PN could be primary or secondary. The exact immune pathogenesis of PN is not yet clear, and multiple pathways are proposed with the JAK\u2010STAT pathway rarely being investigated.<\/jats:p><\/jats:sec><jats:sec><jats:title>Aims<\/jats:title><jats:p>In this study, our aim was to assess the role of Th cells in PN by comparing the expression of STAT 1, 3, and 6 in involved and normal skin of primary prurigo nodularis.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A total of 49 clinico\u2010histopathologically proven cases of primary prurigo nodularis were included. Two skin biopsies for each patient from lesional and non\u2010lesional skin were stained with STAT 1, 3, and 6, and the nuclear staining pattern in the epidermis was graded as strong, moderate, weak, or none.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Statistically significant expression of STAT 3 and STAT 6 staining was seen in the epidermis of the lesional skin as

signifies that the keratinocytes play an important role in PN and suggest that Th2, Th17, and Th22 cytokines mediate the tissue response in
