Mrs Cortez, our neighbour, is from Mexico.
The term for \\\'our neighbour\\\' is an appositive, and it gives us further information to identify whom the speaker is referring to.
However, Mrs Cortex would have been sufficient, so \\\'our neighbour\\\' is additional, but not essential information that is interjected, and separated off with commas.
Note, that if the sentence was:
Our neighbour Mrs Cortez is from Mexico.
that no comma is used, because \\\'our neighbour\\\' does not clearly identify who this person from Mexico is. We need the whole \\\'Our neighbour Mrs Cortez\\\' before we are sure, and so no comma is used.
One final thing: when an abbreviation is made from the first AND last letters, no full stop is used, hence:
Mrs Cortez
