You have seen the commercials for it -
Enbrel .
Drugs.com - Enbrel info.
Many of the NIH studies are showing that further study is needed, however it does look positive, with perispinous injections of etanercept; and I found one
reference to the addition of minocycline with the etanercept.
And I did find
this maybe referencing the S-100b protein and etanercept.
