[Expression of transient receptor potential lvanilloidreceptor 4 protein in autoimmune bullous skin disorders].

Objevtive: To investigate the expression of transient receptor potential lvanilloidreceptor 4 (TRPV4) protein in pemphigus vulgaris (PV), bullous pemphigoid (BP), dermatitis herpetiformis (DH), and epidermolysis bullosa acquisita (EBA), and explore the role of TRPV4 in the pathogenesis of these diseases.

Methods: TRPV4 protein in normal skin tissues and lesions of PV, BP, DH, and EBA were detected with immunohistochemistry.

Results: The positivity rate of TRPV4 protein expression was 61.
