01902148209069653 doi:10.7554/eLife.78216
[x] add SubClass of axioms:
'chemoreceptor cell'
‘capable of’ some ‘serotonin secretion’
'capable of' some 'detection of hypoxia'
'has part' some 'dense core granule'
[x] add synonyms:
"pulmonary neuroendocrine cell", exact, PMID:33355253
"PNEC", related, abbreviation, PMID:33355253
UBERON:0010002 'pulmonary neuroendocrine body' (Uberon ticket: https://github.com/obophenotype/uberon/issues/3035)
