conceal rules

I added a couple of personal conceal rules to my vim config files (such as 'syn match texMathSymbol '\\ell\>' contained conceal cchar=ℓ'). 

But I struggled with a few.  Can anybody help with these?

I would like to replace '\{' by '{' and '\}' by '}'. Also '\item' by '•'. Finally I would like to replace '\,' and '\;' and '&' by ' ', i.e. an empty space (works fine with \quad and \qquad).

Cheers
