Effect of substance P and epidermal growth factor receptor on the pathogenesis of early psoriasis / 西安交通大学学报(医学版)

ABSTRACT

Objective To explore the pathogenesis of substance P (SP) and epidermal growth factor receptor (EGFR) in early psoriasis vulgaris. Methods SP and EGFR were detected in normal skin tissues and psoriatic lesions by radioimmunoassay. Results Expression of SP was significantly enhanced in active and stable psoriasis than in recovery lesions and normal ones (P 0.05). Conclusion SP and EGFR may work together to play a key role in the early pathogenesis of psoriasis.
