    Autophagy is an important biological process, which involves intracellular quality control, metabolism and cell survival , enabling cells to recover cytoplasmic material under stress conditions


    Quality control of the cell metabolism and cell survival development, innate immunity, antigen presentation and lymphocyte antigen receptor signal transmission


    AD and psoriasis biopsies and KCs TNF treated with long-term showed P accumulated 62 / SQSTM1, it is usually degraded autophagic process, indicating that despite the increased formation of autophagic body, but the waste is processed by the Hinder


    Decreased expression of cathepsin D and L may be the cause of psoriatic hypokeratosis.


    Autophagy in immunization another prominent feature is the inhibition of the synthesis of proinflammatory cytokines, including IL-1 in the synthesis of type I interferon


    Other functions mediated by autophagy may not be conducive to the treatment of skin-related autoimmune diseases


    KCs hyperplasia is another feature of psoriasis TCR stimulation increases autophagy, and the lack of regulatory factor substantially autophagy mouse thymocytes and the CD .
