Hello Dr. Rassman,
How about the aid of a phosphorylase kinase inhibitor for the treatment of psoriasis? Could this work? A friend of mine, Dr. Madalene Heng has conducted significant research in this area. (http://psoriainfo.org/)
I do not know much about phosphorylase kinase inhibitors for the treatment of Psoriasis other than what I have read about it at both the site you recommended and at PubMed.gov
As a psoriasis victim myself, I might look into it further.
