ABSTRACT
Objective To construct a recombinant adenovirus vector expressing mouse SPINK5 gene,and observe its curative effect on the skin lesions in atopic dermatitis mice model. Methods By recombining DNA technology,the sequence of mouse SPINK5 gene was cloned into adeno?virus shuttle plasmid. Then it was transformed into HEK 293 cells with the adenoviral backbone plasmid to obtain the recombinant adenovirus. A mouse model of atopic dermatitis was established by system and local sensitization of Balb/c mice with ovalbumin . The effect of recombinant adeno?virus on the lesions of atopic dermatitis mice model was observed. Results The SPINK5 over?expressing adenovirus vector and atopic dermatitis mice model were successfully constructed. After 2 weeks of adenovirus?mediated SPINK5 gene intracutaneous injection,the redness and edema of lesions of AD model mice were obvious relieved. The pathological detection indicated that epidermal thickness and prickle cell layer ,inflammatory cell infiltration significant decreased accompanied with the model blank control. Conclusion The adenovirus?mediated SPINK5 gene had signifi?cant therapeutic effect to the atopic dermatitis mice model ,which provided a laboratory basis of application of SPINK5 gene product to therapy atopic dermatitis.
