For the main label, I think we should go with the most commonly used name. For example, when I Google "Purkinje cell" (with the quotes) I get 955'000 results, but "Purkinje neuron" gives only 75'500 results. Of course we can and should put the synonyms in as well.
Thanks, @MaaikevS for the very nice groundwork ☺️ This makes it a lot easier to discuss this topic.

Thanks for your insights here. I agree. Some of the cell types listed here basically don't exist as "neuron", e.g. "granule cell" and of course @apdavison example.
We should however prefer "neuron" over "cell" whenever there is no clear tendency (but a neuron is meant). So, @MaaikevS, all "XX-expressing cell" should be changed to "XX-expressing neuron". It will also make it more explicit and detailed, since I'm pretty sure that all our use cases mean exactly that and not other non-neuronal cells expressing a certain protein.
@lzehl commented in the PR openMetadataInitiative/openMINDS_controlledTerms#150 that she would like to avoid semantic combinations of brain regions and cell types (e.g. cortical neuron). But I would disagree. We do not have an unambiguous way of stating the combination of brain region + (generic) cell type and the location of the cell in the brain has an impact on the e.g. the cell's function and morphology. Even for cell types that only exist in a single brain region, it might be nice to add the brain region because not everybody just has this intrinsic knowledge about every cell type - myself included. Adding cell type instances is actually challenging for me in relation to that. The time that I had to spent to figure out whether or not a specific cell type only exists in one place or not, is pretty absurd... Also not entirely irrelevant: This is also how they are registered in InterLex. The generic types basically don't exist there (e.g. granule cell again: https://neuinfo.org/interlex/search?q=granule+cell). It still makes sense for us to add the generic types, but I would not remove the combinations.
I merged the requested cell types from PR openMetadataInitiative/openMINDS_controlledTerms#150 into the list below. I reorganized them to have similar ones closer to each other and added my suggested changes (and synonyms).

General preferences in this proposal:
cell == neuron: "neuron" preferred over "cell" if both are used equally
cell == neuron: "cell" preferred if this is more often used than "neuron"
cell != neuron: obviously "cell"
brain regions: e.g. cerebellar/cortical/striatal preferred over cerebellum/neocortex/(neo)striatum
brain regions: preferably included, but generic ones may exist too
XX - expressing cells: protein preferably same name as used for the corresponding molecular entity (e.g. D1 receptor)
XX - expressing cells: written as "XX expressing neuron" (no "-" between protein and expressing)
@UlrikeS91 I worry about the combination of terms (cell type + brain region) because it infers that there is something very special about this neuron type compared to the same neuron type in other regions which is not always the case (even if they are used as terms in the community). And we don't have the knowledge to research if the combination is valid and deserves its own term or not. Even if we say we don't care, where do you stop combining? For me this is a bottomless pit which we should solve in a better way.
In my opinion: If we need non-ambiguous combinations of brain regions and cell types we should create a small schema that allows for this (UBERON parcellation + cell type). Although as study target combination (on a protocol execution) this should actually be non-ambiguous already.
Nonetheless we can later come back to the issue and now do not touch this topic. If we discuss this further we anyway should meet with experts in the field to get a better insight.
I agree with Lyuba's observation that brain region + cell type give the impression that the cell type is different, which may not always be the case. In some cases the cell type only/predominantly exists in a particular brain region, so in those cases one could argue that it is fine to use the combination. Nevertheless, it might be a good idea to put the cell types that fall into that category ("with anatomical region" on hold until we can consult some experts.
I would propose to proceed with the other changes though.
I would be happy to start working on this so that we can also continue with the clean up of the term suggestion. @UlrikeS91 @lzehl Would this work for you too?
I see your points and generally agree. I also like the suggestion to add a small schema to state such relations more clearly. I don't have any experience as to whether or not this would be problematic on the protocolExecution schema at the moment, but I suspect that some could in fact turn out to be ambiguous. But as long as we haven't experienced any issue, it should be fine to remove the brain regions from the cell types.
Either way, I support @MaaikevS suggestion to proceed with some parts of the clean up already. If @lzehl is fine with my proposed naming convention (excluding the brain region stuff), then we could already implement those changes. More importantly, also add new cell types without introducing more chaos. @MaaikevS already suggested new cell types and more may come, so we cannot avoid adding new instances until we have reached a complete conclusion.
@UlrikeS91 and @MaaikevS the suggested naming convention (excluding the brain region combination) seemed fine to me. @MaaikevS I agree with your approach.
@lzehl @UlrikeS91 I made the changes as suggested. Once these changes are approved, I will clean up the term suggestions
open TODOs are commented in: https://github.com/HumanBrainProject/openMINDS_controlledTerms/issues/257
@lzehl @UlrikeS91 We briefly talked about the naming convention of cell types offline. The thought was that we should use "neuron" if it can only be a neuron, otherwise "cell". It looks like there were some inconsistencies introduced in the past. Would this be something to clean up now (before adding more)?
This is the list we have at the moment:
astrocyte basket cell cerebellar interneuron cerebellum basket cell cerebellum Golgi cell cerebellum granule cell cerebellum stellate neuron cholecystokinin expressing cell cholinergic interneuron cholinergic neuron cortical basket cell cortical interneuron D1 receptor expressing cell dopaminergic neuron fast spiking interneuron glial cell granule cell hippocampus CA1 pyramidal neuron interneuron macroglial cell microglial cell motor neuron neocortex layer 2/3 pyramidal neuron neocortex layer 5 tufted pyramidal neuron neostriatum cholinergic interneuron neostriatum direct pathway spiny neuron neostriatum indirect pathway spiny neuron neuron parvalbumin expressing cell Purkinje cell pyramidal cell sensory neuron somatostatin expressing cell spinal interneuron spiny neuron stellate neuron striatal interneuron striatum medium spiny neuron vascular endothelial cell vascular smooth muscle cell vasoactive-intestinal peptide expressing cell
I would say, the following ones are the most relevant. If you want to keep it the way it is, then I feel that any new cell types should also have the name "cell" instead of "neuron":
cholecystokinin expressing cell D1 receptor expressing cell parvalbumin expressing cell somatostatin expressing cell vasoactive-intestinal peptide expressing cell
