Cytokinetics and chemotherapy of psoriasis.
The successful treatment of psoriasis with folic acid antagonists during the past 25 years has led to extensive research in the areas of cytokinetics and chemotherapy. In this paper we shall review selected aspects of these topics relevant to the treatment of psoriasis. The effectiveness of methotrexate treatment of psoriasis can be related to both the hyperproliferative cytokinetics of psoriasis and an increased biochemical sensitivity of psoriatic epidermal cells to this drug. Future research goals in chemotherapy of psoriasis include (a) optimizing drug schedules for available drugs; (b) identifying other susceptible biochemical points of selective drug attack; (c) identifying secondary advantages in order to facilitate selective drug action in psoriasis, such as ultraviolet light therapy in combination with a systemic drug; and (d) developing topically effective chemotherapeutic agents. Approaches to research on topical therapy are reviewed with specific reference to animal testing models for psoriasis and percutaneous penetration of topically applied agents.
