[Typo/Bug] Equivalence axiom of 'Schwann cell' too broad

[ghost]

CL term CL:0002573 'Schwann cell'

Description of typo, bug or error Whilst reviewing a PR, it was realised that the current equivalence axiom for 'Schwann cell' would incorrectly classify some glial cells as Schwann cells.

CURRENT EQUIVALENCE AXIOM:

'glial cell' and ('part of' some 'peripheral nervous system')

This causes an 'enteroglial cell' to be inferred as a 'Schwann cell', which seems to be inaccurate.

See also https://doi.org/10.1002/9781118402061.ch8: There are four major types of glia in the PNS. They are myelinating and non-myelinating Schwann cells, satellite glial cells (SGCs), enteric glial cells (EGCs), and olfactory ensheathing cells (OECs).

Based on the above, not all glial cells of the PNS are 'Schwann cells'.

PROPOSED FIX:

• Remove current equivalence axiom
• add subclass axioms:
  • 'glial cell'
  • 'part of' some 'peripheral nervous system'
• Fix grammar in text definition
