Psoriasis is a chronic inflammatory disease which infiltrated a large number of neutrophils among skin lesions. Here, we investigated the contribution of tyrosine phosphatase SHP2 in neutrophils, as well as its pathogenesis in psoriasis. We combined single-cell RNA sequencing with experimental verification to declare that SHP2 in neutrophils could promote the NETs formation through the ERK5 pathway, and resulted in the infiltration of inflammatory immune cells, which leads to psoriasis. Our study provides evidence for the role of SHP2 in NETosis in the progression of psoriasis, and SHP2 may be a potential therapeutic target for the treatment of psoriasis.
