“…The main objective of cytotoxic drugs developed in the 20 th century, such as methotrexate, was to reduce keratinocyte proliferation. Immunological studies on psoriatic patients identified changes in humoral immune reactions as part of the overall problem but not the cause (Aswaq et al, 1960;Harber et al, 1962). Efficacy of the cytotoxic drugs in the late 1960s paved the road for ideas about the role of the immune system in psoriasis (Harris, 1971;Landau et al, 1965).…”
