Summary

Transcriptomics is the study of how RNA is expressed under specific conditions. Transcriptomic analyses of lesional skin biopsies can be a useful way to track how a patient responds to a drug and separate out drug responders from non-responders. However, biopsies are painful, carry risk of bleeding infections and scarring. A non-invasive approach, such as tape-harvesting, to obtain transcriptomic data from psoriatic skin would increase our capabilities to monitor patients on treatment and potentially help us predict if the drug will be effective sooner. However, it is not known how well tape-harvesting can capture transcriptomic changes that are occurring in psoriatic skin. The purpose of this study is to address how well tape-harvesting captures the transcriptomic changes that are occurring in psoriatic skin.

Conditions

Interventions

PROCEDURE

Skin Tape Stripping

For psoriasis group, tape-stripping will be done in both involved and uninvolved skin. The tape-stripping will be performed within 2.5 cm of the first punch biopsy. For healthy control group, tape-stripping will be performed on normal skin, within 2.5. cm of the first punch biopsy.

PROCEDURE

Punch Biopsy

For psoriasis group, one punch biopsy will be taken from each of the following areas: involved skin, tape-stripped involved skin, uninvolved skin, and tape-stripped uninvolved skin. For healthy control group, one punch biopsy will be taken from each of the following areas: normal skin and tape-stripped normal skin (within 2.5 cm of the first punch biopsy).
