Grep, Italicise words between curly brackets and remove the curly brackets

New to GREP but I'm fairly sure it's the solution to my needs. I know this is an old thread, but I'm hoping someone will see it and can help with a similar issue and possibly share what the code would look like and how best to use it.

In my case, the text is one or more words in between braces. I need the words in between italicized and the braces removed.

Example: {Miracle on 34th Street} should change to Miracle on 34th Street

Any help would be so much appreciated! Thank you in advance.
