Summary

This study aims to elucidate the role of Chemokine and chemokine receptor in the pathogenesis of Psoriasis by using human psoriasis skin xenograft SCID mouse model. The hypothesis is that chemokine and chemokine receptor play important roles in psoriasis and establishment of human skin xenograft mouse model provide excellent platform to test the hypothesis.

PROCEDURE

Shave Biopsy of Psoriasis Lesion

The investigator will take about 0.5x0.5 inch square section of skin from the psoriasis lesion. To numb the skin, the subject will receive a small injection of 0.5% lidocaine HCl 5mg/mL with 1:200,000 mcg/mL epinephrine solution as per standard shave biopsy protocol. The shaving instrument has a blade that will shave off a superficial piece of skin that is less than \<3mm in thickness. After 14 days, the subject will return to make sure that the skin biopsy site has healed properly. The piece of skin that is removed will be grafted onto the back of an immunocompromised SCID mouse. An approved IACUC protocol covering this procedure will be in place prior to engraftment.
