Psoriasis is a common chronic inflammatory disease of the skin. Its pathogenesis has not been completely elucidated. Phosphoinositide-3 kinase/protein kinase-B/mammalian target of rapamycin (PI3K/Akt/mTOR) pathway has been identified as a key signaling pathway for important cellular functions. The data collected in this review suggest that overexpression of the PI3K/Akt/mTOR pathway may play an important role in the pathogenesis of psoriasis by mediating the immune-pathogenesis, the epidermal hyperplasia or/and the angiogenesis in the disease. Advances in understanding the pathogenesis of psoriasis has provided new insight into potential therapeutic targets, including the development of biological therapies, resulting in remarkable clinical responses in patients with severe psoriasis. More recently, small molecule oral preparations targeting intracellular signaling that may prove effective have been developed. Data suggest that PI3K/Akt/mTOR pathway may be a potential target for treatment of psoriasis.
