"Getting cancer drugs into the brain," an article by Eric Bender, is part of the Nature Outlook publication Brain Cancer published this week. This is a well written article that covers many of the different strategies currently being developed/tested for getting therapeutics across the BBB. Note: "This Nature Outlook is editorially independent. It is produced with third party financial support." Thanks to digitel over on Stockhouse for first posting on this article.
