Abstract:
Objective To study the role of calcitonin-gene-related peptide (CGRP) and substance P (SP) in the pathogenesis of prurigo nodularis. Methods SABC immunohistochemical technique was used to examine the expression of CGRP and SP in lesional skin and uninvolved skin of 30 cases of prurigo nodularis and in skin of 15 normal controls. Results The strong expression of CGRP and SP was observed in the whole epidermis of lesional skin in 30 cases, with the expression surrounding cell membranes. The weak expression of CGRP and SP was observed in nonlesional and normal epidermis. CGRP and SP expression levels had significant differences in the lesional skin and in normal and uninvolved skin (P
