In addition, miR-155 has been identified as a potential therapeutic target for psoriasis [94]; indeed, it is markedly increased in lesional skin and PBMCs of psoriasis patients and plays several crucial roles in keratinocyte proliferation and apoptosis inhibition—through the phosphatase and tension homolog deleted on chromosome 10 (PTEN) signaling pathway—as well as in inflammatory pathways [94,95,96]. The gene discussed is PTEN; the disease is psoriasis.
